Constructor Detail

ServiceConfigurationConfigSource

protected ServiceConfigurationConfigSource()

Creates a new ServiceConfigurationConfigSource.

The name of this ServiceConfigurationConfigSource will be equal to the value of the system property named by concatenating this ServiceConfigurationConfigSource's simple class name converted to lowercase with .serviceIdentifier, or, if that is null, the simple class name converted to lowercase itself.

See Also:

ServiceConfigurationConfigSource(ServiceConfiguration)

ServiceConfigurationConfigSource

protected ServiceConfigurationConfigSource(ServiceConfiguration serviceConfiguration)

Creates a new ServiceConfigurationConfigSource.

Parameters:

serviceConfiguration - the ServiceConfiguration this ServiceConfigurationConfigSource will wrap. If this parameter is null, then the service identifier for which to find a ServiceConfiguration will be determined by first trying to use the value of the system property named by concatenating this ServiceConfigurationConfigSource's simple class name converted to lowercase with .serviceIdentifier, and then, if that is null (as it commonly may be) by simply using this ServiceConfigurationConfigSource's simple class name converted to lowercase. The result of invoking ServiceConfiguration.getInstance(String) on this value will then be used as if it had been passed directly.

ServiceConfiguration.getInstance(String), ServiceConfiguration.getServiceIdentifier()

getProperties

public final Map<String,String> getProperties()

Returns a Map representing all properties known to this ServiceConfigurationConfigSource.

The Map that is returned is immutable and thread-safe.

Specified by:

getProperties in interface ConfigSource

Returns:

a Map representing all properties known to this ServiceConfigurationConfigSource; never null

getValue

public final String getValue(String name)

Returns the value of the property identified by the supplied name, or null if there is no such property or a value could not be found for some reason.

This method may return null.

This method returns the result of invoking the ServiceConfiguration.getProperty(String) method with the supplied name.

Specified by:

getValue in interface ConfigSource

Parameters:

name - the name of the property; may be null in which case null will be returned

Returns:

a value for the named property, or null
