Method Summary

Modifier and Type	Method	Description
NodeTest	asXNodeTest(Configuration config)	Get an XNodeTest that will match any XNode that this NodeTest matches: that is, eliminate the possibility of matching a JNode.
String	getBasicAlphaCode()	Get an alphabetic code representing the type, or at any rate, the nearest built-in type from which this type is derived.
CoercionPlan	getCoercionPlan(int version)	Get the coercion plan for use when this type is the required type for (say) coercion of arguments in a function call
double	getDefaultPriority()	Get the default priority when this ItemType is used as an XSLT pattern
Genre	getGenre()	Determine the Genre (top-level classification) of this type
ItemType	getPrimitiveItemType()	Get the primitive item type corresponding to this item type.
int	getPrimitiveType()	Get the primitive type corresponding to this item type.
UType	getUType()	Get the corresponding UType.

Constructor Details

JNodeType

public JNodeType()

Method Details

getValueType

public SequenceType getValueType()

getGenre

public Genre getGenre()

Determine the Genre (top-level classification) of this type

Specified by:

getGenre in interface ItemType

Overrides:

getGenre in class GNodeType

Returns:

the Genre to which this type belongs, for example node or atomic value

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 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 interface ItemType

Overrides:

getPrimitiveItemType in class GNodeType

Returns:

the corresponding primitive type

getPrimitiveType

public int getPrimitiveType()

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

Overrides:

getPrimitiveType in class GNodeType

Returns:

the integer fingerprint of the corresponding primitive type

getUType

public UType getUType()

Get the corresponding UType. A UType is a union of primitive item types.

Specified by:

getUType in interface ItemType

Specified by:

getUType in interface NodeTest

Overrides:

getUType in class GNodeType

Returns:

the smallest UType that subsumes this item type

getDefaultPriority

public double getDefaultPriority()

Get the default priority when this ItemType is used as an XSLT pattern

Returns:

the default priority

getCoercionPlan

public CoercionPlan getCoercionPlan(int version)

Get the coercion plan for use when this type is the required type for (say) coercion of arguments in a function call

Specified by:

getCoercionPlan in interface ItemType

Overrides:

getCoercionPlan in class GNodeType

Parameters:

version - the XPath language version (40 or 31)

getBasicAlphaCode

public 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.

Returns:

the alphacode for the nearest containing built-in type. For example: for xs:string return "AS", for xs:boolean "AB", for node() "N", for element() "NE", for map(*) "FM", for array(*) "FA".

asXNodeTest

public NodeTest asXNodeTest(Configuration config)

Description copied from interface: NodeTest

Get an XNodeTest that will match any XNode that this NodeTest matches: that is, eliminate the possibility of matching a JNode.
