- All Implemented Interfaces:
ConfigurationBuilderProvider
public class MultiFileConfigurationBuilderProvider extends BaseConfigurationBuilderProvider
A specialized
ConfigurationBuilderProvider
implementation for integratingMultiFileConfigurationBuilder
withCombinedConfigurationBuilder
.When using a configuration source managed by
MultiFileConfigurationBuilder
it is not sufficient to store the configuration once obtained from the builder in the resulting combined configuration. Rather, it has to be ensured that each access to this configuration queries the builder anew so that it can evaluate its file pattern and return a different configuration if necessary. Therefore, this class returns a specialized wrapper over aMultiFileConfigurationBuilder
which returns a configuration wrapping the builder; so accessing the configuration's properties actually calls back to the builder. This constellation is compatible with the wayDynamicCombinedConfiguration
manages its data.- Since:

public MultiFileConfigurationBuilderProvider(java.lang.String configCls, java.lang.String paramCls)
Creates a new instance ofMultiFileConfigurationBuilderProvider

getConfigurationBuilder
public ConfigurationBuilder<? extends Configuration> getConfigurationBuilder(ConfigurationDeclaration decl) throws ConfigurationException
Gets the builder for the configuration source managed by this provider. This method is called during processing of the combined configuration definition file. This implementation delegates to some protected methods to create a new builder instance using reflection and to configure it with parameter values defined by the passed inBeanDeclaration
. This implementation lets the super class create a fully configured builder. Then it returns a special wrapper around it.- Specified by:

in interfaceConfigurationBuilderProvider
- Overrides:

- Parameters:
decl
- the bean declaration with initialization parameters for the configuration builder- Returns:
- the
ConfigurationBuilder
object created by this provider - Throws:
ConfigurationException
