- Method Detail
  - getInstance
```
public static AnyItemType getInstance()
```

    Specified by:
    
    getGenre in interface ItemType
    
    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
    
    Returns:
    
    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 java.lang.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 -
    
    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 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.
