virtual | ~PxInputStream () |
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.

Implemented in PxDefaultFileInputData, and PxDefaultMemoryInputData.

seek to the given offset from the start of the data.
[in] | offset | the offset to seek to. If greater than the length of the data, this call is equivalent to seek(length); |
Implemented in PxDefaultFileInputData, and PxDefaultMemoryInputData.
