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.
