EvalEnv (morel 0.2.0 API)

All Known Subinterfaces:

MutableEvalEnv

All Known Implementing Classes:

EvalEnvs.MapEvalEnv, EvalEnvs.MutableSubEvalEnv, EvalEnvs.SubEvalEnv
```
public interface EvalEnv
```
Evaluation environment.
Whereas Environment contains both types and values, because it is used for validation/compilation, EvalEnv contains only values.

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`default EvalEnv`	`bind(java.lang.String name, java.lang.Object value)`	Creates an environment that has the same content as this one, plus the binding (name, value).
`default MutableEvalEnv`	`bindMutable(java.lang.String name)`	Creates an evaluation environment that has the same content as this one, plus a mutable slot.
`java.lang.Object`	`getOpt(java.lang.String name)`	Returns the binding of `name` if bound, null if not.
`default java.util.Map<java.lang.String,java.lang.Object>`	`valueMap()`	Returns a map of the values and bindings.
`void`	`visit(java.util.function.BiConsumer<java.lang.String,java.lang.Object> consumer)`	Visits every variable binding in this environment.

- Method Detail
  - getOpt
```
java.lang.Object getOpt(java.lang.String name)
```
    Returns the binding of name if bound, null if not.
  - bind
```
default EvalEnv bind(java.lang.String name,
                     java.lang.Object value)
```
    Creates an environment that has the same content as this one, plus the binding (name, value).
  - bindMutable
```
default MutableEvalEnv bindMutable(java.lang.String name)
```
    Creates an evaluation environment that has the same content as this one, plus a mutable slot.
  - visit
```
void visit(java.util.function.BiConsumer<java.lang.String,java.lang.Object> consumer)
```
    Visits every variable binding in this environment.
    Bindings that are obscured by more recent bindings of the same name are visited, but after the more obscuring bindings.
  - valueMap
```
default java.util.Map<java.lang.String,java.lang.Object> valueMap()
```
    Returns a map of the values and bindings.
