        Creates a new ResettableArrayCache based on the given ArrayCache.

    • Method Detail

      • 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.
