an Optional containing the profile content and position within in the application.yaml

mergeProfiles

public static String mergeProfiles(String existingProfile,
 String newProfile,
 List<String> toBeRemoved)

Merges an existing profile with a new profile. A merge includes the following steps:

1. Parse existing and new profile into properties

newProfile - the new profile content

toBeRemoved - a list with properties to be removed

Returns:

the enhanced profile content

replaceProfile

public static String replaceProfile(String yamlContent,
 int[] boundaries,
 String newProfile)

writeDeep

public static void writeDeep(Map<String,Object> tree,
 String[] pathSegments,
 Object value)

Parameters:

profile - content of a single profile

Returns:

the flattened properties of the profile
