Detailed Description

Input data class for I/O which provides random read access.

The user needs to supply a PxInputData implementation to a number of methods to allow the SDK to read data.


Constructor & Destructor Documentation

virtual PxInputData::~PxInputData (  )  [inline, virtual]


Member Function Documentation

virtual uint32_t PxInputData::getLength (  )  const [pure virtual]

return the length of the input data

Returns:
size in bytes of the input data

Implemented in PxDefaultMemoryInputData, and PxDefaultFileInputData.

virtual void PxInputData::seek ( uint32_t  offset  )  [pure 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);

Implemented in PxDefaultMemoryInputData, and PxDefaultFileInputData.

virtual uint32_t PxInputData::tell (  )  const [pure virtual]

return the current offset from the start of the data

Returns:
the offset to seek to.

Implemented in PxDefaultMemoryInputData, and PxDefaultFileInputData.
