public interface TypeInfo
The TypeInfo
interface represent a type referenced from Element
or Attr
nodes, specified in the schemas associated with the document. The type is a pair of a namespace URI and name properties, and depends on the document's schema.
If the document's schema is an XML DTD [XML 1.0], the values are computed as follows:
Attr
node, typeNamespace
is null
and typeName
represents the [attribute type] property in the [XML Information Set] . If there is no declaration for the attribute, typeName
is null
.Element
node, the typeNamespace
and typeName
are null
.If the document's schema is an XML Schema [XML Schema Part 1] , the values are computed as follows using the post-schema-validation infoset contributions (also called PSVI contributions):
null
.
Note: At the time of writing, the XML Schema specification does not require exposing the declared type. Thus, DOM implementations might choose not to provide type information if validity is not valid.
Note: Other schema languages are outside the scope of the W3C and therefore should define how to represent their type systems using TypeInfo
.
See also the Document Object Model (DOM) Level 3 Core Specification.
Field Summary | |
---|---|
static int |
DERIVATION_EXTENSION If the document's schema is an XML Schema [XML Schema Part 1] , this constant represents the derivation by extension if complex types are involved. |
static int |
DERIVATION_LIST If the document's schema is an XML Schema [XML Schema Part 1] , this constant represents the list if simple types are involved. |
static int |
DERIVATION_RESTRICTION If the document's schema is an XML Schema [XML Schema Part 1] , this constant represents the derivation by restriction if complex types are involved, or a restriction if simple types are involved. |
static int |
DERIVATION_UNION If the document's schema is an XML Schema [XML Schema Part 1] , this constant represents the union if simple types are involved. |
Method Summary | |
---|---|
java.lang.String |
getTypeName() The name of a type declared for the associated element or attribute, or null if unknown. |
java.lang.String |
getTypeNamespace() The namespace of the type declared for the associated element or attribute or null if the element does not have declaration or if no namespace information is available. |
boolean |
isDerivedFrom(java.lang.String typeNamespaceArg, java.lang.String typeNameArg, int derivationMethod) The method checks if this TypeInfo derives from the specified ancestor type. |

derives from the specified ancestor type.typeNamespaceArg
- the namespace of the ancestor type.typeNameArg
- the name of the ancestor type.derivationMethod
- the type of derivation and conditions applied between two types, as described in the list of constants provided in this interface. Note that those constants:
TypeInfo.DERIVATION_EXTENSION
only applies to XML Schema complex types.0x00000000
represents any kind of derivation method.true
if the specified type is an ancestor according to the derivation parameter, false
otherwise. If the document's schema is a DTD or no schema is associated with the document, this method will always return false
