Class ComplexTypeExp

All Implemented Interfaces:
Serializable

public class ComplexTypeExp extends XMLSchemaTypeExp
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.

  • Field Details

    • body

      public final ReferenceExp body
      actual content model definition + attribute uses.
    • attWildcard

      public final ReferenceExp attWildcard
      attribute wildcard as an expression.
    • parent

      public final XMLSchemaSchema parent
      parent XMLSchemaSchema object to which this object belongs.
    • 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."

    • 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.
      See Also:
    • simpleBaseType

      public XSDatatypeExp simpleBaseType
      base type of this complex type.
      See Also:
    • derivationMethod

      public int derivationMethod
      the derivation method used to derive this complex type from the base type. Either RESTRICTION or EXTENSION.
      See Also:
    • finalValue

      public int finalValue
      The final property of this schema component, implemented as a bit field.

      0, RESTRICTION, EXTENSION, or (RESTRICTION|EXTENSION).

    • block

      public int block
      The block property of this schema component, implemented as a bit field.

      0, RESTRICTION, EXTENSION, or (RESTRICTION|EXTENSION).

    • serialVersionUID

      private static final long serialVersionUID
      See Also:
  • Constructor Details

  • Method Details

    • getAttributeWildcard

      public AttributeWildcard getAttributeWildcard()
    • setAttributeWildcard

      public void setAttributeWildcard(AttributeWildcard local)
    • 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.

      Returns:
      true if this method is abstract. Flase if not.
    • setAbstract

      public void setAbstract(boolean isAbstract)
    • 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.

      Parameters:
      constraint - A bit field that represents the restricted derivation. This field must consists of bitwise and of XMLSchemaTypeExp.EXTENSION or XMLSchemaTypeExp.RESTRICTION.
      Returns:
      true if the specified type is "validly derived" from this type. false if not.
    • isDerivedTypeOf

      public boolean isDerivedTypeOf(XSDatatype baseType, int constraint)
      See Also:
    • isDerivedTypeOf

      public boolean isDerivedTypeOf(XMLSchemaTypeExp exp, int constraint)
    • getBlock

      public int getBlock()
      Gets the value of the block constraint. SimpleTypeExp always returns 0 because it doesn't have the block constraint.
      Specified by:
      getBlock in class XMLSchemaTypeExp
    • getClone

      public RedefinableExp getClone()
      clone this object.
      Specified by:
      getClone in class RedefinableExp
    • redefine

      public void redefine(RedefinableExp _rhs)
      Description copied from class: RedefinableExp
      assigns contents of rhs to this object. rhs and this object must be the same runtime type, and they must have the same name. this method redefines this object by the given component. derived class should override this method and copy necessary fields, should it necessary.
      Overrides:
      redefine in class RedefinableExp
    • 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.
      Overrides:
      isDefined in class ReferenceExp
