|

| 17 | * Clique is a class pattern marking classes which
|
|---|
| 18 | * create only a few instances, generally accessible through
|
|---|
| 19 | * some global mechanism, and every single
|
|---|
| 20 | * one of which gets its own distinct setup(...) call. Cliques should
|
|---|
| 21 | * <b>not</b> be Cloneable, but they are Serializable.
|
|---|
| 22 | *
|
|---|
| 23 | * <p>All Cliques presently in ECJ rely on a central repository which
|
|---|
| 24 | * stores members of that Clique for easy access by various objects.
|
|---|
| 25 | * This repository typically includes a hashtable of the Clique members,
|
|---|
| 26 | * plus perhaps one or more arrays of the members stored in different
|
|---|
| 27 | * fashions. Originally these central repositories were stored as static
|
|---|
| 28 | * members of the Clique class; but as of ECJ 13 they have been moved
|
|---|
| 29 | * to be instance variables of certain Initializers. For example,
|
|---|
| 30 | * GPInitializer holds the repositories for the GPFunctionSet, GPType,
|
|---|
| 31 | * GPNodeConstraints, and GPTreeConstraints cliques. Likewise,
|
|---|
| 32 | * RuleInitializer holds the repository for the RuleConstraints clique.
|
|---|
| 33 | *
|
|---|
| 34 | * <p>This change was made to facilitate making ECJ modular; we had to remove
|
|---|
| 35 | * all non-final static members. If you make your own Clique, its repository
|
|---|
| 36 | * (if you have one) doesn't have to be in an Initializer, but it's a
|
|---|
| 37 | * convenient location.
