Class Drag

java.lang.Object
  |
  +--com.apple.mrj.dnd.Drag

Direct Known Subclasses:

IncomingDrag, OutgoingDrag

Deprecated. As of MacOSX 10.2, replaced by Java2 DnD.

public abstract class Drag

extends Object

An abstract common base class for all drags; the concrete subclasses are IncomingDrag and OutgoingDrag. Drag represents the data being transferred and the connection between the source and destination of the data. OutgoingDrag adds the ability to add data and to start the drag operation, while IncomingDrag lets the receiver specify whether the data was accepted and what the drop location is.

static void	check(short result) Deprecated.
void	dispose() Deprecated. Marks this Drag as no longer usable.
boolean	equals(Drag d) Deprecated.
boolean	equals(Object o) Deprecated. Indicates whether some other object is "equal to" this one.
DataFlavor	findItemFlavor(int index, DataFlavor[] flavors) Deprecated. Utility that determines whether an item contains at least one of the given flavors and returns the first of the given flavors that it finds, otherwise zero.
Object	getDestination() Deprecated. Returns the drag's current destination (the object under the mouse.) If the drag has not yet been tracked, this will return null.
boolean	getHasLeftSource() Deprecated. Returns true if a drag being tracked has ever moved outside its source.
boolean	getInsideSenderWindow() Deprecated. Returns true if the drag is in the window it originated in.
Transferable	getItem(int index) Deprecated. Returns a drag item by index.
int	getItemCount() Deprecated. Returns the number of items being dragged.
int	getRef() Deprecated. Returns the Drag Manager DragRef ID for this drag operation.
Object	getSource() Deprecated. Returns the object that initiated the drag, if known.
int	hashCode() Deprecated. Returns a hash code value for the object.
boolean	isDisposed() Deprecated.
boolean	isDropAccepted() Deprecated. Returns true if the drop has been accepted by the receiver.

Method Detail

dispose

public void dispose()

Deprecated.

Marks this Drag as no longer usable.

isDisposed

public boolean isDisposed()

Deprecated.

getRef

public int getRef()

Deprecated.

Returns the Drag Manager DragRef ID for this drag operation.

equals

public boolean equals(Drag d)

Deprecated.

equals

public boolean equals(Object o)

Deprecated.

Description copied from class: Object

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation:

• It is reflexive: for any reference value x, x.equals(x) should return true.
• It is symmetric: for any reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
• It is transitive: for any reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
• It is consistent: for any reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the object is modified.
• For any non-null reference value x, x.equals(null) should return false.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any reference values x and y, this method returns true if and only if x and y refer to the same object (x==y has the value true).

Parameters:

obj - the reference object with which to compare.

Returns:

true if this object is the same as the obj argument; false otherwise.

Boolean.hashCode(), Hashtable

hashCode

public int hashCode()

Deprecated.

Description copied from class: Object

Returns a hash code value for the object. This method is supported for the benefit of hashtables such as those provided by java.util.Hashtable.

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
• If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
• It is not required that if two objects are unequal according to the Object.equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hashtables.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java^TM programming language.)

Overrides:

hashCode in class Object

Following copied from class: java.lang.Object

Returns:

a hash code value for this object.

getItemCount

public int getItemCount()

Deprecated.

Returns the number of items being dragged. Each item has one or more flavors, or alternate data types.

getItem

public Transferable getItem(int index)

Deprecated.

Returns a drag item by index.

allItemsContainFlavors

public boolean allItemsContainFlavors(DataFlavor[] flavors)

Deprecated.

Utility that returns true if all of the items in the drag contain at least one of the flavors in the given array. This is an easy way to test whether an incoming drag can be accepted by a receiver that can handle a particular set of flavors.

findItemFlavor

public DataFlavor findItemFlavor(int index,
                                 DataFlavor[] flavors)

Deprecated.

Utility that determines whether an item contains at least one of the given flavors and returns the first of the given flavors that it finds, otherwise zero.

Parameters:

item - The item index

flavors - The list of acceptable flavors

isDropAccepted

public boolean isDropAccepted()

Deprecated.

Returns true if the drop has been accepted by the receiver. This will not be valid (it'll just return false) until the receiver's done handling the drop.

getInsideSenderWindow

public boolean getInsideSenderWindow()

Deprecated.

Returns true if the drag is in the window it originated in.

getSource

public Object getSource()

Deprecated.

Returns the object that initiated the drag, if known. If the drag was initiated from an AWT component in the same Java VM, that Component instance will be returned.

If the source is in another application, null will be returned.

getDestination

public Object getDestination()

Deprecated.

Returns the drag's current destination (the object under the mouse.) If the drag has not yet been tracked, this will return null.

getHasLeftSource

public boolean getHasLeftSource()

Deprecated.

Returns true if a drag being tracked has ever moved outside its source. (This determines whether the current destination should display a highlight frame.)

check

public static void check(short result)

Deprecated.

toString

public String toString()

Deprecated.

Description copied from class: Object

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 

Overrides:

toString in class Object

Following copied from class: java.lang.Object

Returns:

a string representation of the object.
