Constructor Summary | |
---|---|
AttributeGroupReference(EnterpriseConfiguration config,
int fingerprint)
Creates a new AttributeGroup reference |
Method Summary | |
---|---|
void |
elaborate(SchemaCompiler compiler)
Elaborate the schema component: after reloading a serialized schema component model, this expands the component with derived information needed during validation episodes. |
boolean |
fixup(SchemaCompiler compiler)
Fix up references to other elements in the schema. |
AttributeWildcard |
getAttributeWildcard(SchemaCompiler compiler)
Returns the attribute wildcard in the referenced attribute group, if any. |
int |
getFingerprint()
Get the fingerprint of the target of this reference |
int |
getSymbolSpace()
Get the symbol space of the target of this reference |
SchemaComponent |
getTarget()
Resolves the attribute group reference Note this method doesn't bind irrevocably to the target attribute group declaration, because this may change following a redefine. |
boolean |
isResolved()
Determine whether this reference has been resolved |
void |
lookForCycles(Stack references,
SchemaCompiler compiler)
Check for cycles in the attribute group. |
void |
setFingerprint(int fingerprint)
Set the fingerprint of the target of this reference |
void |
tryToResolve(SchemaCompiler compiler)
Attempt to resolve this reference using the groups defined in a given schema. |
boolean |
validate(SchemaCompiler compiler)
Checks the validity of this Schema component. |
