+	(BOOL)	exchangeClassMethod:	(SEL) sel1
	withMethod:		(SEL) sel2

Swap a pair of class methods of the underlying class.

in objc/Nu.h

+	(BOOL)	exchangeInstanceMethod:	(SEL) sel1
	withMethod:		(SEL) sel2

Swap a pair of instance methods of the underlying class.

in objc/Nu.h

(id)

inheritedByClass:

(NuClass *) newClass

This method is automatically sent to a class whenever Nu code creates a subclass of that class. Its default implementation does nothing. Override it to track subclassing.

in objc/Nu.h

(BOOL)

include:

(NuClass *) prototypeClass

Copy all of the instance methods from a specified class to the receiving class.

in objc/Nu.h

+	(BOOL)	copyInstanceMethod:	(NSString *) methodName
	fromClass:		(NuClass *) prototypeClass

Copy a named instance method from another class to the receiving class.

in objc/Nu.h

(id)

createSubclassNamed:

(NSString *) subclassName

Create a subclass of a class with the specified name.

in objc/Nu.h

(NSArray *)

instanceVariableNames

Get an array containing the names of all instance variables of the class.

in objc/Nu.h

(NSArray *)

instanceMethodNames

Get an array containing the names of the instance methods of a class.

in objc/Nu.h

(NSArray *)

classMethodNames

Get an array containing the names of the class methods of a class.

in objc/Nu.h

(NSArray *)

instanceMethods

Get an array containing NuMethod representations of the instance methods of a class.

in objc/Nu.h

(NSArray *)

classMethods

Get an array containing NuMethod representations of the class methods of a class.

in objc/Nu.h

(NSData *)

binaryPropertyListRepresentation

Property list helper. Return the binary property list representation of the object.

in objc/Nu.h

(NSData *)

XMLPropertyListRepresentation

Property list helper. Return the XML property list representation of the object.

in objc/Nu.h

(BOOL)

hasValueForIvar:

(NSString *) name

Return true if object has a value for the named instance variable.

in objc/Nu.h

(void)

removeAssociatedObjects

Remove all associated objects.

in objc/Nu.h

(id)

associatedObjectForKey:

(id) key

Get the value of an associated object.

in objc/Nu.h

-	(void)	setCopiedAssociatedObject:	(id) object
	forKey:		(id) key

Set a copied associated object.

in objc/Nu.h

-	(void)	setAssignedAssociatedObject:	(id) object
	forKey:		(id) key

Set an assigned associated object.

in objc/Nu.h

-	(void)	setRetainedAssociatedObject:	(id) object
	forKey:		(id) key

Set a retained associated object.

in objc/Nu.h

(id)

set:

(NuCell *) propertyList

Concisely set key-value pairs from a property list.

in objc/Nu.h

(NSString *)

help

Get a string providing a helpful description of an object. This method should be overridden by subclasses to be more helpful.

in objc/Nu.h

-	(id)	handleUnknownMessage:	(id) cdr
	withContext:		(NSMutableDictionary *) context

Handle an unknown message. Override this in subclasses to provide dynamic method handling.

in objc/Nu.h

-	(id)	evalWithArguments:	(id) cdr
	context:		(NSMutableDictionary *) context

Evaluate a list with the receiving object at the head. Calls sendMessage:withContext:

in objc/Nu.h

-	(id)	sendMessage:	(id) cdr
	withContext:		(NSMutableDictionary *) context

Send a message to an object with an execution context

in objc/Nu.h

-	(void)	setValue:	(id) value
	forIvar:		(NSString *) name

Sets the value of a specified instance variable.

in objc/Nu.h

(id)

valueForIvar:

(NSString *) name

Gets the value of a specified instance variable.

in objc/Nu.h

(id)

evalWithContext:

(NSMutableDictionary *) context

Evaluation operator. The Nu default is for an Objective-C object to evaluate to itself, but certain subclasses (such as NuSymbol and NSString) behave differently.

in objc/Nu.h

(bool)

atom

Returns true. In Nu, virtually all Objective-C classes are considered atoms.

in objc/Nu.h

(id)

onlyMatchingChild:

(id) block

Return one object from the object child-hierarchy rooted at the current object. The object must match criteria in the provided block. For example, to return the NSButton object in a specified view, use:

(myView onlyMatchingChild: (do (v) (v isKindOfClass: NSButton)))

Return a collection of objects from the object child-hierarchy rooted at the current object. Objects must match criteria in the provided block. For example, to return all the NSButton objects in a specified view, use:

(myView allMatchingChildren: (do (v) (v isKindOfClass: NSButton)))

in nu/nibtools.nu

(id)

children

Get the children of an object. By default, NSObjects have no children.

in nu/nibtools.nu
