Detailed Description

Abstract base class for actions which can be performed by the frontend.

Member Function Documentation

bool FrontendAction::beginSourceFile	(	CompilerInstance &	ci,
		const FrontendInputFile &	input )

Prepare the action for processing the input file input.

This is run after the options and frontend have been initialized, but prior to executing any per-file processing.

Parameters

ci	- The compiler instance this action is being run from. The action may store and use this object.
input	- The input filename and kind.

virtual bool Fortran::frontend::FrontendAction::beginSourceFileAction ( )

inlineprotectedvirtual

Callback at the start of processing a single input.

Returns: True on success; on failure ExecutionAction() and EndSourceFileAction() will not be called.

void FrontendAction::endSourceFile ( )

Perform any per-file post processing, deallocate per-file objects, and run statistics and output file cleanup code.

virtual void Fortran::frontend::FrontendAction::executeAction ( )

protectedpure virtual

Callback to run the program action, using the initialized compiler instance.

bool FrontendAction::shouldEraseOutputFiles ( )

protectedvirtual

Callback at the end of processing a single input, to determine if the output files should be erased or not.

By default it returns true if a compiler error occurred.
