      public ResettableArrayCache(ArrayCache arrayCache)
      Creates a new ResettableArrayCache based on the given ArrayCache.

  • Method Details

    • getByteArray

      public byte[] getByteArray(int size, boolean fillWithZeros)
      Description copied from class: ArrayCache
      Allocates a new byte array.

      This implementation simply returns new byte[size].

      Overrides:
      getByteArray in class ArrayCache
      Parameters:
      size - the minimum size of the array to allocate; an implementation may return an array that is larger than the given size
      fillWithZeros - if true, the caller expects that the first size elements in the array are zero; if false, the array contents can be anything, which speeds things up when reusing a cached array

    • putArray

      public void putArray(byte[] array)
      Description copied from class: ArrayCache
      Puts the given byte array to the cache. The caller must no longer use the array.

      This implementation does nothing.

      Overrides:
      putArray in class ArrayCache

    • getIntArray

      public int[] getIntArray(int size, boolean fillWithZeros)
      Description copied from class: ArrayCache
      Allocates a new int array.

      This implementation simply returns new int[size].

      Overrides:
      getIntArray in class ArrayCache
      Parameters:
      size - the minimum size of the array to allocate; an implementation may return an array that is larger than the given size
      fillWithZeros - if true, the caller expects that the first size elements in the array are zero; if false, the array contents can be anything, which speeds things up when reusing a cached array

    • putArray

      public void putArray(int[] array)
      Description copied from class: ArrayCache
      Puts the given int array to the cache. The caller must no longer use the array.

      This implementation does nothing.

      Overrides:
      putArray in class ArrayCache

    • reset

      public void reset()
      Puts all allocated arrays back to the underlying ArrayCache that haven't already been put there with a call to putArray.
