Method Summary

Modifier and Type	Method	Description
boolean	canBeSubstitutedBy(XSElementDecl e)	Returns true if this element declaration can be validly substituted by the given declaration.
XmlString	getDefaultValue()
XmlString	getFixedValue()
Boolean	getForm()	Used for javadoc schema generation
List<XSIdentityConstraint>	getIdentityConstraints()	Returns all the XSIdentityConstraints in this element decl.
XSElementDecl	getSubstAffiliation()	Gets the substitution head of this element, if any.
Set<? extends XSElementDecl>	getSubstitutables()	Returns the element declarations that can substitute this element.
XSType	getType()	Gets the type of this element declaration.
boolean	isAbstract()
boolean	isNillable()
boolean	isSubstitutionDisallowed(int method)	Checks the diallowed substitution property of the schema component.
boolean	isSubstitutionExcluded(int method)	Checks the substitution excluded property of the schema component.
XSElementDecl[]	listSubstitutables()	Deprecated. this method allocates a new array every time, so it could be inefficient when working with a large schema.

Method Detail

getType

XSType getType()

Gets the type of this element declaration.

Returns:

always non-null.

isNillable

boolean isNillable()

getSubstAffiliation

XSElementDecl getSubstAffiliation()

Gets the substitution head of this element, if any. Otherwise null.

getIdentityConstraints

List<XSIdentityConstraint> getIdentityConstraints()

Returns all the XSIdentityConstraints in this element decl.

Returns:

never null, but can be empty.

isSubstitutionExcluded

boolean isSubstitutionExcluded(int method)

Checks the substitution excluded property of the schema component. IOW, this checks the value of the final attribute (plus finalDefault).

Parameters:

method - Possible values are XSType.EXTENSION or XSType.RESTRICTION.

isSubstitutionDisallowed

boolean isSubstitutionDisallowed(int method)

Checks the diallowed substitution property of the schema component. IOW, this checks the value of the block attribute (plus blockDefault).

Parameters:

method - Possible values are XSType.EXTENSION, XSType.RESTRICTION, or XSType.SUBSTITUTION

isAbstract

boolean isAbstract()

listSubstitutables

@Deprecated
XSElementDecl[] listSubstitutables()

Deprecated.

this method allocates a new array every time, so it could be inefficient when working with a large schema. Use getSubstitutables() instead.

Returns the element declarations that can substitute this element.

IOW, this set returns all the element decls that satisfies the "Substitution Group OK" constraint.

Returns:

nun-null valid array. The return value always contains this element decl itself.

getSubstitutables

Set<? extends XSElementDecl> getSubstitutables()

Returns the element declarations that can substitute this element.

IOW, this set returns all the element decls that satisfies the "Substitution Group OK" constraint.

Note that the above clause does NOT check for abstract elements. So abstract elements may still show up in the returned set.

Returns:

nun-null unmodifiable list. The returned list always contains this element decl itself.

canBeSubstitutedBy

boolean canBeSubstitutedBy(XSElementDecl e)

Returns true if this element declaration can be validly substituted by the given declaration.

Just a short cut of getSubstitutables().contain(e);

getDefaultValue

XmlString getDefaultValue()

getFixedValue

XmlString getFixedValue()

getForm

Boolean getForm()

Used for javadoc schema generation

Returns:

null if form attribute not present, true if form attribute present and set to qualified, false if form attribute present and set to unqualified.
