Constructor Detail

### ElementWildcard

    public ElementWildcard()

Method Detail

### getMinOccurs

    public int getMinOccurs()

  Get the minOccurs attribute

  Specified by:
    `getMinOccurs` in interface `Particle`
  Returns:
    the minOccurs attribute (default 1)

### setMinOccurs

    public void setMinOccurs(int minOccurs)

  Set the minOccurs attribute.

  Specified by:
    `setMinOccurs` in interface `Particle`
  Parameters:
    `minOccurs` - the value of the minOccurs attribute

### getMaxOccurs

    public int getMaxOccurs()

  Get the maxOccurs attribute

  Specified by:
    `getMaxOccurs` in interface `Particle`
  Returns:
    the value of the attribute (unbounded = -1)

### setMaxOccurs

    public void setMaxOccurs(int maxOccurs)

  Set the maxOccurs attribute

  Parameters:
    `maxOccurs` - the value of the attribute (unbounded = -1)

### isEmptiable

    public boolean isEmptiable()

  Determine if this particle can be empty

  Specified by:
    `isEmptiable` in interface `Particle`

### isPointless

    public boolean isPointless(Particle container)

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

  Specified by:
    `isPointless` in interface `Particle`

### getTerm

    public Term getTerm()

  Get the term represented by this particle

  Specified by:
    `getTerm` in interface `Particle`

### fixup

    public boolean fixup(SchemaCompiler compiler)
                  throws SchemaException

  Check references from this component to other components

  Specified by:
    `fixup` in interface `UserSchemaComponent`
  Parameters:
    `compiler` -
  Returns:
    true if all is well, false if errors found
  Throws:
    `SchemaException`

### compile

    public void compile(SchemaCompiler compiler)
                 throws SchemaException

  Description copied from interface: `Particle`
  Compile a particle

  Specified by:
    `compile` in interface `Particle`
  Throws:
    `SchemaException`

### getElementParticleType

    public SchemaType getElementParticleType(int fingerprint)

  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.

  Specified by:
    `getElementParticleType` in interface `Particle`
  Parameters:
    `fingerprint` - Identifies the name of the child element within this content model

### 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 zero.

  Specified by:
    `getElementParticleCardinality` in interface `Particle`
  Parameters:
    `fingerprint` - Identifies the name of the child element within this content model
  Throws:
    `SchemaException`
    `ValidationException`

### gatherAllPermittedElements

    public void gatherAllPermittedElements(IntHashSet result)
                                    throws SchemaException,
                                           ValidationException

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

  Specified by:
    `gatherAllPermittedElements` in interface `Particle`
  Parameters:
    `result` - an initially-empty integer set in which the results are accumulated
  Throws:
    `SchemaException`
    `ValidationException`

### serialize

    public void serialize(SchemaSerializer serializer)
                   throws IOException

  Serialize the schema component

  Specified by:
    `serialize` in interface `SerializableSchemaComponent`
  Throws:
    `IOException`

### getComponentTypeCode

    public int getComponentTypeCode()

  Get a unique number identifying the type of component

  Specified by:
    `getComponentTypeCode` in interface `SerializableSchemaComponent`
