Interface EPFireAndForgetService

All Known Implementing Classes:

EPFireAndForgetServiceImpl

public interface EPFireAndForgetService

Executes fire-and-forget non-continuous on-demand queries against named windows or tables.

Compile queries use the compile-query methods of the compiler.

Method Summary

Modifier and Type	Method and Description
com.espertech.esper.common.client.fireandforget.EPFireAndForgetQueryResult	executeQuery(com.espertech.esper.common.client.EPCompiled compiled) Execute a fire-and-forget query.
com.espertech.esper.common.client.fireandforget.EPFireAndForgetQueryResult	executeQuery(com.espertech.esper.common.client.EPCompiled compiled, com.espertech.esper.common.client.context.ContextPartitionSelector[] selectors) Execute a fire-and-forget query for use with named windows and tables that have a context declared and that may therefore have multiple context partitions, allows to target context partitions for query execution selectively.

Method Detail

executeQuery

com.espertech.esper.common.client.fireandforget.EPFireAndForgetQueryResult executeQuery(com.espertech.esper.common.client.EPCompiled compiled)

Execute a fire-and-forget query.

Parameters:

compiled - is the compiled EPL query to execute

Returns:

query result

executeQuery

com.espertech.esper.common.client.fireandforget.EPFireAndForgetQueryResult executeQuery(com.espertech.esper.common.client.EPCompiled compiled,
                                                                                        com.espertech.esper.common.client.context.ContextPartitionSelector[] selectors)

Execute a fire-and-forget query for use with named windows and tables that have a context declared and that may therefore have multiple context partitions, allows to target context partitions for query execution selectively.

Parameters:

compiled - is the compiled EPL query to execute

selectors - selects context partitions to consider

Returns:

result

prepareQuery

com.espertech.esper.common.client.fireandforget.EPFireAndForgetPreparedQuery prepareQuery(com.espertech.esper.common.client.EPCompiled compiled)

Prepare an unparameterized fire-and-forget query before execution and for repeated execution.

Parameters:

compiled - is the compiled EPL query to prepare

Returns:

proxy to execute upon, that also provides the event type of the returned results

prepareQueryWithParameters

com.espertech.esper.common.client.fireandforget.EPFireAndForgetPreparedQueryParameterized prepareQueryWithParameters(com.espertech.esper.common.client.EPCompiled compiled)

Prepare a parameterized fire-and-forget query for repeated parameter setting and execution. Set all values on the returned holder then execute using executeQuery(EPFireAndForgetPreparedQueryParameterized).

Parameters:

compiled - is the compiled EPL query to prepare

Returns:

parameter holder upon which to set values

executeQuery

com.espertech.esper.common.client.fireandforget.EPFireAndForgetQueryResult executeQuery(com.espertech.esper.common.client.fireandforget.EPFireAndForgetPreparedQueryParameterized parameterizedQuery)

Execute a fire-and-forget parameterized query.

Parameters:

parameterizedQuery - contains the query and parameter values

Returns:

query result

com.espertech.esper.common.client.fireandforget.EPFireAndForgetQueryResult executeQuery(com.espertech.esper.common.client.fireandforget.EPFireAndForgetPreparedQueryParameterized parameterizedQuery,
                                                                                        com.espertech.esper.common.client.context.ContextPartitionSelector[] selectors)

Execute a fire-and-forget parameterized query.

Parameters:

parameterizedQuery - contains the query and parameter values

selectors - selects context partitions to consider

Returns:

query result
