Class GlobalSchema

java.lang.Object
  org.inria.ns.reflex.processor.asl.GlobalSchema

All Implemented Interfaces:

Schema, Localizable

public class GlobalSchema
extends Object
implements Schema

A GlobalSchema holds all the schema instances of a given namespace URI.

A schema instance is looked up in the catalog if it is unknown of this global schema and if the expected resource has not been found ; the catalog to lookup is those of the processor instance used to build the global schema (adding a catalog can be done with ProcessorInstance.addCatalogReference(String)). In a way, a global schema contains several Schema bound to the same namespace URI, that can be DTD instances,

Active Schema instances, W3C XML Schema instances, Relax NG instances, TREX instances, or whatever can be compiled to a schema.

Constructor Detail

GlobalSchema

public GlobalSchema(ProcessorInstance pi,
                    String namespaceURI)

Create a new empty global schema.

Parameters:

pi - The non-null processor instance that creates this global schema.

namespaceURI - The namespaceURI of this global schema.

GlobalSchema

public GlobalSchema(ProcessorInstance pi,
                    Schema schema)

Create a new global schema.

Parameters:

pi - The non-null processor instance that creates this global schema.

schema - The first schema to store. This global schema endorse the same namespace URI of the first schema.

Method Detail

storeSchemaInstance

public void storeSchemaInstance(Schema schema)

Stores a schema instance in this global schema.

Parameters:

schema - The schema to store. null is ignored.

getTargetNamespaceURI

public String getTargetNamespaceURI()

Return the target namespace URI of this schema.

Specified by:

getTargetNamespaceURI in interface Schema

Returns:

The target namespace URI, that can be the empty string if no namespace URI has been defined.

See Also:

Schema.getTargetNamespaceURI()

getTypeDefinition

public Type getTypeDefinition(Type type)

Retrieve the next type that has the same name of the type given. If the type is not found in the known schema instances, the catalog may be involved to get more instances. The lookup starts from the schema that define the type given. Usefull for <asl:apply-definitions>

Parameters:

type - The non-null>/tt> type from which starting to search. Anonymous type are ignored.

Returns:

The type expected, or null.

getTypeDefinition

public Type getTypeDefinition(QName name)

Retrieve a type. If the type is not found in the known schema instances, the catalog may be involved to get more instances.

Specified by:

getTypeDefinition in interface Schema

Parameters:

name - The name of the type to retrieve.

Returns:

The type expected, or null.

See Also:

Schema.getTypeDefinition(org.inria.ns.reflex.xml.QName)

getTypeDefinition

public Type getTypeDefinition(String namespaceURI)

Return the fallback type.

Specified by:

getTypeDefinition in interface Schema

Parameters:

namespaceURI - The namespace URI of this global schema.

Returns:

The type expected, or null.

See Also:

Schema.getTypeDefinition(java.lang.String)

getElementDefinition

public ElementDefinition getElementDefinition(ElementDefinition elementDefinition)

Retrieve the next element definition that has the same name of the element definition given. If the element definition is not found in the known schema instances, the catalog may be involved to get more instances. The lookup starts from the schema that define the element definition given. Usefull for <asl:apply-definitions>

Parameters:

elementDefinition - The non-null>/tt> element definition from which starting to search.

Returns:

The element definition expected, or null.

getElementDefinition

public ElementDefinition getElementDefinition(QName name)
