- Method Detail
  - 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 xs: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 - the type hierarchy cache
    
    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.

  - 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

  - toString
```
public java.lang.String toString()
```
    Overrides:
    
    toString in class java.lang.Object
  - toString
```
public java.lang.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.
    
    Overrides:
    
    hashCode in class java.lang.Object
