Interface ComplexType

All Superinterfaces:
  SchemaComponent, SchemaType, java.io.Serializable

All Known Implementing Classes:
  AnyType, Untyped

public interface ComplexType
extends SchemaType

A complex type as defined in XML Schema: either a user-defined complex type, or xs:anyType. In the non-schema-aware version of the Saxon product, the only complex type encountered is xs:anyType.

Method Detail

### isAbstract

    public boolean isAbstract()

  Test whether this complex type has been marked as abstract.

  Returns:
    true if this complex type is abstract.

### isComplexContent

    public boolean isComplexContent()

  Test whether this complex type has complex content

  Returns:
    true if this complex type has a complex content model, false if it has a simple content model

### isSimpleContent

    public boolean isSimpleContent()

  Test whether this complexType has simple content

  Returns:
    true if this complex type has a simple content model, false if it has a complex content model

### isAllContent

    public boolean isAllContent()

  Test whether this complex type has "all" content, that is, a content model using an xs:all compositor

### getSimpleContentType

    public SimpleType getSimpleContentType()

  Get the simple content type

  Returns:
    For a complex type with simple content, returns the simple type of the content. Otherwise, returns null.

### isRestricted

    public boolean isRestricted()

  Test whether this complex type is derived by restriction

  Returns:
    true if this complex type is derived by restriction

### isEmptyContent

    public boolean isEmptyContent()

  Test whether the content model of this complex type is empty

  Returns:
    true if the content model is defined as empty

### isEmptiable

    public boolean isEmptiable()
                        throws SchemaException,
                               ValidationException

  Test whether the content model of this complex type allows empty content

  Returns:
    true if empty content is valid
  Throws:
    `SchemaException`
    `ValidationException`

### isMixedContent

    public boolean isMixedContent()

  Test whether this complex type allows mixed content

  Returns:
    true if mixed content is allowed

### subsumes

    public java.lang.String subsumes(ComplexType sub)
                              throws ValidationException

  Test whether this complex type subsumes another complex type. The algorithm used is as published by Thompson and Tobin, XML Europe 2003.

  Parameters:
    `sub` - the other type (the type that is derived by restriction, validly or otherwise)
  Returns:
    null indicating that this type does indeed subsume the other; or a string indicating why it doesn't.
  Throws:
    `ValidationException`

### getElementParticleType

    public SchemaType getElementParticleType(int fingerprint)
                                      throws SchemaException,
                                             ValidationException

  Find an element particle within this complex type definition having a given element name (identified by fingerprint), and return the schema type associated with that element particle. If there is no such particle, return null. If the fingerprint matches an element wildcard, return the type of the global element declaration with the given name if one exists, or AnyType if none exists and lax validation is permitted by the wildcard.

  Parameters:
    `fingerprint` - Identifies the name of the child element within this content model
  Throws:
    `SchemaException`
    `ValidationException`

### getElementParticleCardinality

    public int getElementParticleCardinality(int fingerprint)
                                      throws SchemaException,
                                             ValidationException

  Find an element particle within this complex type definition having a given element name (identified by fingerprint), and return the cardinality associated with that element particle, that is, the number of times the element can occur within this complex type. The value is one of `StaticProperty.EXACTLY_ONE`, `StaticProperty.ALLOWS_ZERO_OR_ONE`, `StaticProperty.ALLOWS_ZERO_OR_MORE`, `StaticProperty.ALLOWS_ONE_OR_MORE`, If there is no such particle, return zero.

  Parameters:
    `fingerprint` - Identifies the name of the child element within this content model
  Throws:
    `SchemaException`
    `ValidationException`

### getAttributeUseType

    public SchemaType getAttributeUseType(int fingerprint)
                                   throws SchemaException,
                                          ValidationException

  Find an attribute use within this complex type definition having a given attribute name (identified by fingerprint), and return the schema type associated with that attribute. If there is no such attribute use, return null. If the fingerprint matches an attribute wildcard, return the type of the global attribute declaration with the given name if one exists, or AnySimpleType if none exists and lax validation is permitted by the wildcard.

  If there are types derived from this type by extension, search those too.

  Parameters:
    `fingerprint` - Identifies the name of the child element within this content model
  Throws:
    `SchemaException`
    `ValidationException`
