Method Detail

copy

public ElementWildcard copy()

setWildcard

public void setWildcard(Wildcard wildcard)

getWildcard

public Wildcard getWildcard()

isEmptiable

public boolean isEmptiable()

Determine if this particle can be empty

Specified by:

isEmptiable in class Particle

Returns:

true if the particle matches empty content

isPointless

public boolean isPointless(ModelGroup container)

Test whether the particle is pointless, as described in XML Schema Part 1 Schema Component Constraint: Particle Valid (Restriction)

Specified by:

isPointless in class Particle

Parameters:

container - the model group containing this particle; null if there is no containing model group

Returns:

true if the particle is pointless (for example, a sequence of one item)

getTerm

public Term getTerm()

Get the term represented by this particle

Specified by:

getTerm in class Particle

Returns:

the corresponding term

fixup

public boolean fixup(SchemaCompiler compiler)
              throws SchemaException

Check references from this component to other components

Specified by:

fixup in interface UserSchemaComponent

Specified by:

fixup in class Particle

Parameters:

compiler - the schema compiler

Returns:

true if all is well, false if errors found

Throws:

SchemaException

compile

public void compile(SchemaCompiler compiler)
             throws SchemaException

Description copied from class: Particle

Compile a particle

Specified by:

compile in class Particle

Parameters:

compiler - the schema compiler

Throws:

SchemaException - if a fatal error occurs

getElementParticleType

public SchemaType getElementParticleType(StructuredQName elementName)

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.

Specified by:

getElementParticleType in class Particle

Parameters:

elementName - Identifies the name of the child element within this content model

Returns:

the type of the element identified by the given name fingerprint. The consistency rule "Element Declarations Consistent" ensures that if there are multiple matching declarations, they have consistent types

getElementParticleCardinality

public int getElementParticleCardinality(StructuredQName elementName)

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.ALLOWS_ZERO.

Specified by:

getElementParticleCardinality in class Particle

Parameters:

elementName - Identifies the name of the child element within this content model

Returns:

the computed cardinality of this child element within the complex type

containsElementWildcard

public boolean containsElementWildcard()

Ask whether the particle contains an element wildcard

Specified by:

containsElementWildcard in class Particle

Returns:

true if the particle is an element wildcard, or contains one

gatherAllPermittedElements

public void gatherAllPermittedElements(java.util.HashSet<StructuredQName> result,
                                       boolean ignoreWildcards)
                                throws SchemaException

Find the set of all element particles allowed within the content model of this particle, identified by their integer fingerprints.

Specified by:

gatherAllPermittedElements in class Particle

Parameters:

result - an initially-empty integer set in which the results are accumulated

ignoreWildcards - true if wildcards are to be ignored. If false, the value XS_INVALID_NAME is added to the result set if an element wildcard is present (which it is, if we get as far as here)

Throws:

SchemaException - if an error is found in the schema

validate

public boolean validate(SchemaCompiler compiler)
                 throws SchemaException

Check the validity (consistency) of this element wildcard definition.

Specified by:

validate in interface UserSchemaComponent

Specified by:

validate in class Particle

Parameters:

compiler - the schema compiler

Returns:

true if validation succeeded, false if errors were found.

Throws:

SchemaException - if an error is found and the error listener decides that the error is fatal

serializeParticle

public void serializeParticle(SchemaModelSerializer serializer)
                       throws XPathException

Serialize the particle

Specified by:

serializeParticle in class Particle

Parameters:

serializer - the object responsible for serialization

Throws:

XPathException - if writing the serialized form to the destination fails

MissingComponentException - if the schema cannot be serialized because some components are missing.

getTermComponentAsFunction

public Function getTermComponentAsFunction()
