Check if we should use multiple threads to scan for annotations or not

Parameters:

context - the context of the multi threaded setting

Returns:

true if multi threading is enabled on the context, server, or via a System property.

See Also:

MULTI_THREADED

getMaxScanWait

protected int getMaxScanWait(WebAppContext context)

Work out how long we should wait for the async scanning to occur.

Parameters:

context - the context of the max scan wait setting

Returns:

the max scan wait setting on the context, or server, or via a System property.

See Also:

MAX_SCAN_WAIT

Configure an instance of a WebAppContext, based on a template WebAppContext that has previously been configured by this Configuration.

Specified by:

cloneConfigure in interface Configuration

Overrides:

cloneConfigure in class AbstractConfiguration

Parameters:
