|
| public boolean | containsGrammar(com.sun.org.apache.xerces.internal.xni.grammars.XMLGrammarDescription desc)Returns true if the grammar pool contains a grammar associated
to the specified grammar description. Currently, the root element name
is used as the key for DTD grammars and the target namespace is used
as the key for Schema grammars.
synchronized (fGrammars) {
int hash = hashCode(desc);
int index = (hash & 0x7FFFFFFF) % fGrammars.length;
for (Entry entry = fGrammars[index] ; entry != null ; entry = entry.next) {

}
|
| public boolean | equals(com.sun.org.apache.xerces.internal.xni.grammars.XMLGrammarDescription desc1, com.sun.org.apache.xerces.internal.xni.grammars.XMLGrammarDescription desc2)This method checks whether two grammars are the same. Currently, we compare
the root element names for DTD grammars and the target namespaces for Schema grammars.
The application can override this behaviour and add its own logic.
return desc1.equals(desc2);
|
| public com.sun.org.apache.xerces.internal.xni.grammars.Grammar | getGrammar(com.sun.org.apache.xerces.internal.xni.grammars.XMLGrammarDescription desc)Returns the grammar associated to the specified grammar description.
Currently, the root element name is used as the key for DTD grammars
and the target namespace is used as the key for Schema grammars.
synchronized (fGrammars) {
int hash = hashCode(desc);
int index = (hash & 0x7FFFFFFF) % fGrammars.length;
for (Entry entry = fGrammars[index] ; entry != null ; entry = entry.next) {

|
| public int | hashCode(com.sun.org.apache.xerces.internal.xni.grammars.XMLGrammarDescription desc)Returns the hash code value for the given grammar description.

| public void | lockPool()
fPoolIsLocked = true;
|
| public void | putGrammar(com.sun.org.apache.xerces.internal.xni.grammars.Grammar grammar)Puts the specified grammar into the grammar pool and associates it to
its root element name or its target namespace.

XMLGrammarDescription desc = grammar.getGrammarDescription();
int hash = hashCode(desc);

| public com.sun.org.apache.xerces.internal.xni.grammars.Grammar | removeGrammar(com.sun.org.apache.xerces.internal.xni.grammars.XMLGrammarDescription desc)Removes the grammar associated to the specified grammar description from the
grammar pool and returns the removed grammar. Currently, the root element name
is used as the key for DTD grammars and the target namespace is used
as the key for Schema grammars.
