 class SqlProcessContext
extends java.lang.Object

The crate (design pattern) for all input parameters for SqlMetaStatement.process(org.sqlproc.engine.impl.SqlMetaStatement.Type, Object, Object, List, Map) . Also can work as a context for a dynamic ANSI SQL Query generation. This processing is based on the contract SqlMetaElement.process(SqlProcessContext).
