Interface ComplexType
- All Superinterfaces:
SchemaComponent
,SchemaType
- All Known Implementing Classes:
AnyType
,Untyped
,UserComplexType
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.

-
getElementParticleType
SchemaType getElementParticleType(int elementName, boolean considerExtensions) throws MissingComponentException Find an element particle within this complex type definition having a given element name (identified by elementName), and return the schema type associated with that element particle. If there is no such particle, return null. If the elementName 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:
elementName
- Identifies the name of the child element within this content modelconsiderExtensions
- True if types derived from this type by extension are to be included in the search- Returns:
- the schema type associated with the child element particle with the given name. If there is no such particle, return null.

MissingComponentException
- if the schema is incomplete
-
getElementParticleCardinality
int getElementParticleCardinality(int elementName, boolean considerExtensions) throws MissingComponentException Find an element particle within this complex type definition having a given element name (identified by elementName), 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 ofStaticProperty.EXACTLY_ONE

gatherAllPermittedChildren
void gatherAllPermittedChildren(IntHashSet children, boolean ignoreWildcards) 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
- a set, initially empty, which on return will hold the names 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 ignoredignoreWildcards
- true if wildcards should be ignored- Throws:
SchemaException
-
gatherAllPermittedDescendants
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
- a set, initially empty, which on return will hold the names 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
-
getDescendantElementType
Assuming an element is a permitted descendant in the content model of this type, determine the type of the element when it appears as a descendant. If it appears with more than one type, return xs:anyType.- Parameters:
fingerprint
- the name of the required descendant element- Returns:
- the type of the descendant element; null if the element cannot appear as a descendant; anyType if it can appear with several different types

getDescendantElementCardinality
Assuming an element is a permitted descendant in the content model of this type, determine the cardinality of the element when it appears as a descendant.- Parameters:

- true if the content model of this type, or its extensions, contains an element wildcard
