java.lang.Object
weka.core.expressionlanguage.common.SimpleVariableDeclarations.VariableInitializer
All Implemented Interfaces:
Serializable
Enclosing class:
SimpleVariableDeclarations
public static class SimpleVariableDeclarations.VariableInitializer extends Object implements Serializable
A class to initialize variables that have been declared by a SimpleVariableDeclarations class and used inside a program

Note that not all variables declared can be initialized!
Particularly variables that have been declared but are never used inside a program can't be initialized.

Then variable values that are expensive to compute don't have to be computed if the values are never used inside a program.
