Detailed Description

CharInputBuffer.hpp provides an InputBuffer for plain character arrays (buffers).

Constructor & Destructor Documentation

CharInputBuffer()

CharInputBuffer::CharInputBuffer ( unsigned char * buf, size_t size, bool owner = false )

inline

Construct a CharInputBuffer.hpp object with a char* buffer of 'size' if 'owner' is true, then the buffer will be delete[]-ed on destruction.

Note

it is assumed the buffer was allocated with new[]!

~CharInputBuffer()

CharInputBuffer::~CharInputBuffer ( void )

inline

Destructor

Note

If you're using malloced data, then you probably need to change this destructor. Or better use this class as template for your own.

Member Function Documentation

getChar()

virtual int CharInputBuffer::getChar ( void )

inlinevirtual

Override this in subclasses to get the next character

Implements InputBuffer.

reset()

virtual void CharInputBuffer::reset ( void )

inlinevirtual

Reset the CharInputBuffer to initial state Called from LexerInputState::reset.
