Class Tuple4b

java.lang.Object
  extended by javax.media.ding3d.vecmath.Tuple4b
All Implemented Interfaces:
java.io.Serializable, java.lang.Cloneable
Direct Known Subclasses:
Color4b

public abstract class Tuple4b
extends java.lang.Object
implements java.io.Serializable, java.lang.Cloneable

A four byte tuple. Note that Java defines a byte as a signed integer in the range [-128, 127]. However, colors are more typically represented by values in the range [0, 255]. Java 3D recognizes this and, in those cases where Tuple4b is used to represent color, treats the bytes as if the range were [0, 255]---in other words, as if the bytes were unsigned. Values greater than 127 can be assigned to a byte variable using a type cast. For example:

If intValue is greater than 127, then byteVariable will be negative. The correct value will be extracted when it is used (by masking off the upper bits).

Constructor Detail

Tuple4b

public Tuple4b(byte b1,
               byte b2,
               byte b3,
               byte b4)
Constructs and initializes a Tuple4b from the specified four values.

Parameters:
b1 - the first value
b2 - the second value
b3 - the third value
b4 - the fourth value

Tuple4b

public Tuple4b(byte[] t)
Constructs and initializes a Tuple4b from the array of length 4.

Parameters:
t - the array of length 4 containing b1 b2 b3 b4 in order

Tuple4b

public Tuple4b(Tuple4b t1)
Constructs and initializes a Tuple4b from the specified Tuple4b.

Parameters:
t1 - the Tuple4b containing the initialization x y z w data

Tuple4b

public Tuple4b()
Constructs and initializes a Tuple4b to (0,0,0,0).

Method Detail

toString

public java.lang.String toString()
Returns a string that contains the values of this Tuple4b.

Overrides:
toString in class java.lang.Object
Returns:
the String representation

get

public final void get(byte[] b)
Places the value of the x,y,z,w components of this Tuple4b into the array of length 4.

Parameters:
b - array of length 4 into which the values are placed

get

public final void get(Tuple4b t1)
Places the value of the x,y,z,w components of this Tuple4b into the tuple t1.

Parameters:
t1 - tuple into which the values are placed

set

public final void set(Tuple4b t1)
Sets the value of the data members of this tuple to the value of the argument tuple t1.

Parameters:
t1 - the source tuple

set

public final void set(byte[] b)
Sets the value of the data members of this tuple to the value of the array b of length 4.

Parameters:
b - the source array of length 4

equals

public boolean equals(Tuple4b t1)
Returns true if all of the data members of tuple t1 are equal to the corresponding data members in this tuple.

Parameters:
t1 - the tuple with which the comparison is made

equals

public boolean equals(java.lang.Object t1)
Returns true if the Object t1 is of type Tuple4b and all of the data members of t1 are equal to the corresponding data members in this Tuple4b.

Overrides:
equals in class java.lang.Object
Parameters:
t1 - the object with which the comparison is made

hashCode

public int hashCode()
Returns a hash code value based on the data values in this object. Two different Tuple4b objects with identical data values (i.e., Tuple4b.equals returns true) will return the same hash code value. Two objects with different data members may return the same hash value, although this is not likely.

Overrides:
hashCode in class java.lang.Object
Returns:
the integer hash code value
