Variable.Global

java.lang.Object
- org.jscience.mathematics.function.Variable.Global<X>

All Implemented Interfaces:

javolution.lang.Reference<X>, Variable<X>

Enclosing interface:

Variable<X>
```
public static class Variable.Global<X>
extends java.lang.Object
implements Variable<X>
```
This class represents a simple Variable implementation with context-local values. Instances of this class can be set independently by multiple-threads as long as each concurrent thread executes within a LocalContext. For example:[code] public abstract class Engine { public static final Variable.Global> RPM = new Variable.Global>("rpm"); public abstract Function, Amount> getTorque(); } ... LocalContext.enter(); try { RPM.set(rpm); Amount torque = myEngine.getTorque().evaluate(); } finally { LocalContext.exit(); }[/code] It should be noted that parameterized evaluations are performed within a local context. Therefore, the example above could also be rewritten:[code] Amount torque = myEngine.getTorque().evaluate(rpm); [/code]
