Constructor Summary

Real(float[] array)
Deprecated. use the pool methods: aquire instance and release instance instead

Deprecated. use the pool methods: aquire instance and release instance instead

Method Summary

Real	add(Real a)
static Real	aquireDirtyInstance(int size) returns a real from the pooled instances, the real that is returned is not zeroed, so should only be used where the contents are about to be overwritten.
static Real	aquireInstance(int size) returns a real from the pooled instances, the real that is returned is zeroed, so is identical to instanciation by the constructor Real(int size).

Method Detail

aquireInstance

public static Real aquireInstance(int size)

returns a real from the pooled instances, the real that is returned is zeroed, so is identical to instanciation by the constructor Real(int size). Remember to return the instance back to the pool with releaseInstance

Parameters:

size -

Returns:

aquireDirtyInstance

public static Real aquireDirtyInstance(int size)

returns a real from the pooled instances, the real that is returned is not zeroed, so should only be used where the contents are about to be overwritten. Rememeber to return the instance back to the pool with releaseInstance

Parameters:

size -

Returns:

releaseInstance

public static void releaseInstance(Real instance)

releases the instance of the Real back into the object pool.

Parameters:

instance -

size

public int size()

get

public float get(int index)

set

public void set(Real other)

setZero

public void setZero()

fill

public void fill(float value)

add

public Real add(Real a)

sub

public Real sub(Real a)

Parameters:

a -

Returns:

this

scale

public void scale(float scale)

dot

public float dot(Real a)

dot

public float dot(RealPointer a)

norm

public float norm()

normalize

public void normalize()

length

public float length()

lengthSquared

public float lengthSquared()

min

public float min()

returns the minumum value among the components

Returns:

max

public float max()

returns the maximum value among the components

Returns:

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

epsilonEquals

public static boolean epsilonEquals(Real a,
                                    Real b,
                                    float e)

set

public void set(int index,
                float value)

epsilonEquals

public static boolean epsilonEquals(float a,
                                    float b,
                                    float e)
