          Description

Interface Summary
NSArray.Operator Objects implementing NSArray.Operator are used to perform operations on an array's elements.
NSCoding The NSCoding interface declares the methods that a class must implement so that instances of that class can be encoded and decoded.
NSDisposable The NSDisposable interface declares one method, dispose, in which an object prepares for destruction.
NSKeyValueCoding The NSKeyValueCoding interface defines a data transport mechanism in which the properties of an object are accessed indirectly by name (or key), rather than directly through invocation of an accessor method or as instance variables.
NSKeyValueCoding.ErrorHandling The NSKeyValueCoding.ErrorHandling interface declares an API for handling errors that occur during key-value coding.
NSKeyValueCodingAdditions The NSKeyValueCodingAdditions interface defines an extension to the basic NSKeyValueCoding interface.
NSLocking The NSLocking interface declares the elementary methods adopted by classes that define lock objects.
NSValidation The NSValidation interface defines a validation mechanism in which the properties of an object are validated indirectly by name (or key), rather than directly through invocation of an specific validation method.
 

Class Summary
NSArray NSArray and its subclass NSMutableArray manage ordered collections of objects.
NSBundle An NSBundle represents a location in the file system that groups code and resources that can be used in a program.
NSCoder NSCoder is an abstract class that declares the API used by concrete subclasses to transfer objects and other data items between memory and some other format.
NSCoding.Support NSCoding.Support is an abstract class that defines a mechanism for one class to provide NSCoding behavior on behalf of another class.
NSComparator NSComparator is an abstract class that defines an API for comparing two objects for the purpose of sorting them.
NSData NSData and its subclass NSMutableData provide data objects, object-oriented wrappers for byte buffers.
NSDelayedCallbackCenter An NSDelayedCallbackCenter object (also called a delayed callback center) provides a way to guarantee that particular methods are invoked after an event has ended.
NSDictionary The NSDictionary class declares an API for objects that manage immutable associations of keys and values.
NSDisposableRegistry A NSDisposableRegistry object is a registry of NSDisposable objects that should be disposed when the registry is disposed.
NSKeyValueCoding.DefaultImplementation The NSKeyValueCoding.DefaultImplementation class provides the WebObjects default implementations of the NSKeyValueCoding and NSKeyValueCoding.ErrorHandling interfaces.
NSKeyValueCoding.Null NSKeyValueCoding.Null is a final class that defines a unique object used to represent null values in collection objects, such as NSArrays, which do not allow null values.
NSKeyValueCoding.Utility The NSKeyValueCoding.Utility class is a convenience that allows you to access the properties of NSKeyValueCoding objects and non-NSKeyValueCoding objects using the same code.
NSKeyValueCoding.ValueAccessor NSKeyValueCoding.ValueAccessor is an abstract class that establishes a mechanism by which NSKeyValueCoding can operate on object's package access instance variables.
NSKeyValueCodingAdditions.DefaultImplementation The NSKeyValueCodingAdditions.DefaultImplementation class provides default implementations of the NSKeyValueCodingAdditions interface.
NSKeyValueCodingAdditions.Utility The NSKeyValueCodingAdditions.Utility class is a convenience that allows one to access the properties of NSKeyValueCodingAdditions objects and non-NSKeyValueCodingAdditions objects using the same code.
NSLock An NSLock object is used to coordinate the operation of multiple threads of execution within the same application.
NSLog NSLog is a static class that is used to access the WebObjects Foundation logging system.
NSLog.Logger NSLog.Logger is an abstract class that specifies the core functionality for NSLog.
NSLog.PrintStreamLogger NSLog.PrintStreamLogger is a concrete subclass of NSLog.Logger.
NSMultiReaderLock The NSMultiReaderLock class provides reader and writer locks.
NSMutableArray The NSMutableArray class provides facilities for managing a mutable collection of objects.
NSMutableData The NSMutableData class declares the programmatic interface to an object that contains modifiable data in the form of bytes.
NSMutableDictionary The NSMutableDictionary class adds methods to insert, modify, and remove elements to the API of its parent class NSDictionary
NSMutableRange An NSMutableRange is an object representing a range that can be changed.
NSMutableSet NSMutableSet provides support for the mathematical concept of a set which, unlike its parent NSSet, may have members added or removed after its creation.
NSNotification NSNotification objects encapsulate information so that it can be broadcast to other objects by an NSNotificationCenter object.
NSNotificationCenter An NSNotificationCenter object (or simply, notification center) is essentially a notification dispatch table.
NSNumberFormatter NSNumberFormatter converts between java.lang.Number and textual representations of numeric values.
NSPathUtilities This class provides static methods that are useful when working with paths.
NSProperties This class extends Java's properties mechanism to merge application properties with the standard system properties available using the java.lang.System.getProperties method.
NSPropertyListSerialization This class provides static methods that convert between property lists and their string representations, which can be either strings or NSData objects.
NSRange An NSRange represents a range, a measurement of a segment of something linear, such as a byte stream.
NSRecursiveLock NSRecursiveLock defines a lock that may be acquired multiple times by the same thread without causing a deadlock (a situation where a thread is permanently blocked waiting for itself to relinquish a lock).
NSSelector An NSSelector object specifies a method signature (a method's name and parameter list).
NSSet NSSet declares an API for an object that manages a collection of objects similar to a mathematical set.
NSSocketUtilities This class provides an easy way to get a TCP socket (java.net.Socket) with a connection timeout.
NSTimestamp NSTimestamp objects represent a particular instant in time.
NSTimestamp.IntRef Deprecated. in the Java Foundation framework.
NSTimestampFormatter Instances of NSTimestampFormatter format NSTimestamps into their textual representations and convert textual representations of dates and times into NSTimestamps.
NSTimeZone NSTimeZone defines the behavior of time zones for different geopolitical regions.
NSUndoManager NSUndoManager is a general-purpose recorder of operations for undo and redo.
NSValidation.DefaultImplementation The methods in the NSValidation.DefaultImplementation class are just like the methods defined by the NSValidation interface, except they are static methods and they take an additional argument, which is the object on which the default implementation should operate.
NSValidation.Utility This class is a convenience that allows you to access the properties of NSValidation objects and non-NSValidation objects using the same code.
 

Exception Summary
NSComparator.ComparisonException Instances of the NSComparator.ComparisonException class are created and thrown when an error condition is encountered during the comparison of two objects.
NSForwardException NSForwardException objects (or forwarded exceptions) are wrappers for Throwable objects which are not RuntimeExceptions.
NSKeyValueCoding.UnknownKeyException Instances of the NSKeyValueCoding.UnknownKeyException class are created and thrown when an unknown key is encountered during key-value coding.
NSValidation.ValidationException Instances of the NSValidation.ValidationException class are created and thrown when an error condition is encountered during the validation of an object that implements NSValidation.

Introduction

The Foundation framework defines a base layer of classes written in Java. In addition to providing a set of useful primitive object classes, it introduces several paradigms that define functionality not covered by the Java language. The Foundation framework is designed with these goals in mind:

Foundation Framework Classes

The Foundation framework consists of several related groups of classes as well as a few individual classes:
