Class SimpleVariableDeclarations.VariableInitializer

  • All Implemented Interfaces:
    java.io.Serializable
    Enclosing class:
    SimpleVariableDeclarations
    public static class SimpleVariableDeclarations.VariableInitializer
extends java.lang.Object
implements java.io.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.
