public class RelativeNumericProperty
This class represent a node in a property expression tree. It is created when an operation involve relative expression and is used to delay evaluation of the operation until the time where getNumericValue() or getValue() is called.

int |
getDimension()
Return the dimension of the expression |
Length |
getLength()
Cast this numeric as a Length. |
Numeric |
getNumeric()
This method expects to be overridden by subclasses |
double |
getNumericValue()
Return the resolved (calculated) value of the expression. |
double |
getNumericValue(PercentBaseContext context)
Return the value of this Numeric |
int |
getValue()
Returns the value of this numeric as an int. |
int |
getValue(PercentBaseContext context)
Returns the value of this numeric as an int. |
boolean |
isAbsolute()
Return false since an expression is only created when there is relative numerics involved. |
