Class JMEUtil

Method Details

• growArray

  public static int[] growArray(int[] array, int newSize)

• copyArray

  public static int[] copyArray(int[] array)

• growArray

  public static <T> T[] growArray(T[] array, int newSize)

• copyOf

  public static <T> T[] copyOf(T[] original, int newLength)

  Copies the specified array, truncating or padding with nulls (if necessary) so the copy has the specified length. For all indices that are valid in both the original array and the copy, the two arrays will contain identical values. For any indices that are valid in the copy but not the original, the copy will contain null. Such indices will exist if and only if the specified length is greater than that of the original array. The resulting array is of exactly the same class as the original array.

  Type Parameters:

  T - the class of the objects in the array

  Parameters:

  original - the array to be copied

  newLength - the length of the copy to be returned

  Returns:

  a copy of the original array, truncated or padded with nulls to obtain the specified length

  Throws:

  NegativeArraySizeException - if newLength is negative

  NullPointerException - if original is null

  Since:

  1.6

• copyOf

  public static <T, U> T[] copyOf(U[] original, int newLength, Class<? extends T[]> newType)

  Copies the specified array, truncating or padding with nulls (if necessary) so the copy has the specified length. For all indices that are valid in both the original array and the copy, the two arrays will contain identical values. For any indices that are valid in the copy but not the original, the copy will contain null. Such indices will exist if and only if the specified length is greater than that of the original array. The resulting array is of the class newType.

  Type Parameters:

  T - the class of the objects in the returned array

  U - the class of the objects in the original array

  Parameters:

  original - the array to be copied

  newLength - the length of the copy to be returned

  newType - the class of the copy to be returned

  Returns:

  a copy of the original array, truncated or padded with nulls to obtain the specified length

  Throws:

  NegativeArraySizeException - if newLength is negative

  NullPointerException - if original is null

  ArrayStoreException - if an element copied from original is not of a runtime type that can be stored in an array of class newType
