class MigrateAction

Declaration

class MigrateAction : public WrapperFrontendAction { /* full declaration omitted */ };

Description

A frontend action which simply wraps some other runtime-specified frontend action. Deriving from this class allows an action to inject custom logic around some existing action's behavior. It implements every virtual method in the FrontendAction interface by forwarding to the wrapped action.

Methods

¶bool BeginInvocation(clang::CompilerInstance& CI)

Description

Callback before starting processing a single input, giving the opportunity to modify the CompilerInvocation or do some other action before BeginSourceFileAction is called.

Parameters

clang::CompilerInstance& CI

Returns

True on success; on failure BeginSourceFileAction(), ExecuteAction() and EndSourceFileAction() will not be called.
