Constructor Detail

ModelGroupDefinition

public ModelGroupDefinition(PreparedSchema schema,
                            javax.xml.transform.SourceLocator locator)

Creates a new Group definition

Parameters:

schema - the XML Schema to which this Group belongs

Method Detail

setName

public void setName(java.lang.String name)

Set the name of the group

setRedefinedModelGroupDefinition

public void setRedefinedModelGroupDefinition(ModelGroupDefinition other)

Set the model group definition that this one redefines. Only set if this is a redefining model group that does not contain a self-reference; in this case validate() must check that it is a valid refinement

getContentModelGroup

public Compositor getContentModelGroup()

Returns the ContentModelGroup for this group Only used for a element

Returns:

the ContentModelGroup for this group

getFingerprint

public int getFingerprint()

setFingerprint

public void setFingerprint(int fingerprint)

getName

public java.lang.String getName()

Returns the name of this Group.

Returns:

the name of this Group.

isEmptiable

public boolean isEmptiable()
                    throws UnresolvedReferenceException

Determine if empty content is allowed

Throws:

UnresolvedReferenceException

lookForCycles

public void lookForCycles(PreparedSchema schema,
                          java.util.Stack references)
                   throws SchemaException,
                          UnresolvedReferenceException

This method is called to look for cycles. The object implementing this method is required (a) to raise an exception if the object itself appears in the list of references, (b) to add itself to the list of references, and (c) to call the lookForCycles method on all the objects that it references.

Specified by:

lookForCycles in interface UserSchemaComponent

Overrides:

lookForCycles in class Compositor

Parameters:

schema -

references - A list of objects that contain direct or indirect references to this object, and that must therefore not be referred to from this object.

Throws:

SchemaException

UnresolvedReferenceException

validate

public boolean validate(PreparedSchema schema)
                 throws SchemaException,
                        ValidationException

Checks the validity of this Schema definition.

Specified by:

validate in interface UserSchemaComponent

Overrides:

validate in class Compositor

Throws:

SchemaException

ValidationException

isSameGroup

public boolean isSameGroup(ModelGroupDefinition other)

Test whether this is the same type as another type. They are considered to be the same type if they are derived from the same type definition in the original XML representation (which can happen when there are multiple includes of the same file)
