  • Method Details

    • getInstance

      public static AnyItemType getInstance()
      Factory method to get the singleton instance

    • isAtomicType

      public boolean isAtomicType()
      Determine whether this item type is atomic (that is, whether it can ONLY match atomic values)
      Specified by:
      isAtomicType in interface ItemType
      Returns:
      false: this type can match nodes or atomic values

    • matchesItem

      public boolean matchesItem(Item item, boolean allowURIPromotion, Configuration config)
      Test whether a given item conforms to this type
      Specified by:
      matchesItem in interface ItemType
      Parameters:
      item - The item to be tested
      allowURIPromotion -
      config -
      Returns:
      true if the item is an instance of this type; false otherwise

    • getSuperType

      public ItemType getSuperType(TypeHierarchy th)
      Description copied from interface: ItemType
      Get the type from which this item type is derived by restriction. This is the supertype in the XPath type heirarchy, as distinct from the Schema base type: this means that the supertype of xs:boolean is xdt:anyAtomicType, whose supertype is item() (rather than xs:anySimpleType).

      In fact the concept of "supertype" is not really well-defined, because the types form a lattice rather than a hierarchy. The only real requirement on this function is that it returns a type that strictly subsumes this type, ideally as narrowly as possible.

      Specified by:
      getSuperType in interface ItemType
      Parameters:
      th -
      Returns:
      the supertype, or null if this type is item()

    • getPrimitiveItemType

      public ItemType getPrimitiveItemType()
      Get the primitive item type corresponding to this item type. For item(), this is Type.ITEM. For node(), it is Type.NODE. For specific node kinds, it is the value representing the node kind, for example Type.ELEMENT. For anyAtomicValue it is Type.ATOMIC_VALUE. For numeric it is Type.NUMBER. For other atomic types it is the primitive type as defined in XML Schema, except that INTEGER is considered to be a primitive type.
      Specified by:
      getPrimitiveItemType in interface ItemType

    • getPrimitiveType

      public int getPrimitiveType()
      Description copied from interface: ItemType
      Get the primitive type corresponding to this item type. For item(), this is Type.ITEM. For node(), it is Type.NODE. For specific node kinds, it is the value representing the node kind, for example Type.ELEMENT. For anyAtomicValue it is Type.ATOMIC_VALUE. For numeric it is Type.NUMBER. For other atomic types it is the primitive type as defined in XML Schema, except that INTEGER is considered to be a primitive type.
      Specified by:
      getPrimitiveType in interface ItemType

    • getAtomizedItemType

      public AtomicType getAtomizedItemType()
      Description copied from interface: ItemType
      Get the item type of the atomic values that will be produced when an item of this type is atomized
      Specified by:
      getAtomizedItemType in interface ItemType

      public String toString()
      Overrides:

    • toString

      public String toString(NamePool pool)
      Description copied from interface: ItemType
      Produce a representation of this type name for use in error messages. Where this is a QName, it will use conventional prefixes
      Specified by:
      toString in interface ItemType

    • hashCode

      public int hashCode()
      Returns a hash code value for the object.
