Detailed Description

The byte array wraps a dynamic array of bytes (i.e. char).

It provides convenient methods for loading and unloading data types to and from the byte array. The class acts as an interface definition to raw data (in case the underlying structure of the raw data changes). It's intended use is for socket communications.

By default data using the load/unload methods is appended/removed from the end of the array. Methods are also provided to load/unload from the front of the array. As long as the matching load/unload methods are used, this is transparent to the user.

The internals of ByteArray have been updated to use a dynamically-allocated STL class, for safety and performance reasons. This may limit cross-platform usage of this class (e.g. in the MotoPlus compiler).

THIS CLASS IS NOT THREAD-SAFE

Returns: true on success, false otherwise (max array size exceeded).

Definition at line 67 of file byte_array.cpp.

bool industrial::byte_array::ByteArray::isByteSwapEnabled ( )
