Class SqlProcessResult

java.lang.Object
  org.sqlproc.engine.impl.SqlProcessResult

All Implemented Interfaces:

Comparable<SqlProcessResult>

public class SqlProcessResult
extends Object
implements Comparable<SqlProcessResult>

Holds the results of ANSI SQL query generation. The result is related to the overall ANSI SQL Query generation in SqlMetaStatement or the partial processing result in SqlMetaElement.process(SqlProcessContext). The main runtime contract is setQueryParams(SqlSession, SqlQuery).
