Constructor Detail

AGDelegationCreation

public AGDelegationCreation(ATSymbol sel,
                            ATTable args)

Method Detail

meta_eval

public ATObject meta_eval(ATContext ctx)
                   throws InterpreterException

To evaluate a first-class delegation message creation AG element, transform the selector and evaluated arguments into a first-class NATDelegation object. It is important to note that the arguments are all eagerly evaluated. AGDEL(sel,arg).eval(ctx) = NATDEL(sel, map eval(ctx) over arg )

Specified by:

meta_eval in interface ATObject

Overrides:

meta_eval in class NATNil

Returns:

a first-class delegating message send

Throws:

InterpreterException

protected ATObject newQuoted(ATSymbol quotedSel,
                             ATTable quotedArgs)

Description copied from class: AGMessageCreation

Subclasses must implement this method in order to return a new instance of themselves parameterized with their quoted arguments.

Specified by:

newQuoted in class AGMessageCreation

getMessageToken

protected java.lang.String getMessageToken()

Description copied from class: AGMessageCreation

Subclasses must implement this method such that the correct messaging token can be displayed when printing an AGMessageCreation element.

Specified by:
