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

      • allowsAttributes

        public 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.
        Specified by:
        allowsAttributes in interface ComplexType
        Returns:
        true if attributes are allowed

      • gatherAllPermittedChildren

        public void gatherAllPermittedChildren​(IntHashSet children,
                                       boolean ignoreWildcards)
        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.
        Specified by:
        gatherAllPermittedChildren in interface ComplexType
        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
        ignoreWildcards - true if wildcards are to be ignored, rather than a wildcard causing the result to be considered

      • gatherAllPermittedDescendants

        public void gatherAllPermittedDescendants​(IntHashSet descendants)
        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), return null.
        Specified by:
        gatherAllPermittedDescendants in interface ComplexType
        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.

      • getDescendantElementType

        public SchemaType getDescendantElementType​(int fingerprint)
        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.
        Specified by:
        getDescendantElementType in interface ComplexType
        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

        public int getDescendantElementCardinality​(int elementFingerprint)
        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.
        Specified by:
        getDescendantElementCardinality in interface ComplexType
        Parameters:
        elementFingerprint - the name of the required descendant element
        Returns:
        the cardinality of the descendant element within this complex type

      • containsElementWildcard

        public boolean containsElementWildcard()
        Ask whether this type (or any known type derived from it by extension) allows the element to have children that match a wildcard
        Specified by:
        containsElementWildcard in interface ComplexType
        Returns:
        true if the content model of this type, or its extensions, contains an element wildcard

      • hasAssertions

        public boolean hasAssertions()
        Ask whether there are any assertions defined on this complex type
        Specified by:
        hasAssertions in interface ComplexType
        Returns:
        true if there are any assertions

      • getComponentAsFunction

        public Function getComponentAsFunction()
        Description copied from interface: SchemaComponent
        Get the schema component in the form of a function item. This allows schema information to be made visible to XSLT or XQuery code. The function makes available the contents of the schema component as defined in the XSD specification. The function takes a string as argument representing a property name, and returns the corresponding property of the schema component. There is also a property "class" which returns the kind of schema component, for example "Attribute Declaration".
        Specified by:
        getComponentAsFunction in interface SchemaComponent
        Returns:
        the schema component represented as a function from property names to property values.
