get

double get(int i)

Gets element from vector by index and cast it to double.

Parameters:

i - Vector element index.

Returns:

Value obtained for given element index.

getRaw

Type Parameters:

T - Type of stored element in vector.

Parameters:

i - Vector element index.

Returns:

Value obtained for given element index.

set

void set(int i,
         double v)

Parameters:

i - Vector element index.

v - Value to set at given index.

setRaw

void setRaw(int i,
            Serializable v)

Parameters:

i - Vector element index.
