Method Detail

getInstance

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


matchesItem

public boolean matchesItem(Item item)
Test whether a given item conforms to this type

Specified by:
matchesItem in interface ItemType
Parameters:
item - The item to be tested
Returns:
true if the item is an instance of this type; false otherwise

getSuperType

public ItemType getSuperType()
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).

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

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: note that INTEGER is not a primitive type.

Specified by:
getPrimitiveType in interface ItemType

toString

public String toString()
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

isSameType

public boolean isSameType(ItemType other)
Description copied from interface: ItemType
Test whether this is the same type as another ItemType. Following stylesheet compilation, comparing the objects for Java identity doesn't work

Specified by:
isSameType in interface ItemType
