Method Details

reallocateBuffer

public static <T> T[] reallocateBuffer(Class<T> klass,
 T[] oldBuffer,
 int oldCapacity,
 int newCapacity)

Reallocate a buffer.

reallocateBuffer

public static int[] reallocateBuffer(int[] oldBuffer,
 int oldCapacity,
 int newCapacity)

Reallocate a buffer.

reallocateBuffer

public static float[] reallocateBuffer(float[] oldBuffer,
 int oldCapacity,
 int newCapacity)

Reallocate a buffer.

reallocateBuffer

public static <T> T[] reallocateBuffer(Class<T> klass,
 T[] buffer,
 int userSuppliedCapacity,
 int oldCapacity,
 int newCapacity,
 boolean deferred)

Reallocate a buffer. A 'deferred' buffer is reallocated only if it is not NULL. If 'userSuppliedCapacity' is not zero, buffer is user supplied and must be kept.

reallocateBuffer

public static int[] reallocateBuffer(int[] buffer,
 int userSuppliedCapacity,
 int oldCapacity,
 int newCapacity,
 boolean deferred)

Reallocate an int buffer. A 'deferred' buffer is reallocated only if it is not NULL. If 'userSuppliedCapacity' is not zero, buffer is user supplied and must be kept.

reallocateBuffer

public static float[] reallocateBuffer(float[] buffer,
 int userSuppliedCapacity,
 int oldCapacity,
 int newCapacity,
 boolean deferred)

Reallocate a float buffer. A 'deferred' buffer is reallocated only if it is not NULL. If 'userSuppliedCapacity' is not zero, buffer is user supplied and must be kept.

rotate

public static <T> void rotate(T[] ray,
 int first,
 int new_first,
 int last)

Rotate an array, see std::rotate

rotate

public static void rotate(int[] ray,
 int first,
 int new_first,
 int last)

Rotate an array, see std::rotate

rotate

public static void rotate(float[] ray,
