Constructor Details

Value

public Value(Group parent,
 String key)

Creates a new instance of Value.

Parameters:

parent - The parent group.

key - The key.

Value

public Value(Group parent,
 String key,
 String value)

Creates a new instance of Value.

Parameters:

parent - The parent group.

addComment

public final void addComment(String comment)

Adds a comment to the value.

Parameters:

checkKeyCandidate

@API(status=INTERNAL,
     since="0.4.4")
public static final boolean checkKeyCandidate(String candidate)

An implementation of Predicate to be used with Objects.requireValidArgument(Object,String,Predicate) when checking the keys for new values.

The candidate may not begin with a hash symbol ('#') or an opening bracket ('['), and it may not contain newline characters, tab characters or equal signs.

You should avoid hash symbols and opening brackets completely, even inside or at the end of the key, as well as closing brackets (']'), despite they are technically valid.

Parameters:

candidate - The key to check.

Returns:

true if the value is a valid key, false otherwise.

Throws:

NullArgumentException - The candidate is null.

EmptyArgumentException - The candidate is the empty string.

BlankArgumentException - The candidate consists of whitespace only.

Since:

0.4.4
