Class ReportFactory

java.lang.Object

org.faceless.publisher.ReportFactory

public class ReportFactory
extends Object

A ReportFactory is used to create Report objects.

A single instance of the factory may be used in multiple threads to create multiple Reports, in which case they will all share the same cache of external resources such as stylesheetlist, images and fonts.

Or, different instances of this factory may be created which are entirely independent.

The factory can be used to create a Report from a File or URL, or a new Report object can be returned which can be parsed externally

Return the cache size as set by setCacheSize(int)

Returns:

the cache-size

getResourceCache

public Map<URL2,Resource> getResourceCache()

Returns:

the SecureRandom object

setRandom

public void setRandom(SecureRandom random)

Set the SecureRandom object to be used for any random numbers required during parsing - this is used mainly for network requests for resources. The default is the native non-blocking PRNG random generator, which is normally the best choice.
