Constructor Detail

ModelGroupDefinition

public ModelGroupDefinition(EnterpriseConfiguration config,
                    SourceLocator locator)

Creates a new Model Group definition

Parameters:

config - the Configuration to which this Model Group definition belongs

locator - the source location of the model group definition

Method Detail

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

Parameters:

other - the model group that this one redefines

getNameCode

public int getNameCode()

getFingerprint

public int getFingerprint()

setNameCode

public void setNameCode(int nameCode)

getName

public String getName()

Returns the local part of the name of this named Group.

Returns:

the local name of this named Group.

getTargetNamespace

public String getTargetNamespace()

Returns the namespace URI of the name of this named Group.

Returns:

the namespace URI of this named Group: null if the group is in no namespace

isEmptiable

public boolean isEmptiable()
                    throws UnresolvedReferenceException

Determine if empty content is allowed

Specified by:

isEmptiable in class ModelGroup

Returns:

true if the content model of the model group allows empty content

Throws:

UnresolvedReferenceException - if the schema contains unresolved references to required components

isPointless

public boolean isPointless(ModelGroup container)

Test whether the compositor is pointless, as described in XML Schema Part 1 Schema Component Constraint: Particle Valid (Restriction)

Overrides:

isPointless in class ModelGroup

Parameters:

container - the particle that contains this model group definition

Returns:

true if this compositor is pointless

lookForCycles

public void lookForCycles(Stack references,
                 SchemaCompiler compiler)
                   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 ModelGroup

Parameters:

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.

compiler - used for error reporting

Throws:

SchemaException

UnresolvedReferenceException

validate

public boolean validate(SchemaCompiler compiler)
                 throws SchemaException

Checks the validity of this Model Group Definition.

Specified by:

validate in interface UserSchemaComponent

Overrides:

validate in class ModelGroup

Returns:

true when this Schema definition is valid, otherwise false.

Throws:

SchemaException

isSameGroup

public boolean isSameGroup(ModelGroupDefinition other)

Test whether this is the same group as another group. 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)

Parameters:

other - the other group

Returns:

true if the groups are the same

serialize

public void serialize(SchemaModelSerializer serializer)
               throws XPathException

Serialize the schema component

Specified by:

serialize in interface SerializableSchemaComponent

Overrides:

serialize in class ModelGroup

Parameters:

serializer - used to receive the serialized output

Throws:

XPathException - if serialization fails

getCompositorName

public String getCompositorName()

Description copied from class: ModelGroup

Get the name of the compositor used in this model group

Specified by:

getCompositorName in class ModelGroup

Returns:

one of "sequence", "choice", or "all"

getComponentAsFunction

public FunctionItem getComponentAsFunction()

Description copied from interface: SchemaComponent

Get the schema component in the form of a function item. This allows schema information to be made visible to XSLT or XQuery code. The function makes available the contents of the schema component as defined in the XSD specification. The function takes a string as argument representing a property name, and returns the corresponding property of the schema component. There is also a property "class" which returns the kind of schema component, for example "Attribute Declaration".

Specified by:

getComponentAsFunction in interface SchemaComponent

Overrides:

getComponentAsFunction in class ModelGroup

Returns:

the schema component represented as a function from property names to property values.
