All Implemented Interfaces:

Runnable, Environmental, Initializable, Op, Ops.Eval, NullaryFunctionOp<Object>, UnaryFunctionOp<String,Object>, NullaryOp<Object>, Output<Object>, SpecialOp, UnaryInput<String>, UnaryOp<String,Object>, Threadable, Command, SciJavaPlugin
```
public class DefaultEval
extends AbstractUnaryFunctionOp<String,Object>
implements Ops.Eval
```
Evaluates an expression.
The expression is parsed using Parsington, the SciJava expression parsing library, then evaluated by invoking available ops.
