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 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.
