org.apache.fop.fo.expr.RelativeNumericProperty
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. |

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 |
double |
getTableUnits()
Return the number of table units which are included in this length specification. |
int |
getValue()
Returns the length in 1/1000ths of a point (millipoints) |
int |
getValue(PercentBaseContext context)
Returns the length in 1/1000ths of a point (millipoints) |

hashCode()
|
boolean |
isAbsolute()
Return false since an expression is only created when there is relative numerics involved. |
java.lang.String |
