//
|
|
// Date Name Description
|
|
// 2/5/97 aliu Added streamIn and streamOut methods to EntryPair,
|
|
// VectorOfInt, VectorOfPToExpandTable, VectorOfPToContractElement,
|
|
// VectorOfPToContractTable. These are used by TableCollation
|
|
// streamIn and streamOut methods.
|
|
// 3/5/97 aliu Made VectorOfPointersToPatternEntry::at() inline.
|
|
// 5/07/97 helena Added isBogus().
|
|
// 6/18/97 helena Added VectorOfPointer for queue-up extension list in
|
|
// MergeCollation.
|
|
// 8/18/97 helena Added internal API documentation. Note. All the VectorOfXXX
|
|
// interface is about the same. The internal API docs will be
|
|
// added to only the first version and additional description
|
|
// will be added where necessary.
|
|
// 8/04/98 erm Added fwd member to EntryPair.
