Constructor Detail

NumericValue

protected NumericValue(N val)
                throws IllegalArgumentException,
                       NullPointerException

Constructor for NumericValue.

Parameters:

val - a N object.

Throws:

IllegalArgumentException - if rawVal == null

NullPointerException - if datatypeId == null

Method Detail

abs

public abstract NAV abs()

Returns the absolute value of this. Used by the XACML "abs" functions.

Returns:

the absolute value

add

public abstract NAV add(Deque<? extends NAV> others)
                 throws ArithmeticException

Adds numbers to this. Used by the XACML numeric *-add functions.

Parameters:

others - values to add to this value

Returns:

sum of this and the others.

Throws:

ArithmeticException - if the result overflows the value space of N

subtract

public abstract NAV subtract(NAV subtractedVal)
                      throws ArithmeticException

Subtract a number from this. Used by XACML numeric *-subtract functions.

Parameters:

subtractedVal - value to be subtracted from this

Returns:

this - subtractedVal

Throws:

ArithmeticException - if the result overflows the value space of N

multiply

public abstract NAV multiply(Deque<? extends NAV> others)
                      throws ArithmeticException

Multiply this by other numbers. Used by the XACML "multiply" functions.

Parameters:

others - other values to multiply by

Returns:

product of this by the others

Throws:

ArithmeticException - if the result overflows the value space of N

divide

public abstract NAV divide(NAV divisor)
                    throws ArithmeticException

Divide this by some other number. Used by XACML *-divide functions.

Parameters:

divisor - number by which this is divided

Returns:

the result quotient

Throws:

ArithmeticException - if divisor is zero
