Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this object.
boolean	equals(Object obj) Indicates whether some other object is "equal to" this one.
void	finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
final Class<?>	getClass() Returns the runtime class of this `Object`.
int	hashCode() Returns a hash code value for the object.
final void	notify() Wakes up a single thread that is waiting on this object's monitor.
final void	notifyAll() Wakes up all threads that are waiting on this object's monitor.
String	toString() Returns a string representation of the object.
final void	wait() Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
final void	wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
final void	wait(long timeout) Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.

Protected Constructors

protected GraphicsPrimitive (String methodSignature, int primTypeID, SurfaceType sourceType, CompositeType compositeType, SurfaceType destType)

Create a new GraphicsPrimitive with all of the required descriptive information.

protected GraphicsPrimitive (long pNativePrim, String methodSignature, int primTypeID, SurfaceType sourceType, CompositeType compositeType, SurfaceType destType)

Create a new GraphicsPrimitive for native invocation with all of the required descriptive information.

Public Methods

public final CompositeType getCompositeType ()

public final SurfaceType getDestType ()

public final long getNativePrim ()

public final int getPrimTypeID ()

Gets unique id for this GraphicsPrimitive type. This id is used to identify the TYPE of primitive (Blit vs. BlitBg) as opposed to INSTANCE of primitive.

Returns

primitive ID

public final String getSignature ()

public final SurfaceType getSourceType ()

public final int getUniqueID ()

Gets instance ID of this graphics primitive. Instance ID is comprised of four distinct ids (ORed together) that uniquely identify each instance of a GraphicsPrimitive object. The four ids making up instance ID are: 1. primitive id - identifier shared by all primitives of the same type (eg. all Blits have the same primitive id) 2. sourcetype id - identifies source surface type 3. desttype id - identifies destination surface type 4. compositetype id - identifies composite used

Returns

instance ID

public static final synchronized int makePrimTypeID ()

public abstract GraphicsPrimitive makePrimitive (SurfaceType srctype, CompositeType comptype, SurfaceType dsttype)

public static final synchronized int makeUniqueID (int primTypeID, SurfaceType src, CompositeType cmp, SurfaceType dst)

public final boolean satisfies (String signature, SurfaceType srctype, CompositeType comptype, SurfaceType dsttype)

Return true if this primitive can be used for the given signature surfaces, and composite.

Parameters

signature	The signature of the given operation. Must be == (not just .equals) the signature string given by the abstract class that declares the operation.
srctype	The surface type for the source of the operation
comptype	The composite type for the operation
dsttype	The surface type for the destination of the operation

public static String simplename (Field[] fields, Object o)

public static String simplename (CompositeType ct)

public static String simplename (SurfaceType st)

public String toString ()

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())

Returns

a string representation of the object.
