		PxU32	length
	)

Member Function Documentation

getLength()

virtual PxU32 PxDefaultMemoryInputData::getLength ( ) const

virtual

return the length of the input data

Returns

size in bytes of the input data

Implements PxInputData.

read()

virtual PxU32 PxDefaultMemoryInputData::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.

seek()

virtual void PxDefaultMemoryInputData::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.

tell()

virtual PxU32 PxDefaultMemoryInputData::tell ( ) const

virtual

return the current offset from the start of the data

Returns

the offset to seek to.

Implements PxInputData.
