      • ArrayPrimitiveStore

        public ArrayPrimitiveStore​(java.lang.Class<?> clazz,
                           int size)
        Constructs a new store. The supplied clazz must be a primitive type such as int.class.
        Parameters:

      • getType

        public java.lang.Class<?> getType()
        Description copied from interface: ValueStore
        Returns the class of value which this object can store.
        Specified by:
        getType in interface ValueStore
        Returns:
        primitive class

      • getLength

        public long getLength()
        Description copied from interface: ValueStore
        Returns the length of the vector.
        Specified by:
        getLength in interface ValueStore
        Returns:
        vector length

      • put

        public void put​(long index,
                java.lang.Object array,
                int ioff,
                int count)
        Description copied from interface: ValueStore
        Stores a vector of values in this object. array must be an array of values matching getType. Element ioff of array is stored at index index, elemnt ioff+1 at index+1, etc.
        Specified by:
        put in interface ValueStore
        Parameters:
        index - starting offset to write to
        array - array of values to store
        ioff - offset into array from which the first value is taken
        count - number of values to transfer

      • get

        public void get​(long index,
                java.lang.Object array,
                int ioff,
                int count)
        Description copied from interface: ValueStore
        Retrieves a vector of values from this object. array must be an array of type matching getType. Every element of array will be filled with values; the first retrieved from offset index, the second from index+1, etc.
        Specified by:
        get in interface ValueStore
        Parameters:
        index - starting offset
        array - array to accept data
