Interface ComplexType

All Superinterfaces:
SchemaComponent, SchemaType, 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, or xs:untyped. In the non-schema-aware version of the Saxon product, the only complex type encountered is xs:untyped.
  • Method Details

    • isAbstract

      boolean isAbstract()
      Test whether this complex type has been marked as abstract. This corresponds to the {abstract} property in the schema component model.
      Returns:
      true if this complex type is abstract.
    • isComplexContent

      boolean isComplexContent()
      Test whether this complex type has complex content. This represents one aspect of the {content type} property in the schema component model.
      Returns:
      true if this complex type has a complex content model, false if it has a simple content model
    • isSimpleContent

      boolean isSimpleContent()
      Test whether this complexType has simple content. This represents one aspect of the {content type} property in the schema component model.
      Returns:
      true if this complex type has a simple content model, false if it has a complex content model
    • isAllContent

      boolean isAllContent()
      Test whether this complex type has "all" content, that is, a content model using an xs:all compositor
      Returns:
      true if the type has an "all" content model
    • getSimpleContentType

      SimpleType getSimpleContentType()
      Get the simple content type. This represents one aspect of the {content type} property in the schema component model.
      Returns:
      For a complex type with simple content, returns the simple type of the content. Otherwise, returns null.
    • isRestricted

      boolean isRestricted()
      Test whether this complex type is derived by restriction. This corresponds to one aspect of the {derivation method} property in the schema component model.
      Returns:
      true if this complex type is derived by restriction
    • isEmptyContent

      boolean isEmptyContent()
      Test whether the content model of this complex type is empty. This represents one aspect of the {content type} property in the schema component model.
      Returns:
      true if the content model is defined as empty
    • isEmptiable

      boolean isEmptiable() throws SchemaException
      Test whether the content model of this complex type allows empty content. This property applies only if this is a complex type with complex content.
      Returns:
      true if empty content is valid
      Throws:
      SchemaException
    • isMixedContent

      boolean isMixedContent()
      Test whether this complex type allows mixed content. This represents one aspect of the {content type} property in the schema component model. This property applies only if this is a complex type with complex content.
      Returns:
      true if mixed content is allowed
    • getElementParticleType

      SchemaType getElementParticleType(int fingerprint, boolean considerExtensions) 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
      considerExtensions -
      Returns:
      the schema type associated with the child element particle with the given name. If there is no such particle, return null.
      Throws:
      SchemaException
      ValidationException
    • getElementParticleCardinality

      int getElementParticleCardinality(int fingerprint, boolean searchExtensionTypes) 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 StaticProperty.EMPTY.
      Parameters:
      fingerprint - Identifies the name of the child element within this content model
      searchExtensionTypes -
      Returns:
      the cardinality associated with the child element particle with the given name. If there is no such particle, return StaticProperty.EMPTY.
      Throws:
      SchemaException
      ValidationException
    • getAttributeUseType

      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
      Returns:
      the schema type associated with the attribute use identified by the fingerprint. If there is no such attribute use, return null.
      Throws:
      SchemaException
      ValidationException
    • allowsAttributes

      boolean allowsAttributes()
      Return true if this type (or any known type derived from it by extension) allows the element to have one or more attributes.
      Returns:
      true if attributes are allowed
    • gatherAllPermittedChildren

      void gatherAllPermittedChildren(IntHashSet children) throws SchemaException
      Get a list of all the names of elements that can appear as children of an element having this complex type, as integer fingerprints. If the list is unbounded (because of wildcards or the use of xs:anyType), return null.
      Parameters:
      children - an integer set, initially empty, which on return will hold the fingerprints of all permitted child elements; if the result contains the value -1, this indicates that it is not possible to enumerate all the children, typically because of wildcards. In this case the other contents of the set should be ignored.
      Throws:
      SchemaException
    • gatherAllPermittedDescendants

      void gatherAllPermittedDescendants(IntHashSet descendants) throws SchemaException
      Get a list of all the names of elements that can appear as descendants of an element having this complex type, as integer fingerprints. If the list is unbounded (because of wildcards or the use of xs:anyType), include a -1 in the result.
      Parameters:
      descendants - an integer set, initially empty, which on return will hold the fingerprints of all permitted descendant elements; if the result contains the value -1, this indicates that it is not possible to enumerate all the descendants, typically because of wildcards. In this case the other contents of the set should be ignored.
      Throws:
      SchemaException
