Parameters:

s - the arithmetic symbol to make an expression for

a - the left hand side integer

b - the right hand side expression, which should return a single result

Method Detail

newAction

public UnaryOpAction newAction(Action a)

Description copied from class: UnaryOpExpr

Compiles this expression into an action. This is method performs the expression specific compilation, but does not need to handle the single expression compilation.

Specified by:

newAction in class UnaryOpExpr<UnaryOpAction>

Parameters:

a - the compiled single expression

Returns:

the Action for this expression
