Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`default boolean`	`isEquivalentTo(Expression other)`	Returns whether this expression will accept the same values as another.
`default Expression`	`negate()`	Returns the negation of this expression, equivalent to not(this).
`Expression.Operation`	`op()`	Returns the operation for an expression node.

- Method Detail
  - op
```
Expression.Operation op()
```
    Returns the operation for an expression node.
  - negate
```
default Expression negate()
```
    Returns the negation of this expression, equivalent to not(this).
  - isEquivalentTo
```
default boolean isEquivalentTo(Expression other)
```
    Returns whether this expression will accept the same values as another.
    If this returns true, the expressions are guaranteed to return the same evaluation for the same input. However, if this returns false the expressions may return the same evaluation for the same input. That is, expressions may be equivalent even if this returns false.
    For best results, rewrite not and bind expressions before calling this method.
    
    Parameters:
    
    other - another expression
    
    Returns:
    
    true if the expressions are equivalent
