AbstractQuery

protected AbstractQuery()

Creates a new query object.

Method Details

setMaxQueryTime

@Deprecated
public void setMaxQueryTime(int maxQueryTimeSeconds)

Deprecated.

Description copied from interface: Query

Specifies the maximum time that a query is allowed to run. The query will be interrupted when it exceeds the time limit. Any consecutive requests to fetch query results will result in QueryInterruptedExceptions.

Specified by:

setMaxQueryTime in interface Query

Parameters:

maxQueryTimeSeconds - The maximum query time, measured in seconds. A negative or zero value indicates an unlimited query time (which is the default).

getMaxQueryTime

@Deprecated
public int getMaxQueryTime()

Deprecated.

Description copied from interface: Query

Returns the maximum query evaluation time.

Specified by:

getMaxQueryTime in interface Query

Returns:

The maximum query evaluation time, measured in seconds.
