public abstract class PatternCollection

extends Pattern

This is an abstract class which represents aggregation of patterns. It consists of a list of patterns and its next method can be given different semantics to derive the pattern such as sequence , set etc.

Method Summary

ajanta.pattern.ItinEntry	currentEntry()
ajanta.pattern.ItinEntry	firstEntry() It finds the first ItinEntry in the PatternCollection and return it to the caller.
void	insert(ajanta.pattern.Pattern p) Add a new pattern to the list of patterns
protected void	join() It calls the join method of the Pattern at current position
void	print() It basically prints info about the pattern collection by recursively calling print method on each of its elements in the list and as well as its current pointer in the list

Method Detail

reset

protected void reset()

It sets the status of all the patterns in the list to NOTDONE

Specified by:

reset in class Pattern

insert

public void insert(ajanta.pattern.Pattern p)

Add a new pattern to the list of patterns

Parameters:

p - Pattern to be added

join

protected void join()

It calls the join method of the Pattern at current position

currentEntry

public ajanta.pattern.ItinEntry currentEntry()

Returns:

If the status of the PatternCollection is DONE then it returns null else it returns Pattern at current location

firstEntry

public ajanta.pattern.ItinEntry firstEntry()

It finds the first ItinEntry in the PatternCollection and return it to the caller. If the PatternCollection entries are themselves PatternCollection then it recursively call firstEntry on them till one finds a instance of ItinEntry.

print

public void print()

It basically prints info about the pattern collection by recursively calling print method on each of its elements in the list and as well as its current pointer in the list

Specified by:

print in class Pattern
