Resolver

The object that handles DNS resolution. Use gio.resolver.Resolver.getDefault to get the default resolver.

gio.resolver.Resolver provides cancellable synchronous and asynchronous DNS resolution, for hostnames (gio.resolver.Resolver.lookupByAddress, gio.resolver.Resolver.lookupByName and their async variants) and SRV (service) records (gio.resolver.Resolver.lookupService).

gio.network_address.NetworkAddress and gio.network_service.NetworkService provide wrappers around gio.resolver.Resolver functionality that also implement gio.socket_connectable.SocketConnectable, making it easy to connect to a remote host/service.

The default resolver (see gio.resolver.Resolver.getDefault) has a timeout of 30s set on it since GLib 2.78. Earlier versions of GLib did not support resolver timeouts.

This is an abstract type; subclasses of it implement different resolvers for different platforms and situations.

Functions

connectReload ulong connectReload(T callback, Flag!"After" after): Connect to Reload signal.
getTimeout uint getTimeout(): Get the timeout applied to all resolver lookups. See #GResolver:timeout.
lookupByAddress string lookupByAddress(gio.inet_address.InetAddress address, gio.cancellable.Cancellable cancellable): Synchronously reverse-resolves address to determine its associated hostname.
lookupByAddressAsync void lookupByAddressAsync(gio.inet_address.InetAddress address, gio.cancellable.Cancellable cancellable, gio.types.AsyncReadyCallback callback): Begins asynchronously reverse-resolving address to determine its associated hostname, and eventually calls callback, which must call gio.resolver.Resolver.lookupByAddressFinish to get the final result.
lookupByAddressFinish string lookupByAddressFinish(gio.async_result.AsyncResult result): Retrieves the result of a previous call to gio.resolver.Resolver.lookupByAddressAsync.
lookupByName gio.inet_address.InetAddress[] lookupByName(string hostname, gio.cancellable.Cancellable cancellable): Synchronously resolves hostname to determine its associated IP address(es). hostname may be an ASCII-only or UTF-8 hostname, or the textual form of an IP address (in which case this just becomes a wrapper around gio.inet_address.InetAddress.newFromString).
lookupByNameAsync void lookupByNameAsync(string hostname, gio.cancellable.Cancellable cancellable, gio.types.AsyncReadyCallback callback): Begins asynchronously resolving hostname to determine its associated IP address(es), and eventually calls callback, which must call gio.resolver.Resolver.lookupByNameFinish to get the result. See gio.resolver.Resolver.lookupByName for more details.
lookupByNameFinish gio.inet_address.InetAddress[] lookupByNameFinish(gio.async_result.AsyncResult result): Retrieves the result of a call to gio.resolver.Resolver.lookupByNameAsync.
lookupByNameWithFlags gio.inet_address.InetAddress[] lookupByNameWithFlags(string hostname, gio.types.ResolverNameLookupFlags flags, gio.cancellable.Cancellable cancellable): This differs from gio.resolver.Resolver.lookupByName in that you can modify the lookup behavior with flags. For example this can be used to limit results with gio.types.ResolverNameLookupFlags.Ipv4Only.
lookupByNameWithFlagsAsync void lookupByNameWithFlagsAsync(string hostname, gio.types.ResolverNameLookupFlags flags, gio.cancellable.Cancellable cancellable, gio.types.AsyncReadyCallback callback): Begins asynchronously resolving hostname to determine its associated IP address(es), and eventually calls callback, which must call gio.resolver.Resolver.lookupByNameWithFlagsFinish to get the result. See gio.resolver.Resolver.lookupByName for more details.
lookupByNameWithFlagsFinish gio.inet_address.InetAddress[] lookupByNameWithFlagsFinish(gio.async_result.AsyncResult result): Retrieves the result of a call to gio.resolver.Resolver.lookupByNameWithFlagsAsync.
lookupRecords glib.variant.VariantG[] lookupRecords(string rrname, gio.types.ResolverRecordType recordType, gio.cancellable.Cancellable cancellable): Synchronously performs a DNS record lookup for the given rrname and returns a list of records as #GVariant tuples. See #GResolverRecordType for information on what the records contain for each record_type.
lookupRecordsAsync void lookupRecordsAsync(string rrname, gio.types.ResolverRecordType recordType, gio.cancellable.Cancellable cancellable, gio.types.AsyncReadyCallback callback): Begins asynchronously performing a DNS lookup for the given rrname, and eventually calls callback, which must call gio.resolver.Resolver.lookupRecordsFinish to get the final result. See gio.resolver.Resolver.lookupRecords for more details.
lookupRecordsFinish glib.variant.VariantG[] lookupRecordsFinish(gio.async_result.AsyncResult result): Retrieves the result of a previous call to gio.resolver.Resolver.lookupRecordsAsync. Returns a non-empty list of records as #GVariant tuples. See #GResolverRecordType for information on what the records contain.
lookupService gio.srv_target.SrvTarget[] lookupService(string service, string protocol, string domain, gio.cancellable.Cancellable cancellable): Synchronously performs a DNS SRV lookup for the given service and protocol in the given domain and returns an array of #GSrvTarget. domain may be an ASCII-only or UTF-8 hostname. Note also that the service and protocol arguments do not include the leading underscore that appears in the actual DNS entry.
lookupServiceAsync void lookupServiceAsync(string service, string protocol, string domain, gio.cancellable.Cancellable cancellable, gio.types.AsyncReadyCallback callback): Begins asynchronously performing a DNS SRV lookup for the given service and protocol in the given domain, and eventually calls callback, which must call gio.resolver.Resolver.lookupServiceFinish to get the final result. See gio.resolver.Resolver.lookupService for more details.
lookupServiceFinish gio.srv_target.SrvTarget[] lookupServiceFinish(gio.async_result.AsyncResult result): Retrieves the result of a previous call to gio.resolver.Resolver.lookupServiceAsync.
setDefault void setDefault(): Sets resolver to be the application's default resolver (reffing resolver, and unreffing the previous default resolver, if any). Future calls to gio.resolver.Resolver.getDefault will return this resolver.
setTimeout void setTimeout(uint timeoutMs): Set the timeout applied to all resolver lookups. See #GResolver:timeout.

Static functions

getDefault gio.resolver.Resolver getDefault(): Gets the default #GResolver. You should unref it when you are done with it. #GResolver may use its reference count as a hint about how many threads it should allocate for concurrent DNS resolutions.

From ObjectG

setGObject void setGObject(void* cObj, Flag!"Take" take): Set the GObject of a D ObjectG wrapper.
cPtr void* cPtr(Flag!"Dup" dup): Get a pointer to the underlying C object.
ref_ void* ref_(void* gObj): Calls g_object_ref() on a GObject.
unref unref(void* gObj): Calls g_object_unref() on a GObject.
getType GType getType(): Get the GType of an object.
gType GType gType [@property getter]: GObject GType property.
self ObjectG self(): Convenience method to return this cast to a type. For use in D with statements.
getDObject T getDObject(void* cptr, Flag!"Take" take): Template to get the D object from a C GObject and cast it to the given D object type.
connectSignalClosure ulong connectSignalClosure(string signalDetail, DClosure closure, Flag!"After" after): Connect a D closure to an object signal.
setProperty void setProperty(string propertyName, T val): Template for setting a GObject property.
getProperty T getProperty(string propertyName): Template for getting a GObject property.
compatControl size_t compatControl(size_t what, void* data)
bindProperty gobject.binding.Binding bindProperty(string sourceProperty, gobject.object.ObjectG target, string targetProperty, gobject.types.BindingFlags flags): Creates a binding between source_property on source and target_property on target.
bindPropertyFull gobject.binding.Binding bindPropertyFull(string sourceProperty, gobject.object.ObjectG target, string targetProperty, gobject.types.BindingFlags flags, gobject.closure.Closure transformTo, gobject.closure.Closure transformFrom): Creates a binding between source_property on source and target_property on target, allowing you to set the transformation functions to be used by the binding.
forceFloating void forceFloating(): This function is intended for #GObject implementations to re-enforce a floating[floating-ref] object reference. Doing this is seldom required: all #GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling gobject.object.ObjectG.refSink.
freezeNotify void freezeNotify(): Increases the freeze count on object. If the freeze count is non-zero, the emission of "notify" signals on object is stopped. The signals are queued until the freeze count is decreased to zero. Duplicate notifications are squashed so that at most one #GObject::notify signal is emitted for each property modified while the object is frozen.
getData void* getData(string key): Gets a named field from the objects table of associations (see gobject.object.ObjectG.setData).
getProperty void getProperty(string propertyName, gobject.value.Value value): Gets a property of an object.
getQdata void* getQdata(glib.types.Quark quark): This function gets back user data pointers stored via gobject.object.ObjectG.setQdata.
getv void getv(string[] names, gobject.value.Value[] values): Gets n_properties properties for an object. Obtained properties will be set to values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.
isFloating bool isFloating(): Checks whether object has a floating[floating-ref] reference.
notify void notify(string propertyName): Emits a "notify" signal for the property property_name on object.
notifyByPspec void notifyByPspec(gobject.param_spec.ParamSpec pspec): Emits a "notify" signal for the property specified by pspec on object.
refSink gobject.object.ObjectG refSink(): Increase the reference count of object, and possibly remove the floating[floating-ref] reference, if object has a floating reference.
runDispose void runDispose(): Releases all references to other objects. This can be used to break reference cycles.
setData void setData(string key, void* data): Each object carries around a table of associations from strings to pointers. This function lets you set an association.
setProperty void setProperty(string propertyName, gobject.value.Value value): Sets a property on an object.
stealData void* stealData(string key): Remove a specified datum from the object's data associations, without invoking the association's destroy handler.
stealQdata void* stealQdata(glib.types.Quark quark): This function gets back user data pointers stored via gobject.object.ObjectG.setQdata and removes the data from object without invoking its destroy() function (if any was set). Usually, calling this function is only required to update user data pointers with a destroy notifier, for example:
thawNotify void thawNotify(): Reverts the effect of a previous call to gobject.object.ObjectG.freezeNotify. The freeze count is decreased on object and when it reaches zero, queued "notify" signals are emitted.
watchClosure void watchClosure(gobject.closure.Closure closure): This function essentially limits the life time of the closure to the life time of the object. That is, when the object is finalized, the closure is invalidated by calling gobject.closure.Closure.invalidate on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, gobject.object.ObjectG.ref_ and gobject.object.ObjectG.unref are added as marshal guards to the closure, to ensure that an extra reference count is held on object during invocation of the closure. Usually, this function will be called on closures that use this object as closure data.
connectNotify ulong connectNotify(string detail, T callback, Flag!"After" after): Connect to Notify signal.
