Constructor Detail

NotationValue

public NotationValue(String prefix,
                     String uri,
                     String localName,
                     NameChecker checker)
              throws XPathException
Constructor

Parameters:
prefix - The prefix part of the QName (not used in comparisons). Use null or "" to represent the default prefix.
uri - The namespace part of the QName. Use null or "" to represent the null namespace.
localName - The local part of the QName
checker - Used for checking names against XML 1.0 or XML 1.1 syntax rules
Throws:
XPathException

NotationValue

public NotationValue(String prefix,
                     String uri,
                     String localName)
Constructor for a value that is known to be valid

Parameters:
prefix - The prefix part of the QName (not used in comparisons). Use null or "" to represent the default prefix.
uri - The namespace part of the QName. Use null or "" to represent the null namespace.
localName - The local part of the QName

NotationValue

public NotationValue(String prefix,
                     String uri,
                     String localName,
                     AtomicType typeLabel)
Constructor for a value that is known to be valid

Parameters:
prefix - The prefix part of the QName (not used in comparisons). Use null or "" to represent the default prefix.
uri - The namespace part of the QName. Use null or "" to represent the null namespace.
localName - The local part of the QName
typeLabel - A type derived from xs:NOTATION to be used for the new value
Method Detail

copyAsSubType

public AtomicValue copyAsSubType(AtomicType typeLabel)
Create a copy of this atomic value, with a different type label

Specified by:
copyAsSubType in class AtomicValue
Parameters:
typeLabel - the type label of the new copy. The caller is responsible for checking that the value actually conforms to this type.
Returns:
the copied value

getPrimitiveType

public BuiltInAtomicType getPrimitiveType()
Determine the primitive type of the value. This delivers the same answer as getItemType().getPrimitiveItemType(). The primitive types are the 19 primitive types of XML Schema, plus xs:integer, xs:dayTimeDuration and xs:yearMonthDuration, and xs:untypedAtomic. For external objects, the result is AnyAtomicType.

Specified by:
getPrimitiveType in class AtomicValue
Returns:
the primitive type

convertPrimitive

public ConversionResult convertPrimitive(BuiltInAtomicType requiredType,
                                         boolean validate,
                                         XPathContext context)
Convert to target data type

Parameters:
requiredType - an integer identifying the required atomic type
context - The XPath dynamic context
validate - true if validation is required. If set to false, the caller guarantees that the value is valid for the target data type, and that further validation is therefore not required. Note that a validation failure may be reported even if validation was not requested.
Returns:
an AtomicValue, a value of the required type; or an ErrorValue

equals

public boolean equals(Object other)
Determine if two Notation values are equal. This comparison ignores the prefix part of the value.

Specified by:
equals in class AtomicValue
Parameters:
other - the other value
Returns:
true if the other operand is an atomic value and the two values are equal as defined by the XPath eq operator
Throws:
ClassCastException - if they are not comparable
IllegalStateException - if the two QNames are in different name pools

getSchemaComparable

public Comparable getSchemaComparable()
Description copied from class: AtomicValue
Get a Comparable value that implements the XML Schema ordering comparison semantics for this value. An implementation must be provided for all atomic types.

In the case of data types that are partially ordered, the returned Comparable extends the standard semantics of the compareTo() method by returning the value Value.INDETERMINATE_ORDERING when there is no defined order relationship between two given values. This value is also returned when two values of different types are compared.

Specified by:
getSchemaComparable in class AtomicValue
Returns:
a Comparable that follows XML Schema comparison rules

toString

public String toString()
The toString() method returns the name in the form QName("uri", "local")

Overrides:
toString in class QualifiedNameValue
Returns:
the name in Clark notation: {uri}local
