Implementations of this service must fulfill the specifications of the DataInputStream service. It must be chained to an XMarkableStream. Therefore, it provides the XMarkableStream interface, and delegates the calls to the chained object.

The written objects are held until this instance is destroyed. The references to the objects are read as four-byte integers. Data format reads:

	short   InfoLength
	long    ObjectReference  // 0 indicates no object
	UTF     ServiceName      // length of 0 indicates this is only a reference
	long    ObjectLength     // 0 if it is a reference or no object, otherwise the len of the object data
	Object  ObjectData       // the data of the object
	...                      // skipping additional data
	
@guarantees
  • -thread safe
  • -allow buffer size is 2 ^ 31 -1
  • -maximum object reference identifier must be the number of objects.
  • -object reference identifier 0 indicates no object
  • -skip addition data
  • -set the stream position behind the object data
