Interface IdentifierSegment

All Known Implementing Classes:
KeySegment, NameSegment

public interface IdentifierSegment

Component in a compound identifier. It is described by its name and how the name is quoted.

For example, the identifier [Store].USA.[New Mexico].&[45] has four segments:

QUOTED and UNQUOTED segments are represented using a NameSegment; KEY segments are represented using a KeySegment.

To parse an identifier into a list of segments, use the method IdentifierNode.parseIdentifier(String) and then call IdentifierNode.getSegmentList() on the resulting node.
