getConfig

C getConfig(C proxy)

getConfig

C getConfig(String namespace,
            String key)

Parameters:

namespace - as String

key - as String

Returns:

getAll

Map<K,T> getAll(String namespace)

Get a Map of key name and corresponding AbstractConfiguration for the specific namespace.
The key in the returned map, is the full key name including namespace, to avoid local key name conflicts in the returned map.
Note that namespaces are assumed to follow a delimited convention defined by ConfigurationSource.NAMESPACE_DELIM This method respects hierarchy based on default convention.
If namespace does not exist or namespace is null then null is returned. Note: param matching is case insensitive

Parameters:

namespace - as String

Returns:

Map of key and corresponding AbstractConfiguration

getConfigs

List<C> getConfigs(String namespace)

Get configurations for a namespace and nested namesapces, as a collection of C

Parameters:

namespace - as String

Returns:

Collection of C

getNamespaces

List<String> getNamespaces()

Get list of namespaces

Returns:

List of String

delete

void delete(C config)

Remove a configuration

Specified by:
