GetContiguousMemoryRange()

template<typename CONTAINER >

virtual ezArrayPtr<const ezUInt8> ezMemoryStreamContainerWrapperStorage< CONTAINER >::GetContiguousMemoryRange ( ezUInt64  uiStartByte ) const

inlineoverridevirtual

Returns a read-only ezArrayPtr that represents a contiguous area in memory which starts at the given first byte.

This piece of memory can be read/copied/modified in one operation (memcpy etc). The next byte after this slice may be located somewhere entirely different in memory. Call GetContiguousMemoryRange() again with the next byte after this range, to get access to the next memory area.

Chunks may differ in size.

Implements ezMemoryStreamStorageInterface.
