Constructor Detail

RUByteArray

public RUByteArray(int chunkSize)

Creates an array in which the initial capacity is set the same as the chunk size.

RUByteArray

public RUByteArray(int initialCapacity,
                   int chunkSize)

Creates an array with the given initial capacity and chunk size.

Parameters:

initialCapacity - The number of elements in the storage array

chunkSize - The number of storage elements that will be added each time the storage array grows.
