public PrefixedConfigurationPropertySource(ConfigurationPropertySource propertiesToPrefix,
 String prefix)

Method Details

get

public Optional<?> get(String key)

Specified by:

get in interface ConfigurationPropertySource

Parameters:

key - The key of the property to get.

Returns:

An optional containing the value of the requested property, or Optional.empty() if the property is missing.

resolve

public Optional<String> resolve(String key)

Specified by:

resolve in interface ConfigurationPropertySource

Parameters:

key - The key of the property to get.

Returns:

An optional containing the key as registered in the underlying configuration source, with any transformation (prefixes, masks) reverted. Whether the optional is empty is not related to the key having a value in the underlying configuration source; instead, the optional is empty only if the key cannot possibly be registered in the underlying configuration source, e.g. if the key is missing a mandatory prefix.

withPrefix

public ConfigurationPropertySource withPrefix(String prefix)

Specified by:

withPrefix in interface ConfigurationPropertySource

Parameters:

prefix - A prefix to prepend to configuration properties.

Returns:

A source containing the same properties as this source, but prefixed with the given prefix plus ".".

toString

public String toString()

Overrides:

toString in class Object
