Method Detail

create

public static IProperties create(IProperties.IMapper mapper)

Creates an empty IProperties set with an optional property mapper.

Parameters:

mapper - [may be null]

Returns:

an empty property set [never null]

wrap

public static IProperties wrap(java.util.Properties properties,
                               IProperties.IMapper mapper)

Converts a java.util.Properties instance to an IProperties instance, with an optional property mapper. Note that 'properties' content is shallowly cloned, so the result can be mutated independently from the input.

Parameters:

properties - [may not be null]

mapper - [may be null]

Returns:

a property set based on 'properties' [never null]

combine

public static IProperties combine(IProperties overrides,
                                  IProperties base)

Combines two property sets by creating a property set that chains 'overrides' to 'base' for property delegation. Note that 'overrides' are cloned defensively and so the result can be mutated independently of both inputs.

Parameters:

overrides - [may be null]

base - [may be null]

Returns:

[never null; an empty property set with a null mapper is created if both inputs are null]
