public class EOCocoaUtilities

extends Object

EOcocoaUtilities is a class of static methods aimed at making it easy to use the pure java implementation of EOF with Apple's "bridged Java" Cocoa technology.

Method Summary

static com.apple.cocoa.foundation.NSGregorianDate	gregorianDateForTimestamp(NSTimestamp timestamp)
static void	registerCocoaSet() Registers EOCocoaSetPlugin as the widget set for the EOInterface layer to use and the default WidgetPlugins for use with their associations and widgets.
static void	releaseObject(Object object) Ensures that object is available to have its Objective-C handle freed.
static void	retainObject(Object object) Ensures that object does not have it's handle (which lives on the Objective-C side of the bridge) freed by the bridge.
static NSTimestamp	timestampForGregorianDate(com.apple.cocoa.foundation.NSGregorianDate date)

Method Detail

gregorianDateForTimestamp

public static com.apple.cocoa.foundation.NSGregorianDate gregorianDateForTimestamp(NSTimestamp timestamp)

Parameters:

timestamp - NSTimestamp instance used to create a new NSGregorianDate

Returns:

NSGregorianDate instance that represents the time that the NSTimestamp, timestamp, represents

See Also:

timestampForGregorianDate(NSGregorianDate date).

registerCocoaSet

public static void registerCocoaSet()

Registers EOCocoaSetPlugin as the widget set for the EOInterface layer to use and the default WidgetPlugins for use with their associations and widgets. Also loads all Cocoa framework bundles used in the application

releaseObject

public static void releaseObject(Object object)

Ensures that object is available to have its Objective-C handle freed.

Parameters:

object - the object to be released; object must be non-null and should be an object that had been retained with retainObject

See Also:

retainObject(Object object)

retainObject

public static void retainObject(Object object)

Ensures that object does not have it's handle (which lives on the Objective-C side of the bridge) freed by the bridge. Once you are done with the object, you should release it with releaseObject.

Parameters:

object - the object to be retained; object must be non-null

See Also:

releaseObject(Object object)

timestampForGregorianDate

public static NSTimestamp timestampForGregorianDate(com.apple.cocoa.foundation.NSGregorianDate date)

Parameters:

date - NSGregorianDate instance used to create a new NSTimestamp

Returns:

NSTimestamp instance that represents the time that the NSGregorianDate, date, represents

See Also:

gregorianDateForTimestamp(NSTimestamp timestamp).
