Interface ComplexType

All Superinterfaces:
SchemaComponent, SchemaType, Serializable
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

gatherAllPermittedChildren

public 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.

gatherAllPermittedDescendants

public 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.

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

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 StaticProperty.EMPTY.
Parameters:
fingerprint - Identifies the name of the child element within this content model
Returns:
the cardinality associated with the child element particle with the given name. If there is no such particle, return StaticProperty.EMPTY.

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
Returns:
the schema type associated with the child element particle with the given name. If there is no such particle, return null.

getSimpleContentType

public 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.

isAbstract

public 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.

isAllContent

public 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

isComplexContent

public 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

isEmptiable

public 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

isEmptyContent

public 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

isMixedContent

public 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

isRestricted

public 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

isSimpleContent

public 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
