Detailed Description

This is the execution context for a query. It contains the parameter bindings so as to make query execution thread-safe.

Definition at line 45 of file QueryExecutionContextImpl.java.

Constructor & Destructor Documentation

com.mysql.clusterj.core.query.QueryExecutionContextImpl.QueryExecutionContextImpl ( SessionSPI  session )

inline

Create a new execution context with an empty map of parameters.

Parameters

session

the session for this context

Definition at line 68 of file QueryExecutionContextImpl.java.

Here is the call graph for this function:

Create a new execution context copying the bound parameter values. This allows a new execution of a query only modifying some parameters.

Parameters

context

an existing execution context

Definition at line 80 of file QueryExecutionContextImpl.java.

com.mysql.clusterj.core.query.QueryExecutionContextImpl.QueryExecutionContextImpl ( SessionSPI  session, Map< String, Object >  parameterMap  )

inline

Create a new execution context with specific map of parameters.

Parameters

session	the session for this context
parameterMap	the parameter map for this context

Definition at line 89 of file QueryExecutionContextImpl.java.
