Method Detail

getSource

public Source getSource(java.lang.String location,
                        java.util.Map parameters)
                 throws java.io.IOException,
                        java.net.MalformedURLException

Description copied from interface: SourceFactory

Get a Source object. The factory creates a new Source object that can be used by the application. However, when this source object is not needed anymore it has to be released again using the SourceFactory.release(Source) method. This is achieved by using SourceResolver.release(Source) which finds the appropriate SourceFactory.

Specified by:

getSource in interface SourceFactory

Parameters:

location - The URI to resolve - this URI includes the scheme.

parameters - additionnal named parameters (optionnal and can be null) that drive the creation of the Source object. Each implementation must specify what parameters it accepts.

Returns:

the created source object.

Throws:

java.io.IOException - if the source couldn't be created for some reason.

java.net.MalformedURLException
