net.sf.saxon.type.AnyItemType
All Implemented Interfaces:

  • Method Details

    • getInstance

      Returns:
      the Genre to which this type belongs, specifically Genre.ANY

    • getUType

      public UType getUType()
      Get the corresponding UType. A UType is a union of primitive item types.
      Specified by:
      getUType in interface ItemType

      the smallest UType that subsumes this item type

    • isAtomicType

      public boolean isAtomicType()
      Determine whether this item type is an atomic type
      Specified by:
      isAtomicType in interface ItemType
      Returns:
      true if this is ANY_ATOMIC_TYPE or a subtype thereof

    • getBasicAlphaCode

      public String getBasicAlphaCode()
      Get an alphabetic code representing the type, or at any rate, the nearest built-in type from which this type is derived. The codes are designed so that for any two built-in types A and B, alphaCode(A) is a prefix of alphaCode(B) if and only if A is a supertype of B.
      Specified by:
      getBasicAlphaCode in interface ItemType
      Returns:
      the alphacode for the nearest containing built-in type

    • isPlainType

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

    • matches

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

    • 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 xs: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
      Returns:
      the corresponding primitive type

    • 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 BuiltInAtomicType.ANY_ATOMIC. 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
      Returns:
      the integer fingerprint of the corresponding primitive type

    • 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
      Returns:
      the best available item type of the atomic values that will be produced when an item of this type is atomized, or null if it is known that atomization will throw an error.

    • isAtomizable

      public boolean isAtomizable(TypeHierarchy th)
      Ask whether values of this type are atomizable
      Specified by:
      isAtomizable in interface ItemType
      Parameters:
      th - The type hierarchy cache
      Returns:
      true unless it is known that these items will be elements with element-only content, in which case return false

    • getDefaultPriority

      public double getDefaultPriority()
      Description copied from interface: ItemType
      Get the default priority when this ItemType is used as an XSLT pattern
      Specified by:
      getDefaultPriority in interface ItemType
      Returns:
      the default priority
