EPFireAndForgetService (Esper API Documentation)

```
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

All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`EPFireAndForgetQueryResult`	`executeQuery(EPCompiled compiled)` Execute a fire-and-forget query.
`EPFireAndForgetQueryResult`	`executeQuery(EPCompiled compiled, 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.
`EPFireAndForgetQueryResult`	`executeQuery(EPFireAndForgetPreparedQueryParameterized parameterizedQuery)` Execute a fire-and-forget parameterized query.
`EPFireAndForgetQueryResult`	`executeQuery(EPFireAndForgetPreparedQueryParameterized parameterizedQuery, ContextPartitionSelector[] selectors)` Execute a fire-and-forget parameterized query.
`EPFireAndForgetPreparedQuery`	`prepareQuery(EPCompiled compiled)` Prepare an unparameterized fire-and-forget query before execution and for repeated execution.
`EPFireAndForgetPreparedQueryParameterized`	`prepareQueryWithParameters(EPCompiled compiled)` Prepare a parameterized fire-and-forget query for repeated parameter setting and execution.

```
EPFireAndForgetQueryResult executeQuery(EPCompiled compiled)
```
    Execute a fire-and-forget query.
    
    Parameters:
    
    compiled - is the compiled EPL query to execute
    
    Returns:
    
    query result
  - executeQuery
```
EPFireAndForgetQueryResult executeQuery(EPCompiled compiled,
                                        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
```
EPFireAndForgetPreparedQuery prepareQuery(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
```
EPFireAndForgetPreparedQueryParameterized prepareQueryWithParameters(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
```
EPFireAndForgetQueryResult executeQuery(EPFireAndForgetPreparedQueryParameterized parameterizedQuery)
```
    Execute a fire-and-forget parameterized query.
    
    Parameters:
    
    parameterizedQuery - contains the query and parameter values
    
    Returns:
    
    query result
  - executeQuery
```
EPFireAndForgetQueryResult executeQuery(EPFireAndForgetPreparedQueryParameterized parameterizedQuery,
                                        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
