Method Detail

simplify

public Expression simplify()

Description copied from class: Expression

Simplify an expression which occurs in a call (non-nested) position.

Specified by:

simplify in class Expression

Returns:

The simplified expression

argify

public Expression.Arg argify()

Description copied from class: Expression

Simplify an expression which occurs in an argument (nested) position. Returns an Arg, which produces an Argument for the simplified call, and may also introduce a binder, in the case of a nested expression. The default behavior is to act as a nested expression and produce a complexArg. Expressions which can validly occur in arg position on their own without a binder will override this behavior.

Overrides:

argify in class Expression

Returns:

The argified form of the expression

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

accept

public <E> E accept(Visitor<E> visitor)
