◆ clone()

virtual StanzaExtension* clone ( ) const
inlinevirtual

Returns an identical copy of the current StanzaExtension.

Returns
An identical copy of the current StanzaExtension.

Implements StanzaExtension.

Definition at line 120 of file disco.h.

◆ features()

const StringList& features ( ) const
inline

Returns the entity's supported features.

Returns
A list of supported features/namespaces.

Definition at line 80 of file disco.h.

◆ filterString()

const std::string & filterString ( ) const
virtual

Returns an XPath expression that describes a path to child elements of a stanza that an extension handles.

Returns
The extension's filter string.

Implements StanzaExtension.

Definition at line 129 of file disco.cpp.

◆ form()

const DataForm* form ( ) const
inline

Returns an optionally included data form. This is used by e.g. MUC (XEP-0045).

Returns
An optional data form included in the disco::info. May be 0.

Definition at line 99 of file disco.h.

◆ hasFeature()

bool hasFeature ( const std::string &  feature) const

Use this function to check if the entity the Info came from supports agiven feature.

Parameters
featureThe feature to check for.
Returns
True if the entity announces support for the feature, false otherwise.

Definition at line 121 of file disco.cpp.

◆ identities()

const IdentityList& identities ( ) const
inline

Returns the entity's identities.

Returns
A list of pointers to Identity objects.

Definition at line 93 of file disco.h.

◆ newInstance()

virtual StanzaExtension* newInstance ( const Tag tag) const
inlinevirtual

Returns a new Instance of the derived type. Usually, for a derived class FooExtension, the implementation of this function looks like:

StanzaExtension* FooExtension::newInstance( const Tag* tag ) const
{
return new FooExtension( tag );
}
virtual Tag * tag() const
Definition: disco.cpp:135
Returns
The derived extension's new instance.

Implements StanzaExtension.

Definition at line 114 of file disco.h.

◆ node()

const std::string& node ( ) const
inline

Returns the queried node identifier, if any.

Returns
The node identifier. May be empty.

Definition at line 74 of file disco.h.

◆ setForm()

void setForm ( DataForm form)

Adds an optional DataForm, e.g. for XEP-0232. Only one form can be added at this point.

Parameters
formAn optional DataForm to include in the Info reply. The form will be owned by and deleted on destruction of the Info object.
