Detailed Description
Frontend action adaptor that merges ASTs together.
This action takes an existing AST file and "merges" it into the AST context, producing a merged context. This action is an action adaptor, which forwards most of its calls to another action that will consume the merged context.

BeginSourceFileAction - Callback at the start of processing a single input.
- Returns:
- True on success; on failure
- See also:
- ExecutionAction() and EndSourceFileAction() will not be called.

CreateASTConsumer - Create the AST consumer object for this action, if supported.
This routine is called as part of
- See also:
- BeginSourceAction(), which will fail if the AST consumer cannot be created. This will not be called if the action has indicated that it only uses the preprocessor.
- Parameters:
-
CI - The current compiler instance, provided as a convenience,
- See also:
- getCompilerInstance().
- Parameters:
-
InFile - The current input file, provided as a convenience,
- See also:
- getCurrentFile().
- Returns:
- The new AST consumer, or 0 on failure.

| void ASTMergeAction::EndSourceFileAction | ( | ) | [protected, virtual] |
EndSourceFileAction - Callback at the end of processing a single input; this is guaranteed to only be called following a successful call to BeginSourceFileAction (and BeginSourceFile).

| void ASTMergeAction::ExecuteAction | ( | ) | [protected, virtual] |
ExecuteAction - Callback to run the program action, using the initialized compiler instance.
This routine is guaranteed to only be called between

- EndSourceFileAction().
