      • 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
        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 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.
