QgsScopedExpressionFunction* GetNamedProjectColor::clone ( ) const

inlineoverridevirtual

Returns a clone of the function.

Implements QgsScopedExpressionFunction.

Definition at line 537 of file qgsexpressioncontext.cpp.

virtual QVariant GetNamedProjectColor::func	(	const QVariantList &	values,
		const QgsExpressionContext *	context,
		QgsExpression *	parent
	)

inlineoverridevirtual

Returns result of evaluating the function.

Parameters

values	list of values passed to the function
context	context expression is being evaluated against
parent	parent expression

Returns: result of function

Note: named funcV2 in Python bindings. Will be renamed to func to replace deprecated method in QGIS 3.0.

Implements QgsScopedExpressionFunction.
