Constructor & Destructor Documentation

preprocessor::preprocessor

(

preprocessor_streambuf &

t

)

[protected]

Sets up a new preprocessor for stream buffer t.

Saves the current preprocessing context of target_. It will be automatically restored on destruction.

Definition at line 363 of file preprocessor.cpp.

References preprocessor_streambuf::current_, preprocessor_streambuf::depth_, and target_.

preprocessor::~preprocessor

(

)

[virtual]

Restores the old preprocessing context of target_.

Appends location and domain directives to the buffer, so that the parser notices these changes.

Member Function Documentation

virtual bool preprocessor::get_chunk

(

)

[pure virtual]

Preprocesses and sends some text to the target_ buffer.

Returns:

false when the input has no data left.

Implemented in preprocessor_file, and preprocessor_data.
