Get the names of the columns in the bank. The name is used in the calls getInt() and getDouble() and other calls for get the arrays.

Returns:

array of strings with names.

getDescriptor

DataDescriptor getDescriptor()

Returns the descriptor of the bank, that contains names of the variables and their types.

Returns:

bank descriptor

getDouble
