Interface ComponentWithValueConstraint

All Known Implementing Classes:

AttributeDecl, AttributeUse, ElementDecl

public interface ComponentWithValueConstraint

Interface for Element Declaration, Attribute Declaration and Attribute Use, created because they share common functionality for handling fixed and default values

Method Summary

Modifier and Type	Method and Description
default AtomicSequence	getDefaultValue() Gets the default value, as a typed value.
default ValueConstraint	getDefaultValueConstraint()
default java.lang.String	getDefaultValueLexicalForm() Returns the lexical form of the default value of this component
default AtomicSequence	getFixedValue() Returns the fixed value of this component.
default ValueConstraint	getFixedValueConstraint()
default java.lang.String	getFixedValueLexicalForm() Returns the lexical form of the fixed value of this attribute use.
NamespaceResolver	getNamespaceResolver() Get the namespace resolver used when the fixed or value constraints include lexical QNames
ValueConstraint	getValueConstraint()
default Sequence<?>	getValueConstraintAsFunction(ComponentWithValueConstraint att) For use with the saxon:schema extension function, return the value constraint in the form of a function
void	setValueConstraint(ValueConstraint vc)

Method Detail

getValueConstraint

ValueConstraint getValueConstraint()

setValueConstraint

void setValueConstraint(ValueConstraint vc)

getFixedValueConstraint

default ValueConstraint getFixedValueConstraint()

getDefaultValueConstraint

default ValueConstraint getDefaultValueConstraint()

getValueConstraintAsFunction

default Sequence<?> getValueConstraintAsFunction(ComponentWithValueConstraint att)

For use with the saxon:schema extension function, return the value constraint in the form of a function

Parameters:

att - the component having the value constraint

Returns:

a function whose result gives details of the value constraint

getFixedValueLexicalForm

default java.lang.String getFixedValueLexicalForm()

Returns the lexical form of the fixed value of this attribute use.

Returns:

the fixed value defined by this attribute use, or null if no fixed value was specified. The value that is returned is the value as written in the schema document with whitespace normalization applied as defined by the whiteSpace facet.

getFixedValue

default AtomicSequence getFixedValue()

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

Returns:

the fixed value defined by this attribute declaration, element declaration, or attribute use, 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.

getDefaultValueLexicalForm

default java.lang.String getDefaultValueLexicalForm()

Returns the lexical form of the default value of this component

Returns:

the default value defined by this component, or null if no default was specified. The value returned is the value after whitespace normalization is applied to the value as written in the source schema.

getDefaultValue

default AtomicSequence getDefaultValue()

Gets the default value, as a typed value.

Returns:

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

getNamespaceResolver

NamespaceResolver getNamespaceResolver()

Get the namespace resolver used when the fixed or value constraints include lexical QNames

Returns:

the namespace resolver for lexical QNames
