Class DefaultStatementFactory

java.lang.Object
  com.syrtsov.ddao.factory.DefaultStatementFactory

All Implemented Interfaces:

StatementFactory

public class DefaultStatementFactory
extends java.lang.Object
implements StatementFactory

DefaultStatementFactory creates new prepared statment using simplified IBATIS like query syntax:
value reference can be put using number that reflect 0 based method argument number that will be used as simle value (and as such can not be java bean or any other non trivial object) or it can be name of java bean property or Map object that is 1st argument in the list of method arguments. Query paramter can be added as inline value by enclosing it in '$' or it can be added as bound value by enclosing it in '#'. Inline value will be injected in query text before query will be passed to JDBC connection. Bound value will be bound to prepared statement before it's execution.
