Detailed Description

Simple data item provider implementation that handles the support for provider plugins (which may contain dataCapabilities() and dataItem() functions).

Ideally the provider plugins should directly provide implementation of QgsDataItemProvider, for the time being this is a wrapper for the legacy interface.

Note: not available in Python bindings

Member Function Documentation

int QgsDataItemProviderFromPlugin::capabilities ( )

inlineoverridevirtual

Returns combination of flags from QgsDataProvider::DataCapabilities.

Implements QgsDataItemProvider.

Definition at line 57 of file qgsdataitemproviderregistry.cpp.

QgsDataItem* QgsDataItemProviderFromPlugin::createDataItem	(	const QString &	path,
		QgsDataItem *	parentItem
	)

inlineoverridevirtual

Create a new instance of QgsDataItem (or null) for given path and parent item.

Caller takes responsibility of deleting created items.

Implements QgsDataItemProvider.

Definition at line 59 of file qgsdataitemproviderregistry.cpp.

bool QgsDataItemProviderFromPlugin::handlesDirectoryPath ( const QString & path )

inlineoverridevirtual

Returns true if the provider will handle the directory at the specified path.

If the provider indicates that it will handle the directory, the default creation and population of directory items for the path will be avoided and it is left to the provider to correctly populate relevant entries for the path.

The default implementation returns false for all paths.
