Detailed Description

CalBufferSource class.

This is an object designed to represent a source of Cal3d data as coming from a memory buffer.


Constructor & Destructor Documentation

CalBufferSource::CalBufferSource ( void *  inputBuffer)

Constructs a buffer source instance from an existing memory buffer.

This function is the only constructor of the buffer source.

Parameters:
inputBufferThe input buffer to read from
CalBufferSource::~CalBufferSource ( ) [virtual]

Destruct the CalBufferSource.

Note that the memory is not deleted here; this should be handled externally.


Member Function Documentation

bool CalBufferSource::ok ( ) const [virtual]

Checks whether the data source is in a good state.

This function checks if the buffer is NULL or not.

Returns:
One of the following values:
  • true if data source is in a good state
  • false if not

Implements CalDataSource.

bool CalBufferSource::readBytes ( void *  pBuffer,
int  length 
) [virtual]

Reads a number of bytes.

This function reads a given number of bytes from this data source.

Parameters:
pBufferA pointer to the buffer where the bytes are stored into.
lengthThe number of bytes that should be read.
Returns:
One of the following values:
  • true if successful
  • false if an error happend

Implements CalDataSource.

bool CalBufferSource::readFloat ( float &  value) [virtual]

Reads a float.

This function reads a float from this data source.

Parameters:
valueA reference to the float into which the data is read.
Returns:
One of the following values:
  • true if successful
  • false if an error happend

Implements CalDataSource.

bool CalBufferSource::readInteger ( int &  value) [virtual]

Reads an integer.

This function reads an integer from this data source.

Parameters:
valueA reference to the integer into which the data is read.
Returns:
One of the following values:
  • true if successful
  • false if an error happend

Implements CalDataSource.

bool CalBufferSource::readString ( std::string &  strValue) [virtual]

Reads a string.

This function reads a string from this data source.

Parameters:
valueA reference to the string into which the data is read.
Returns:
One of the following values:
  • true if successful
  • false if an error happend

Implements CalDataSource.
