isAtomicType
public boolean isAtomicType()Description copied from interface:ItemType
Determine whether this item type is an atomic type- Specified by:
isAtomicType
in interfaceItemType
- Returns:
- true if this is ANY_ATOMIC_TYPE or a subtype thereof
-
matches
Description copied from interface:ItemType
Test whether a given item conforms to this type -
isPlainType
public boolean isPlainType()Description copied from interface:ItemType
Determine whether this item type is a plain type (that is, whether it can ONLY match atomic values)- Specified by:
isPlainType
in interfaceItemType
- Returns:
- true if this is ANY_ATOMIC_TYPE or a subtype thereof, or a "plain" union type (that is, unions of atomic types that impose no further restrictions). Return false if this is a union type whose member types are not all known.
-
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 interfaceItemType
- Returns:
- the integer fingerprint of the corresponding primitive type
-
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 interfaceItemType
- Returns:
- the alphacode for the nearest containing built-in type
-
getPrimitiveItemType
Description copied from interface:ItemType
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 and union types 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, xs:dayTimeDuration, and xs:yearMonthDuration are considered to be primitive types.- Specified by:
getPrimitiveItemType
in interfaceItemType
- Returns:
- the corresponding primitive type
-
getUType
Description copied from interface:ItemType
Get the correspondingUType
. A UType is a union of primitive item types. -
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 interfaceItemType
- 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
Description copied from interface:ItemType
Ask whether values of this type are atomizable- Specified by:
isAtomizable
in interfaceItemType
- Parameters:
th
- the type hierarchy cache- Returns:
- true if some or all instances of this type can be successfully atomized; false if no instances of this type can be atomized
-
getGenre
Description copied from interface:ItemType
Determine the Genre (top-level classification) of this type -
getDefaultPriority
public double getDefaultPriority()Get the default priority when this ItemType is used as an XSLT pattern- Specified by:
getDefaultPriority
in interfaceItemType
- Returns:
- the default priority
-
