All Implemented Interfaces:

SerializableSchemaComponent, UserSchemaComponent, Serializable, SourceLocator, SchemaComponent, SchemaDeclaration

public final class AttributeDecl
extends SchemaStructure
implements UserSchemaComponent, 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(PreparedSchema schema,
                     boolean global)

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

Parameters:

schema - the schema 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.

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

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

getNamespace

public String getNamespace()

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

Returns:

the namespace URI part of the name of the attribute

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.

setNameCode

public void setNameCode(int nameCode)

Set the fingerprint for this attribute name. For internal use only.

getFingerprint

public int getFingerprint()

Gets the fingerprint of this attribute name

Returns:

the fingerprint of the attribute name in the NamePool

getNameCode

public int getNameCode()

Get the nameCode of the name of this attribute declaration in the namePool

Returns:

the nameCode of the attribute name

getSimpleType

public SimpleType getSimpleType()
                         throws UnresolvedReferenceException

Get the type associated with this Attribute Declaration.

Returns:

the type of this attribute.

Throws:

UnresolvedReferenceException

getType

public SchemaType getType()
                   throws UnresolvedReferenceException

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:

UnresolvedReferenceException

setTypeFingerprint

public void setTypeFingerprint(int fingerprint)

Set the namepool fingerprint of the name of the attribute's type.

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 Value 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.

setFixedValue

public void setFixedValue(Value value)

Sets the FIXED value. For internal use only.

setNamespaceResolver

public void setNamespaceResolver(NamespaceResolver resolver)

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

makeSchemaNodeTest

public NodeTest makeSchemaNodeTest()

Create a NodeTest that implements the semantics of schema-element(name) or schema-attribute(name) applied to this element or attribute declaration.

Specified by:

makeSchemaNodeTest in interface SchemaDeclaration

fixup

public boolean fixup(SchemaCompiler compiler)
              throws SchemaException,
                     UnresolvedReferenceException

Check references from this component to other components

Specified by:

fixup in interface UserSchemaComponent

Parameters:

compiler -

Returns:

true if all is well, false if errors found

Throws:

SchemaException

UnresolvedReferenceException

validate

public boolean validate(SchemaCompiler compiler)
                 throws SchemaException,
                        ValidationException

Checks the validity of this Attribute declaration

Specified by:

validate in interface UserSchemaComponent

Returns:

true when this Schema definition is valid, otherwise false.

Throws:

SchemaException - if the error listener decides an error is fatal

ValidationException

testFixedValue

                              NamespaceResolver resolver)
                       throws ValidationException

Test a value against the fixed value. This tests both against the fixed value for this attribute use, and the fixed value of the corresponding attribute declaration (which must be equivalent if they are both present).

Parameters:

value - the value to be tested

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

isSameDeclaration

public boolean isSameDeclaration(AttributeDecl 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)
