Constructor Detail

XSModelImpl

public XSModelImpl(SchemaGrammar[] grammars)

Construct an XSModelImpl, by storing some grammars and grammars imported by them to this object.

Parameters:

grammars - the array of schema grammars

Method Detail

getNamespaces

public org.apache.xerces.xs.StringList getNamespaces()

Convenience method. Returns a list of all namespaces that belong to this schema.

Specified by:

getNamespaces in interface org.apache.xerces.xs.XSModel

Returns:

A list of all namespaces that belong to this schema or null if all components don't have a targetNamespace.

getNamespaceItems

public org.apache.xerces.xs.XSNamespaceItemList getNamespaceItems()

Description copied from interface: org.apache.xerces.xs.XSModel

A set of namespace schema information information items (of type XSNamespaceItem), one for each namespace name which appears as the target namespace of any schema component in the schema used for that assessment, and one for absent if any schema component in the schema had no target namespace. For more information see schema information.

Specified by:

getNamespaceItems in interface org.apache.xerces.xs.XSModel

getComponents

public org.apache.xerces.xs.XSNamedMap getComponents(short objectType)

Returns a list of top-level components, i.e. element declarations, attribute declarations, etc.

Specified by:

getComponents in interface org.apache.xerces.xs.XSModel

Parameters:

objectType - The type of the declaration, i.e. ELEMENT_DECLARATION. Note that XSTypeDefinition.SIMPLE_TYPE and XSTypeDefinition.COMPLEX_TYPE can also be used as the objectType to retrieve only complex types or simple types, instead of all types.

Returns:

A list of top-level definitions of the specified type in objectType or an empty XSNamedMap if no such definitions exist.

getComponentsByNamespace

public org.apache.xerces.xs.XSNamedMap getComponentsByNamespace(short objectType,
                                                                java.lang.String namespace)

Convenience method. Returns a list of top-level component declarations that are defined within the specified namespace, i.e. element declarations, attribute declarations, etc.

Specified by:

getComponentsByNamespace in interface org.apache.xerces.xs.XSModel

Parameters:

objectType - The type of the declaration, i.e. ELEMENT_DECLARATION.

namespace - The namespace to which the declaration belongs or null (for components with no target namespace).

Returns:

A list of top-level definitions of the specified type in objectType and defined in the specified namespace or an empty XSNamedMap.

getTypeDefinition

                                                               java.lang.String namespace)

Convenience method. Returns a top-level simple or complex type definition.

Specified by:

getTypeDefinition in interface org.apache.xerces.xs.XSModel

Parameters:

getAnnotations in interface org.apache.xerces.xs.XSModel

hasIDConstraints

public boolean hasIDConstraints()

REVISIT: to expose identity constraints from XSModel. For now, we only expose whether there are any IDCs. We also need to add these methods to the public XSModel interface.

getSubstitutionGroup

public org.apache.xerces.xs.XSObjectList getSubstitutionGroup(org.apache.xerces.xs.XSElementDeclaration head)

REVISIT: to expose substitution group of a given element. We need to add this to the XSModel interface.
