Class NumericOp

java.lang.Object
org.apache.fop.fo.expr.NumericOp
public final class NumericOp extends Object
This class contains static methods to evaluate operations on Numeric operands. If the operands are absolute numerics the result is computed rigth away and a new absolute numeric is return. If one of the operands are relative a n operation node is created with the operation and the operands. The evaluation of the operation can then occur when getNumericValue() is called.
