            throws Exception

Constructor creates and initializes the meta data object create DS object per table

Parameters:

tableNames - - String array of database table names ,It can be zero element array

singleService - - select the service generation mode true one service for whole database when it false services per table wise

dataSourceId - - carbon datasource id it can be null When create the connection there are 3 away to do it , First way is provide the relevant information(url, driver, username, password) which need to create connection that time other fields(connection, datasourceId) should be null Second way directly you can provide connection instance final way is you can provide carbon datasource id(name) if you wish to use all the tables of database you can provide zero element array

Throws:

Exception
