Field Detail
ONE
final public static BigDecimal ONE(Code)



ONE_MILLION
final public static BigDecimal ONE_MILLION(Code)



TEN
final public static BigInteger TEN(Code)




Constructor Detail
DecimalValue
public DecimalValue(BigDecimal value)(Code)
Constructor supplying a BigDecimal
Parameters:
  value - the value of the DecimalValue



DecimalValue
public DecimalValue(double in) throws ValidationException(Code)
Constructor supplying a double
Parameters:
  in - the value of the DecimalValue



DecimalValue
public DecimalValue(long in)(Code)
Constructor supplying a long integer
Parameters:
  in - the value of the DecimalValue




Method Detail
arithmetic
public NumericValue arithmetic(int operator, NumericValue other, XPathContext context) throws XPathException(Code)
Evaluate a binary arithmetic operator.



ceiling
public NumericValue ceiling()(Code)
Implement the XPath ceiling() function



compareTo
public int compareTo(Object other)(Code)
Compare the value to another numeric value



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



convertToJava
public Object convertToJava(Class target, XPathContext context) throws XPathException(Code)
Convert to Java object (for passing to external functions)



decimalToString
public static String decimalToString(BigDecimal value)(Code)



effectiveBooleanValue
public boolean effectiveBooleanValue(XPathContext context)(Code)



floor
public NumericValue floor()(Code)
Implement the XPath floor() function



getItemType
public ItemType getItemType(TypeHierarchy th)(Code)
Determine the data type of the expression Type.DECIMAL
Parameters:
  th -



getStringValue
public String getStringValue()(Code)
Get the value as a String a String representation of the value



getValue
public BigDecimal getValue()(Code)
Get the value



hashCode
public int hashCode()(Code)
Get the hashCode. This must conform to the rules for other NumericValue hashcodes
See Also:   NumericValue.hashCode



isWholeNumber
public boolean isWholeNumber()(Code)
Determine whether the value is a whole number, that is, whether it compares equal to some integer



makeDecimalValue
public static AtomicValue makeDecimalValue(CharSequence in, boolean validate)(Code)
Factory method to construct a DecimalValue from a string
Parameters:
  in - the value of the DecimalValue
Parameters:
  validate - true if validation is required; false if the caller knows that the value is valid the required DecimalValue if the input is valid, or an ErrorValue encapsulating the errormessage if not.



negate
public NumericValue negate()(Code)
Negate the value



round
public NumericValue round()(Code)
Implement the XPath round() function



roundToHalfEven
public NumericValue roundToHalfEven(int scale)(Code)
Implement the XPath round-to-half-even() function



schemaEquals
public boolean schemaEquals(Value obj)(Code)
Compare two values for equality. This supports identity constraints in XML Schema, which allow list-valued elements and attributes to participate in key and uniqueness constraints. This method returns false if any error occurs during the comparison, or if any of the items in either sequence is a node rather than an atomic value. The default implementation of schemaEquals() is the same as equals(), but subclasses can override this.



signum
public double signum()(Code)
Determine whether the value is negative, zero, or positive -1 if negative, 0 if zero, +1 if positive, NaN if NaN
