Member Function Documentation

int QgsExpression::SharedFunctionPtrList::functionIndex ( const QString & name ) const

Returns the index of the function in the list.

Name matching is case-insensitive, and applied against function aliases too.

The returned index applies to this container only, and may differ from indices for other SharedFunctionPtrList instances.

QgsExpression::SharedFunctionPtr QgsExpression::SharedFunctionPtrList::getFunction ( int index ) const

Returns a shared pointer for the function with the specified index.

Definition at line 179 of file qgsexpression.cpp.

void QgsExpression::SharedFunctionPtrList::updateFunctionNameMap ( )

Updates the map of function names to indices.

This should be called ONLY after initially populating a new instance of the list, while only a single reference to the list is held.
