    • Method Detail

      • put

        @Deprecated() <T> void put(T array, Class<T> arrayClass)

        Optionally adds the given array of the given type to the pool.

        Arrays may be ignored, for example if the array is larger than the maximum size of the pool.

      • put

         synchronized <T> void put(T array)

        Optionally adds the given array of the given type to the pool.

        Arrays may be ignored, for example if the array is larger than the maximum size of the pool.

      • getExact

         synchronized <T> T getExact(int size, Class<T> arrayClass)

        Returns a non-null array of the given type with a length exactly equal to the given size.

        If an array of the given size isn't in the pool, a new one will be allocated.

        This class makes no guarantees about the contents of the returned array.

      • get

         synchronized <T> T get(int size, Class<T> arrayClass)

        Returns a non-null array of the given type with a length >= to the given size.

        If an array of the given size isn't in the pool, a new one will be allocated.

        This class makes no guarantees about the contents of the returned array.

      • clearMemory

         synchronized void clearMemory()

        Clears all arrays from the pool.
