ComplexType definition.
ComplexTypeExp holds an expression (as a ReferenceExp) that matches to
this type itself.
the
body
field contains the expression that exactly matches
to the declared content model (without any substitutable types).
the
exp
field contains the reference to the body field,
if this complex type is not abstract. If abstract, then nullSet is set.
You shouldn't directly manipulate the exp field. Instead, you should use
the
setAbstract(boolean)
method to do it.
Note: The runtime type substitution
(the use of
xsi:type
attribute)
is implemented at the VGM layer. Therefore, AGMs of XML Schema does
NOT
precisely represent what are actually allowed and what are not.
Complex Type Definition Schema Component Properties
This table shows the mapping between
"complex type definition schema component properties"
(which is defined in the spec) and corresponding method/field of this class.
Property of the spec | method/field of this class |
name
|
The ReferenceExp.name field.
|
target namespace
|
the getTargetNamespace() method.
|
abstract
|
the isAbstract() method.
|
base type definition
|
simpleBaseType or complexBaseType field,
depending on whether the base type is a simple type or a complex type.
|
derivation method
|
the derivationMethod field.
|
final
|
the finalValue field.
|
prohibited substitutions
|
the block field.
|
attribtue uses attribute wildcard content type
|
Not directly accessible. Can be found by walking
the children of the body field.
|
annotation
|
Unaccessible. This information is removed during the parsing phase.
|
Abstractness
The
exp
field and the
self
field are very similar.
In fact, the only difference is that the former is affected by the abstract
property, while the latter isn't.
So if it has to be affected by the
abstract property (like referencing a complex type as the element body),
you should use the
exp
field.
If you don't want to be affected by the abstract property
(like referencing a complex type as the base type of another complex type),
then you should refer to the
body
field.
attWildcard
public final ReferenceExp attWildcard
attribute wildcard as an expression.
block
public int block
The
block property of this schema component, implemented as a bit field.
0, RESTRICTION, EXTENSION, or (RESTRICTION|EXTENSION).
body
public final ReferenceExp body
actual content model definition + attribute uses.
complexBaseType
public ComplexTypeExp complexBaseType
base type of this complex type.
Either baseComplexType field or baseSimpleType field is set.
If the base type is
ur-type, both fields are set to null.
derivationMethod
public int derivationMethod
the derivation method used to derive this complex type from the base type.
Either RESTRICTION or EXTENSION.
finalValue
public int finalValue
The
final property of this schema component, implemented as a bit field.
0, RESTRICTION, EXTENSION, or (RESTRICTION|EXTENSION).
parent
public final XMLSchemaSchema parent
parent XMLSchemaSchema object to which this object belongs.
simpleBaseType
public XSDatatypeExp simpleBaseType
base type of this complex type.
wildcard
public AttributeWildcard wildcard
Attribute wild card constraint.
Due to the nasty definition of the interaction between attribute wildcards,
we cannot add the expression for validating wildcard until the very last moment.
Until the wrap-up phase of the schema parsing, this field will contain
the "local wildcard definition." In the wrap-up phase, this field is replaced
by the "complete wildcard definition."
getBlock
public int getBlock()
Gets the value of the block constraint.
SimpleTypeExp always returns 0 because it doesn't have the block constraint.
- getBlock in interface XMLSchemaTypeExp
getTargetNamespace
public final String getTargetNamespace()
gets the target namespace property of this component as
specified in the spec.
If the property is
absent, then this method returns the empty string.
This method is just a shortcut for
parent.targetNamespace
.
isAbstract
public boolean isAbstract()
checks if this complex type is abstract.
This method corresponds to the abstract property of
the complex type declaration schema component.
- true if this method is abstract. Flase if not.
isDefined
public boolean isDefined()
implementation detail.
A ComplexTypeDecl is properly defined if its self is defined.
Note that the default implementation of the isDefined method doesn't
work for this class because the exp field is set by the constructor.
- isDefined in interface ReferenceExp
isDerivedTypeOf
public boolean isDerivedTypeOf(XSDatatype baseType,
int constraint)
isDerivedTypeOf
public boolean isDerivedTypeOf(ComplexTypeExp baseType,
int constraint)
Checks if this type is a derived type of the specified type.
This method is an implementation of
"Type Derivation OK (Complex)" test
of the spec.
If you are not familiar with the abovementioned part of the spec,
don't use this method. This method probably won't give you
what you expected.
- true if the specified type is "validly derived" from this type.
false if not.
isDerivedTypeOf
public boolean isDerivedTypeOf(XMLSchemaTypeExp exp,
int constraint)
setAbstract
public void setAbstract(boolean isAbstract)
