              org.shapelogic.logic.ParametricRuleTask

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.lang.Iterable, javax.swing.tree.MutableTreeNode, javax.swing.tree.TreeNode, org.apache.commons.jexl.JexlContext, Calc, LazyCalc, Task

public class ParametricRuleTask
extends SimpleTask

More general task that can create all the other tasks, by taking 2 parameters.

1: A variable that the expression should work on
2: An expression that can contain the #, which will be replaced with the variable

The constructor takes a BinaryPredicate as an argument.

Constructor Detail

ParametricRuleTask

public ParametricRuleTask(BaseTask parent,
                          boolean createLocalContext,
                          java.lang.String variable,
                          java.lang.String expression,
                          java.lang.Object expectedValue,
                          java.lang.String binaryPredicateName)

Method Detail

match

public boolean match()

Description copied from class: SimpleTask

Can be overridden

Specified by:

match in interface Task

Overrides:

match in class SimpleTask

transformExpression

public static java.lang.String transformExpression(java.lang.String variable,
                                                   java.lang.String expression)

Transform an expression and a variable to an expression where the variable has been substituted for #. E.g. "polygon", "#.getHorizontalLines().size()" -> "polygon.getHorizontalLines().size()"

Parameters:

variable - in a JEXL context

expression - where # is a place holder for the variable

Returns:

the transformed expression
