Direct Known Subclasses:

GroupPointer, SegmentPointer

Deprecated.

public abstract class Pointer
extends Object

A Pointer is a placeholder used in parsing traditionally encoded messages (which do not explicitly identify segment groups). Implementations of Pointer include SegmentPointer, which "points" to a Segment slot. This pointer can exist whether or not the underlying Segment object has been created. There is only one pointer per slot - multiple repetitions are accessed through the same pointer. prepNewInstance is used to create a new rep. setSegment(String segment) is responsible for parsing the given segment string into the current rep of the underlying Segment. Similarly there is a subclass called GroupPointer that points to a Group slot. GroupPointer's setSegment(...) method just forwards the request to it's children (which are GroupPointers and SegmentPointers).

Method Detail

setSegment

public abstract int setSegment(String segment,
                               boolean correctOrder)
                        throws HL7Exception

Deprecated.

Parses the given String, which must contain a single traditionally encoded message segment, into the current repetition of the message Structure underlying this Pointer.

Parameters:

segment - the segment to parse

correctOrder - false if this segment should not actually be parsed because the current location precedes the location of a segment that has already been parsed. In this case, the return value should be either FILL_FAILED_FULL, FILL_FAILED_WRONG_SEGMENT, or FILL_FAILED_OUT_OF_ORDER, but the segment should not be parsed.

Returns:

an int indicating the success or flavours of failure of the request

Throws:

HL7Exception
