Class BuiltInListType

java.lang.Object
net.sf.saxon.type.BuiltInListType
All Implemented Interfaces:
CastingTarget, HyperType, ListType, SchemaComponent, SchemaType, SimpleType
public class BuiltInListType extends Object implements ListType

This class is used to implement the built-in list types NMTOKENS, ENTITIES, IDREFS. It is also used to represent the anonymous type of the xsi:schemaLocation attribute (a list of xs:anyURI values).

  • Field Details

  • Constructor Details

    • BuiltInListType

      public BuiltInListType(int fingerprint)
      Create a new ListType.
      Parameters:
      fingerprint - identifies the name of the type

  • Method Details

    • 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

    • getSystemId

      public String getSystemId()
      Get the URI of the schema document containing the definition of this type
      Specified by:
      getSystemId in interface SchemaType
      Returns:
      null for 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

    • getWhitespaceAction

      public int getWhitespaceAction()
      Determine how values of this simple type are whitespace-normalized.
      Specified by:
      getWhitespaceAction in interface SimpleType
      Returns:
      one of Whitespace.PRESERVE, Whitespace.COLLAPSE, Whitespace.REPLACE.

      public SchemaValidationStatus getValidationStatus()
      Get the validation status - always valid
      Specified by:
      getValidationStatus in interface SchemaComponent
      Returns:
      one of the values SchemaValidationStatus.UNVALIDATED, SchemaValidationStatus.VALIDATING, SchemaValidationStatus.VALIDATED, SchemaValidationStatus.INVALID, SchemaValidationStatus.INCOMPLETE

    • getBaseType

      public SchemaType getBaseType()
      Returns the base type that this type inherits from. If this type is a Simpletype that is a built in primitive type then null is returned.

      true if this type is an IDREF type

    • isListType
