Detailed Description

Base class for preprocessing an input.

Definition at line 196 of file preprocessor.cpp.

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 403 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.

Definition at line 419 of file preprocessor.cpp.

virtual bool preprocessor::get_chunk ( )

pure virtual

Implemented in preprocessor_data, and preprocessor_file.

Referenced by preprocessor_streambuf::underflow().

preprocessor* preprocessor::get_old_preprocessor ( )

inline

Preprocesses and sends some text to the target_ buffer.

Returns

false when the input has no data left.

virtual int preprocessor::is_macro ( )

inlinevirtual

retruns 1 if this parses a macro, -1 if this doesnt parse text (if this is no preprocessor_data). 0 otherwise (this parses a file).

Reimplemented in preprocessor_data.
