public final class AttributeDecl
extends SchemaStructure
implements UserSchemaComponent, SerializableSchemaComponent, SchemaDeclaration

An XML Schema Attribute Declaration. This includes global attribute declarations, local attribute declarations, and "attribute uses". It corresponds to either (a) an attribute declaration schema component for a global attribute, or (b) an attribute declaration schema component for a local attribute, plus an attribute use referencing that attribute declaration, or (c) an attribute use referencing a global attribute declaration.

Constructor Detail

AttributeDecl

public AttributeDecl(EnterpriseConfiguration config,
             boolean global)

Creates a new AttrDecl in the given schema. For system use only.

Parameters:

config - the configuration that contains the new attrDecl

global - true if the attribute declaration is global

Method Detail

isGlobal

public boolean isGlobal()

Determine whether this attribute declaration is global. This represents one aspect of the {scope} property defined in the schema data model.

Returns:

true if the attribute declaration is global, false if it is local

setContainingComplexType

public void setContainingComplexType(UserComplexType type)

Sets the containing complex type definition. For internal use only.

Parameters:

type - the containing complex type

getContainingComplexType

public UserComplexType getContainingComplexType()

Get the containing complex type. This represents one aspect of the {scope} property defined in the schema component model. If the attribute is a local attribute declaration and is defined as part of a complex type (and not as part of a named attribute group), returns the complex type definition. Otherwise, returns null.

Returns:

the containing complex type definition if there is one, otherwise null

setContainingAttributeGroup

public void setContainingAttributeGroup(AttributeGroupDecl type)

Sets the containing attribute group definition. For internal use only.

Parameters:

type - the containing attribute group

getContainingAttributeGroup

public AttributeGroupDecl getContainingAttributeGroup()

Get the containing attribute group. This represents one aspect of the {scope} property defined in the schema component model. If the attribute is a local attribute declaration and is defined as part of an attribute group (and not as part of a complex type), returns the attribute group. Otherwise, returns null.

Returns:

the containing attribute group if there is one, otherwise null

getName

public String getName()

Get the local name of this Attribute Declaration. This corresponds to the {name} property as defined in the schema component model.

Returns:

the local name of the attribute

getTargetNamespace

public String getTargetNamespace()

Get the namespace URI of this element declaration. This corresponds to the {targetNamespace} property defined in the schema component model.

Returns:

the target namespace URI

getDisplayName

public String getDisplayName()

Returns the name of the attribute defined by this AttributeDecl. This is used only for diagnostic display purposes

Returns:

the name of the attribute as a lexical QName.

setAttributeName

public void setAttributeName(StructuredQName attributeName,
                    int fingerprint)

Set the attribute name. For internal use only.

Parameters:

attributeName - the attribute name.

setAttributeName

public void setAttributeName(StructuredQName attributeName)

Set the attribute name. For internal use only.

Parameters:

MissingComponentException - if the reference from the attribute declaration to its type has not been resolved

getType

public SimpleType getType()
                   throws MissingComponentException

Get the type of this attribute declaration. This corresponds to the {typeDefinition} property defined in the schema component model

Specified by:

getType in interface SchemaDeclaration

Returns:

the type of this attribute. The returned SchemaType will always be an instanceof SimpleType

Throws:

MissingComponentException

getDefaultValue

public String getDefaultValue()

Returns the default value of this attribute declaration. This corresponds to one aspect of the {valueConstraint} property defined in the schema component model.

Returns:

the default value defined by this attribute declaration, or null if no default was specified. The default value is always maintained as a string, in the form supplied in the original schema document.

getFixedValue

public AtomicSequence getFixedValue()

Returns the fixed value of this attribute declaration. This corresponds to one aspect of the {valueConstraint} property defined in the schema component model.

Returns:

the fixed value defined by this attribute declaration, or null if no fixed value was specified. Once the schema has been compiled this will be the correctly-typed value; until then it will be the string value as specified in the source schema document.

setSimpleType

public void setSimpleType(SimpleType simpleType)

Sets the SimpleType for this attribute declaration. For internal use only.

Parameters:

simpleType - the SimpleType for this attribute declaration

setDefaultValue

public void setDefaultValue(String value)

Sets the default value. For internal use only.

Parameters:

value - the default value

setFixedValue

public void setFixedValue(AtomicSequence value)

Sets the fixed value. For internal use only.

Parameters:

value - the fixed value. This will initially be saved as an UntypedAtomicValue; later, when the type is known, it will be converted to the correct type

setNamespaceResolver

public void setNamespaceResolver(NamespaceResolver resolver)

Set the namespace resolver for resolving QName-valued fixed and default values

Parameters:

resolver - the namespace resolver

makeSchemaNodeTest

Parameters:

value - the value to be tested

resolver - Namespace resolver for use if the value is namespace-sensitive (QName or NOTATION)

Returns:

true if it matches (or if there is no fixed value), false otherwise

Throws:

ValidationException - if the value is not valid for this type

MissingComponentException

isSameDeclaration

MissingComponentException - if the component cannot be serialized because it contains dangling references

XPathException - if serialization fails

getComponentAsFunction

public Function 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

Returns:

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