All Implemented Interfaces:

OneResult

public final class FnCompExpr
extends BinaryOpExpr<FnCompAction>

This class implements a compound function expression. A compound function expression has a left and right hand side function, the left hand side is executed first, then the right hand side is executed with the results of the left hand side as arguments. e.g.

rhs( lhs( args...) )

FnCompExpr

public FnCompExpr(java.lang.String n,
                  Expr<?> a,
                  Expr<?> b)

Creates a new compound function expression with the specified name and component function expressions.

Parameters:

n - the name for the compound function expression

a - the left hand side component function expression

b - the right hand side component function expression

Method Detail

newAction

public FnCompAction newAction(Action a,
                              Action b)

Description copied from class: BinaryOpExpr

Compiles this expression into an action. This is method performs the expression specific compilation, but does not need to handle the left and right hand side expression compilation.

Specified by:

newAction in class BinaryOpExpr<FnCompAction>

Parameters:

a - the compiled left hand side expression

b - the compiled right hand side expression

Returns:

the Action for this expression
