public class QTPointer
extends QTPointerRef
implements QuickTimeLib, Cloneable
The QTPointer class implements a pointer that can be used in calls to QuickTime.

Constructor Index

o QTPointer(byte[])
Construct a pointer from input data.
o QTPointer(int, boolean)
Allocate a pointer for general use.
o QTPointer(QTHandleRef, int, int)
This constructor is used to create a QTPointer object from a Handle.
o QTPointer(QTPointerRef, QTPointerRef)
Construct a pointer from the concatenation of the two supplied pointers.

Method Index

o clone()
Returns a copy of this object
o concatenate(QTPointerRef)
Concatenates the supplied pointer to this pointer.
o fromEncodedImage(EncodedImage)
Returns EncodedImage data as a QTPointer.
o fromSCData(SoundComponentData)
The buffer that contains the sound data.
o setSize(int)
This method will resize the memory that a pointer points to.

Constructors

o QTPointer 
 public QTPointer(int size,
                  boolean clear) throws QTException
Allocate a pointer for general use.

Parameters:
size - the size of the pointer to create.
clear - clear the pointer upon creation.
o QTPointer 
 public QTPointer(byte byteArray[]) throws QTException
Construct a pointer from input data.

Parameters:
byteArray - the input data.
o QTPointer 
 public QTPointer(QTHandleRef hdl,
                  int offset,
                  int size) throws QTException
This constructor is used to create a QTPointer object from a Handle. The contents of the handle will be copied into the pointer. This will copy size bytes from the handle + offset. It will bounds check the size to be not greater than the size of the handle.

Parameters:
hdl - the handle to copy.
offset - you can specify an offset within the handle from which to copy the data
size - the amount of bytes to copy
o QTPointer 
 public QTPointer(QTPointerRef firstPtr,
                  QTPointerRef secondPtr) throws QTException
Construct a pointer from the concatenation of the two supplied pointers. The First pointer will appear first in the concatentated result.

Parameters:
firstPtr - the first Pointer
secondPtr - the second Pointer

Methods

o fromSCData 
 public static QTPointer fromSCData(SoundComponentData scd)
The buffer that contains the sound data.

Returns:
the QTPointer buffer
See Also:
getBuffer
o fromEncodedImage 
 public static QTPointer fromEncodedImage(EncodedImage image) throws QTException
Returns EncodedImage data as a QTPointer. This will copy the data if the source is an int or byte encoded image, but will return the same object if it is a RawEncodedImage.

Parameters:
image - the encoded image data
Returns:
the encoded image data as a Pointer
o clone 
 public Object clone()
Returns a copy of this object

Overrides:
clone in class Object
o setSize 
 public void setSize(int newSize) throws UtilException
This method will resize the memory that a pointer points to. This operation can fail if memory cannot increase its size

QuickTime::SetPtrSize

Parameters:
newSize - the new size
o concatenate 
 public void concatenate(QTPointerRef ptr) throws UtilException
Concatenates the supplied pointer to this pointer. This operation will fail if unable to resize the pointer.
