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.

See also
LexerInputState

Reimplemented from InputBuffer.
