Constructor Detail

UnionType

public UnionType(Schema schema)
          throws SchemaException

Creates a new Union type.

Parameters:

schema - the Schema for this Union (Cannot be null)

setMemberTypes

public void setMemberTypes(java.util.List members)

Set the member types of this union type

getMemberTypes

public java.util.List getMemberTypes()

Get the list of member types, as a List containing SimpleType objects

iterateMemberTypes

public java.util.Iterator iterateMemberTypes()

Returns an Iterator over all the SimpleTypes that are members of a union type. Note that this is not transitive: if the union has another union as a membertype, the iteration will return this union rather than its members.

Overrides:

iterateMemberTypes in class SimpleType

Returns:

For union types, return an Iterator over all member SimpleTypes. For non-union types, return null.

isListType

public boolean isListType()

Determine whether any member of this union is a list type. This is recursive; if a member of the union is a union type containing a list type as one of its members, the result is true.

Overrides:

isListType in class SimpleType

Returns:

true if this is a list type

isUnionType

public boolean isUnionType()

Return true if this type is a union type (that is, if its variety is union)

Overrides:

isUnionType in class SimpleType

Returns:

true for a union type

validate

public boolean validate(SchemaMarker schema)
                 throws javax.xml.transform.TransformerException

Validate this Union, replacing all unresolved forwards references at the same time

Overrides:

validate in class SimpleType

Parameters:

schema - a Schema used for error reporting

Throws:

javax.xml.transform.TransformerException

validateContent

public void validateContent(java.lang.CharSequence value,
                            NamespaceResolver nsResolver)
                     throws ValidationException

Description copied from class: SimpleType

Check whether a given input string is valid according to this SimpleType

Specified by:

validateContent in class SimpleType

Parameters:

value - the input string to be checked

nsResolver - a namespace resolver used to resolve namespace prefixes if the type is namespace sensitive. The value supplied may be null; in this case any namespace-sensitive content will throw an UnsupportedOperationException.

Throws:

ValidationException - if the content is invalid

getTypedValue

public SequenceIterator getTypedValue(java.lang.CharSequence value,
                                      NodeInfo node)
                               throws ValidationException

Description copied from class: SimpleType

Get the typed value corresponding to a given string value, assuming it is valid against this type

Specified by:

getTypedValue in class SimpleType

Parameters:

value - the string value

node - the containing node: used only to resolve namespace prefixes in QName-valued content

Returns:

an iterator over the atomic sequence comprising the typed value. The objects returned by this SequenceIterator will all be of type AtomicValue

ValidationException
