javax.vecmath.Tuple4b
- All Implemented Interfaces:
Serializable
,Cloneable
- Direct Known Subclasses:
Color4b
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:
- byteVariable = (byte) intValue; // intValue can be > 127

-
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

toString
Returns a string that contains the values of this Tuple4b. -
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
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
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
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
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. -
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. -
clone
