Constructor & Destructor Documentation

PxDefaultFileInputData::PxDefaultFileInputData ( const char *  name  ) 

virtual PxDefaultFileInputData::~PxDefaultFileInputData (  )  [virtual]


Member Function Documentation

virtual PxU32 PxDefaultFileInputData::getLength (  )  const [virtual]

return the length of the input data

Returns:
size in bytes of the input data

Implements PxInputData.

bool PxDefaultFileInputData::isValid (  )  const

virtual PxU32 PxDefaultFileInputData::read ( void *  dest,
PxU32  count 
) [virtual]

read from the stream. The number of bytes read may be less than the number requested.

Parameters:
[in] dest the destination address to which the data will be read
[in] count the number of bytes requested
Returns:
the number of bytes read from the stream.

Implements PxInputStream.

virtual void PxDefaultFileInputData::seek ( PxU32  offset  )  [virtual]

seek to the given offset from the start of the data.

Parameters:
[in] offset the offset to seek to. If greater than the length of the data, this call is equivalent to seek(length);

Implements PxInputData.

virtual PxU32 PxDefaultFileInputData::tell (  )  const [virtual]

return the current offset from the start of the data

Returns:
the offset to seek to.

Implements PxInputData.
