All Implemented Interfaces:

ZeroResults

public final class InitExpr
extends Expr<InitAction>
implements ZeroResults

This class implements a init expression. This expression will never return any results, as we are running the initialiser on an object, not constructing a new one.

InitExpr(Expr<?> f, Expr<?> a)
Creates a new init expression for the specified function and arguments expressions.

Method Summary

InitAction	compileIt() Compiles this expression into an action.
void	resolve(CompilerState state) Resolves any NameExpr in the tree so that they refer to the correct ident.

InitExpr

public InitExpr(Expr<?> f,
                Expr<?> a)

public InitAction compileIt()

Description copied from class: Expr

Compiles this expression into an action.

Specified by:

compileIt in class Expr<InitAction>

Returns:

the Action for this expression

resolve

public void resolve(CompilerState state)

Description copied from class: Expr

Resolves any NameExpr in the tree so that they refer to the correct ident. e.g. This method is responsible for ensuring that references to a function argument in the body of a function actually refer to the correct value.

Specified by:

resolve in class Expr<InitAction>

Parameters:

state - the compiler state we are resolving in
