Member Function Documentation

◆ Clear()

template<typename CONTAINER>

virtual void xiiMemoryStreamContainerWrapperStorage< CONTAINER >::Clear ( )

inlineoverridevirtual

Clears the entire storage. All readers and writers must be reset to start from the beginning again.

Implements xiiMemoryStreamStorageInterface.

◆ Compact()

template<typename CONTAINER>

virtual void xiiMemoryStreamContainerWrapperStorage< CONTAINER >::Compact ( )

inlineoverridevirtual

Deallocates any allocated memory that's not needed to hold the currently stored data.

Implements xiiMemoryStreamStorageInterface.

◆ CopyToStream()

template<typename CONTAINER>

virtual xiiResult xiiMemoryStreamContainerWrapperStorage< CONTAINER >::CopyToStream ( xiiStreamWriter & ref_stream ) const

inlineoverridevirtual

Writes the entire content of the storage to the provided stream.

Implements xiiMemoryStreamStorageInterface.

◆ GetContiguousMemoryRange() [1/2]

template<typename CONTAINER>

virtual xiiArrayPtr< const xiiUInt8 > xiiMemoryStreamContainerWrapperStorage< CONTAINER >::GetContiguousMemoryRange ( xiiUInt64 uiStartByte ) const

inlineoverridevirtual

Returns a read-only xiiArrayPtr 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 xiiMemoryStreamStorageInterface.
