Detailed Description

The protocol which all root classes implement.

Method Documentation

- (id) autorelease

Adds the object to the topmost OFAutoreleasePool of the thread's autorelease pool stack.

Returns

The object

- (Class) class

Returns the class of the object.

Returns

The class of the object

Reimplemented in OFObject.

- (bool) conformsToProtocol:

(Protocol *)

protocol

Checks whether the object conforms to the specified protocol.

Parameters

protocol

The protocol which should be checked for conformance

Returns

A boolean whether the object conforms to the specified protocol

Reimplemented in OFObject.

- (uint32_t) hash

Calculates a hash for the object.

Classes containing data (like strings, arrays, lists etc.) should reimplement this!

Warning

If you reimplement this, you also need to reimplement isEqual: to behave in a way compatible to your reimplementation of this method!

Returns

A 32 bit hash for the object

Reimplemented in <OFHash>.

- (bool) isEqual:

(nullable id)

object

Checks two objects for equality.

Classes containing data (like strings, arrays, lists etc.) should reimplement this!

Warning

If you reimplement this, you also need to reimplement hash to return the same hash for objects which are equal!

Parameters

object

The object which should be tested for equality

Returns

A boolean whether the object is equal to the specified object

- (bool) isKindOfClass:

(Class)

class_

Returns a boolean whether the object of the specified kind.

Parameters

class_

The class whose kind is checked

Returns

A boolean whether the object is of the specified kind

- (bool) isMemberOfClass:

(Class)

class_

Returns a boolean whether the object is a member of the specified class.

Parameters

class_

The class for which the receiver is checked

Returns

A boolean whether the object is a member of the specified class

- (bool) isProxy

Returns whether the object is a proxy object.

Returns

A boolean whether the object is a proxy object

- (nullable IMP) methodForSelector:

(SEL)

selector

Returns the implementation for the specified selector.

Parameters

selector

The selector for which the method should be returned

Returns

The implementation for the specified selector

- (nullable id) performSelector:

(SEL)

selector

Performs the specified selector.

Parameters

selector

The selector to perform

Returns

The object returned by the method specified by the selector

- (nullable id) performSelector:		(SEL)	selector
withObject:		(nullable id)	object

Performs the specified selector with the specified object.

Parameters

selector	The selector to perform
object	The object that is passed to the method specified by the selector

Returns

The object returned by the method specified by the selector

- (nullable id) performSelector:		(SEL)	selector
withObject:		(nullable id)	object1
withObject:		(nullable id)	object2

Performs the specified selector with the specified objects.

Parameters

selector	The selector to perform
object1	The first object that is passed to the method specified by the selector
object2	The second object that is passed to the method specified by the selector

Returns

The object returned by the method specified by the selector

- (void) release

Decreases the retain count.

Each time an object is released, the retain count gets decreased and the object deallocated if it reaches 0.

Reimplemented in OFAutoreleasePool.

- (bool) respondsToSelector:

(SEL)

selector

Returns a boolean whether the object responds to the specified selector.

Parameters

selector

The selector which should be checked for respondance

Returns

A boolean whether the objects responds to the specified selector

- (id) retain

Increases the retain count.

Each time an object is released, the retain count gets decreased and the object deallocated if it reaches 0.

- (unsigned int) retainCount

Returns the retain count.

Returns

The retain count

- (id) self

Returns the receiver.

Returns

The receiver

- (Class) superclass

Returns the superclass of the object.

Returns

The superclass of the object

Reimplemented in OFObject.

- (nullable const char*) typeEncodingForSelector:

(SEL)

selector

Returns the type encoding for the specified selector.

Parameters

selector

The selector for which the type encoding should be returned

Returns

The type encoding for the specified selector
