Detailed Description

template<class MemoryObject, class MemoryObjectMetaInfo = MetaInfoSizeBase>
class armarx::SharedMemoryConsumer< MemoryObject, MemoryObjectMetaInfo >

The SharedMemoryConsumer opens an existing shared memory segment for reading. It provides synchronized read access to the shared data. The memory content is an array of objects, where the object type is specified as template parameter. The SharedMemoryConsumer needs to be constructed, after a SharedMemoryProvider has been created.
