net.sf.saxon.value.IntegerValue
An integer value: note this is a subtype of decimal in XML Schema, not a primitive type. This class also supports the built-in subtypes of xs:integer. Actually supports a value in the range permitted by a Java "long"

public IntegerValue(long value)
value - the value of the IntegerValue
public IntegerValue(long val,
AtomicType type)
throws DynamicError
val - The supplied value, as an integertype - the required item type, a subtype of xs:integer
DynamicError - if the supplied value is out of range for the
target type| Method Detail |
public ValidationException convertToSubtype(AtomicType subtype,
boolean validate)
subtype - the target subtypevalidate - true if validation is required; false if the caller already knows that the value is valid
public void setSubType(AtomicType type)
public boolean checkRange(AtomicType type)
type - the subtype of integer required
public static AtomicValue stringToInteger(java.lang.CharSequence s)
s - CharSequence representing the string to be converted
public int hashCode()
hashCode in class NumericValueNumericValue.hashCode()public long longValue()
longValue in class NumericValuepublic boolean effectiveBooleanValue(XPathContext context)
effectiveBooleanValue in interface ExpressioneffectiveBooleanValue in class AtomicValuecontext - The dynamic evaluation context; ignored in this
implementation of the method
public int compareTo(java.lang.Object other)
compareTo in interface java.lang.ComparablecompareTo in class NumericValueother - the numeric value to be compared to this value
public int compareTo(long other)
compareTo in class NumericValueother - the value to be compared with
public AtomicValue convertPrimitive(BuiltInAtomicType requiredType,
boolean validate,
XPathContext context)
convertPrimitive in class AtomicValuerequiredType - an integer identifying the required atomic typecontext - 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.
public java.lang.String getStringValue()
getStringValue in interface ItemgetStringValue in class AtomicValuepublic NumericValue negate()
negate in class NumericValuepublic NumericValue floor()
floor in class NumericValuepublic NumericValue ceiling()
ceiling in class NumericValuepublic NumericValue round()
round in class NumericValuepublic NumericValue roundHalfToEven(int scale)
roundHalfToEven in class NumericValuescale - number of digits required after the decimal point; the
value -2 (for example) means round to a multiple of 100
public double signum()
signum in class NumericValuepublic boolean isWholeNumber()
isWholeNumber in class NumericValue
public NumericValue arithmetic(int operator,
NumericValue other,
XPathContext context)
throws XPathException
arithmetic in class NumericValueoperator - the operator to be applied, identified by a constant in
the Tokenizer classother - the other operand of the arithmetic expression
XPathException - if an arithmetic failure occurs, e.g. divide
by zeroTokenizerpublic ItemType getItemType(TypeHierarchy th)
getItemType in interface ExpressiongetItemType in class Valueth -
public java.lang.Object convertToJava(java.lang.Class target,
XPathContext context)
throws XPathException
convertToJava in class Valuetarget - The Java class to which conversion is required
XPathException - if conversion is not possible, or fails
