loadError

public boolean loadError(Throwable th)

Description copied from interface: ConfigLoaderDelegate

Gives delegate an opportunity to process the error.

Specified by:

loadError in interface ConfigLoaderDelegate

Returns:

boolean indicating whether ConfigLoader should proceed with further processing. Ultimately it is up to the ConfigLoader to make this decision.

shouldLoadProjectVersion

public void shouldLoadProjectVersion(String version)

Description copied from interface: ConfigLoaderDelegate

Callback method invoked when a project version is read.

Specified by:

shouldLoadProjectVersion in interface ConfigLoaderDelegate

Since:

1.1

shouldRegisterDataView

public void shouldRegisterDataView(String name,
                                   String location)

Description copied from interface: ConfigLoaderDelegate

Callback method invoked when a DataView reference is encountered in the configuration file.

Specified by:

shouldRegisterDataView in interface ConfigLoaderDelegate

Since:

1.1

shouldLoadDataDomainProperties

public void shouldLoadDataDomainProperties(String domainName,
                                           Map<String,String> properties)

Specified by:

shouldLoadDataDomainProperties in interface ConfigLoaderDelegate

shouldLoadDataDomain

public void shouldLoadDataDomain(String domainName)

Description copied from interface: ConfigLoaderDelegate

Callback method invoked when a domain is encountered in the configuration file.

Specified by:

shouldLoadDataDomain in interface ConfigLoaderDelegate

Parameters:

domainName - domain name.

shouldLoadDataMaps

public void shouldLoadDataMaps(String domainName,
                               Map<String,DataMap> locations)

Specified by:
