  • Method Details

    • getName

      public String getName()
      Get the local name of this type
      Specified by:
      getName in interface SchemaType
      Returns:
      the local name of this type definition, if it has one. Return null in the case of an anonymous type.
    • getTargetNamespace

      public String getTargetNamespace()
      Get the target namespace of this type
      Specified by:
      getTargetNamespace in interface SchemaType
      Returns:
      the target namespace of this type definition, if it has one. Return null in the case of an anonymous type, and in the case of a global type defined in a no-namespace schema.
    • isExternalType

      public boolean isExternalType()
      Return true if this is an external object type, that is, a Saxon-defined type for external Java or .NET objects
      Specified by:
      isExternalType in interface SimpleType
      Returns:
      true if this is an external type
    • isBuiltInType

      public boolean isBuiltInType()
      Determine whether this is a built-in type or a user-defined type
      Specified by:
      isBuiltInType in interface SimpleType
      Returns:
      true if this is a built-in type
    • getRedefinitionLevel

      public int getRedefinitionLevel()
      Get the redefinition level. This is zero for a component that has not been redefined; for a redefinition of a level-0 component, it is 1; for a redefinition of a level-N component, it is N+1. This concept is used to support the notion of "pervasive" redefinition: if a component is redefined at several levels, the top level wins, but it is an error to have two versions of the component at the same redefinition level.
      Specified by:
      getRedefinitionLevel in interface SchemaComponent
      Returns:
      the redefinition level
    • getSystemId

      Specified by:
      getSystemId in interface SchemaType
      Returns:
      null for a built-in type

      the singular object representing xs:anyType

      Get the namecode of the name of this type. This includes the prefix from the original type declaration: in the case of built-in types, there may be a conventional prefix or there may be no prefix.
      Specified by:
      getNameCode in interface SchemaType
      Returns:
      the namecode. Returns an invented namecode for an anonymous type.

    • getTypedValue

      public SequenceIterator getTypedValue(NodeInfo node)
      Get the typed value of a node that is annotated with this schema type. This shouldn't happen: nodes are never annotated as xs:error; but if it does happen, we treat it as if it were untypedAtomic.
      Specified by:
      getTypedValue in interface SchemaType
      Parameters:
      node - the node whose typed value is required
      Returns:
      an iterator returning a single untyped atomic value, equivalent to the string value of the node.
    • atomize

      public Value atomize(NodeInfo node)
      Get the typed value of a node that is annotated with this schema type. The result of this method will always be consistent with the method getTypedValue(net.sf.saxon.om.NodeInfo). However, this method is often more convenient and may be more efficient, especially in the common case where the value is expected to be a singleton.
      Specified by:
      atomize in interface SchemaType
      Parameters:
      node - the node whose typed value is required
      Returns:
      the typed value.

      Ask whether this type is an ID type. This is defined to be any simple type who typed value may contain atomic values of type xs:ID: that is, it includes types derived from ID by restriction, list, or union. Note that for a node to be treated as an ID, its typed value must be a *single* atomic value of type ID; the type of the node, however, can still allow a list.
