BeanModelDataSourceFactory

public BeanModelDataSourceFactory(java.lang.ClassLoader classLoader)

Constructor for the factory that produces bean modelling datasources. This will load datasources from the given classloader.

Parameters:

classLoader - the classloader to load datasources from

Method Detail

addAdditionalDataSource

public boolean addAdditionalDataSource(java.net.URL datasourceJarURL)

Adds an extra URL to the factory, so that additional datasources can be loaded from outside the current classloader. createDataSources() will then generate datasources for all datasources found in the current classloader or jar files at the additional urls specified.

Parameters:

datasourceJarURL - the url to load additional datasources from

Returns:

true if the add operation succeeds

removeAdditionalDataSource

public boolean removeAdditionalDataSource(java.net.URL datasourceJarURL)

Removes a URL to the factory, so that additional datasources will not be loaded from outside the current classloader. createDataSources() will generate datasources for all datasources found in the current classloader or jar files at the additional urls specified, but no longer including this one.

Parameters:

datasourceJarURL - the url to remove from datasources generation

Returns:

true if the remove operation succeeds

clearAdditionalDataSources

public void clearAdditionalDataSources()

Clears the set of urls from which additional datasources are loaded

getFactoryClassLoader

public java.lang.ClassLoader getFactoryClassLoader()

Returns the classloader this factory is currently configured with. Any datasources found in this classloader will be included in datasource creation

Returns:

the classloader for this factory

getAdditionalDataSources

public java.util.Set<java.net.URL> getAdditionalDataSources()

Returns the list of urls that is currently configured as additional datasource locations

Returns:

the currently configured list of additional datasources

createDataSources

public java.util.Set<DataSource> createDataSources()
                                            throws DataSourceException

Creates all datasources found either in the current classloader or at any of the additional locations specified by getAdditionalDataSources().

Returns:

the set of datasources generated

Throws:

DataSourceException - if there is a problem generating new datasources
