Method Details

getPlusIndentCommentsBefore

public Indent getPlusIndentCommentsBefore()

How much extra to indent comments before the Token.

Returns:

the extra indent

breakAndIndentTrailingComment

public Optional<Indent> breakAndIndentTrailingComment()

Force a line break and indent trailing javadoc or block comments.

make

public static Op make(Input.Token token,
 Token.RealOrImaginary realOrImaginary,
 Indent plusIndentCommentsBefore,
 Optional<Indent> breakAndIndentTrailingComment)

Make a Token.

Parameters:

token - the Input.Token to wrap

realOrImaginary - did this Input.Token appear in the input, or was it generated incorrectly?

plusIndentCommentsBefore - extra plusIndent for comments just before this token

Returns:

the new Token

getToken

public Input.Token getToken()

Return the wrapped Input.Token.

Returns:

the Input.Token

realOrImaginary

public Token.RealOrImaginary realOrImaginary()

Is the token good? That is, does it match an Input.Token?

Returns:

whether the @code Token} is good

add
