Returns:

the requested property.

Throws:

IllegalArgumentException - if key is blank.

UnknownPropertyException - if key is not known.

getResolvedProperty

public ResolvedProperty getResolvedProperty(PropertyDescriptor descriptor,
                                            Object defaultValue)

                                            PropertyValidationException

Description copied from interface: ConfigurationProperties

Returns the resolved property for the given descriptor's key, allowing to transparently provide a default value to be returned in case the property has not been set.

Specified by:

getResolvedProperty in interface ConfigurationProperties

Parameters:

descriptor - descriptor key to the property.

defaultValue - the default value to use in case no value has been specified.

Returns:

the resolved property. Never null, although the value / resolved value of the returned property may be null.

Throws:

IllegalArgumentException - if key is blank.

UnknownPropertyException - if key is not known.

PropertyValidationException - if the property is invalid according to its constraints.

validate

public void validate(boolean lenient)
              throws ConfigurationValidationException

Description copied from interface: ConfigurationProperties

Validates all properties in the given configuration.

Specified by:

validate in interface ConfigurationProperties

Parameters:

lenient - the lenient flag that tells the validation process to handle unknown properties gracefully if set to true. If the value is false unknown properties are reported as validation failures.

Throws:

ConfigurationValidationException - if the configuration contains properties that do not meet the required constraints.

flush

public void flush()

Description copied from interface: ConfigurationPropertiesManagement

Signal to flush properties changed in memory to be written to a secondary storage.

Implementations are not required to only write on a flush. They have to make sure that after the flush is called, all data is transfered to the secondary storage.

Specified by:

flush in interface ConfigurationPropertiesManagement

toSerializable

public SerializableConfigurationPropertiesManagement toSerializable()

Description copied from interface: ConfigurationProperties

Creates a serializable variant of this implementation.

Specified by:

toSerializable in interface ConfigurationProperties

Specified by:

toSerializable in interface ConfigurationPropertiesManagement

Returns:

a serializable variant of this implementation.

                                                 throws NullPointerException

Description copied from interface: ConfigurationPropertiesManagement

Adds the given definitions to this configuration.

Specified by:

addDefinitions in interface ConfigurationPropertiesManagement

Parameters:

properties - the property definitions to add.

Returns:

a reference to this configuration for chaining.

Throws:

NullPointerException - if properties is null.

setProperty

public Property setProperty(PropertyKey key,
                            String value)

Sets the property value for the given key.

This method sets the property in the most defining representative. If the client wants to change a value in a specific defaulting representation by its configuration key, the client has to access this particular instance and set it manually.

Specified by:

setProperty in interface ConfigurationPropertiesManagement

Parameters:

key - the key to the property.

value - the value to the property.

Returns:

the old value to the property. A value of null is returned if the property had no value prior to this call.

Throws:

NullPointerException - if key is null.

Unsets the property value for the given key.

This method unsets the property in the most defining representative. If the client wants to change a value in a specific defaulting representation by its configuration key, the client has to access this particular instance and unset it manually.

Specified by:

unsetProperty in interface ConfigurationPropertiesManagement

Parameters:

key - the key to the property.

Returns:

the old value to the property. A value of null is returned if the property had no value prior to this call.
