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 ( )

inlinevirtual

Member Function Documentation

virtual PxU32 PxInputData::getLength ( ) const

pure virtual

return the length of the input data

Returns

size in bytes of the input data

Implemented in PxDefaultFileInputData, and PxDefaultMemoryInputData.

virtual void PxInputData::seek ( PxU32  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 PxDefaultFileInputData, and PxDefaultMemoryInputData.

virtual PxU32 PxInputData::tell ( ) const

pure virtual

return the current offset from the start of the data

Returns

the offset to seek to.

Implemented in PxDefaultFileInputData, and PxDefaultMemoryInputData.
