Detailed Description

Identifiers manages the issuing of ids. Identifiers generates unique identifiers for AGSets, AGs, timelines, signals, annotations, and anchors. It also maintains Id to reference maps for AGSet, AG, Signal, Timeline, Annotation and Anchor, to speed up reference lookup.

Member Function Documentation

Id Identifiers::getNamespace (  const Id &    id )  [static]

Get the namespace of a given id. For example, the namespace of "TIMIT:AG122:Annotaion32" would be "TIMIT:AG122", and the namespace of "TIMIT:AG122" would be "TIMIT".

const Id Identifiers::new_id (  const Id &    id )  throw (AGException)

Try to register the given identifier. Parameters: id  existing identifier Returns: the identifier created Note: if the identifier already exists in issued then create a new identifier Exceptions: AGException  IF (the namespace of id is different from the one of the Identifiers)
