Constructor Detail

AntlrToken

public AntlrToken(org.antlr.v4.runtime.Token token,
                  AntlrToken previousComment,
                  TextDocument textDoc)

Constructor

Parameters:

token - The antlr token implementation

previousComment - The previous comment

textDoc - The text document

Method Detail

getNext

public AntlrToken getNext()

Description copied from interface: GenericToken

Obtain the next generic token according to the input stream which generated the instance of this token.

Specified by:

getNext in interface GenericToken<AntlrToken>

Returns:

the next generic token if it exists; null if it does not exist

getPreviousComment

public AntlrToken getPreviousComment()

Description copied from interface: GenericToken

Obtain a comment-type token which, according to the input stream which generated the instance of this token, precedes this instance token and succeeds the previous generic token (if there is any).

Specified by:

getPreviousComment in interface GenericToken<AntlrToken>

Returns:

the comment-type token if it exists; null if it does not exist

getImageCs

public CharSequence getImageCs()

Description copied from interface: GenericToken

Returns the text of the token as a char sequence. This should be preferred when you can use eg StringUtils to do some processing, without having to create a string.

Specified by:

getImageCs in interface GenericToken<AntlrToken>

getRegion

public TextRegion getRegion()

Returns a text region with the coordinates of this token.

Specified by:

getRegion in interface GenericToken<AntlrToken>

getReportLocation

public FileLocation getReportLocation()

Description copied from interface: Reportable

Returns the location at which this element should be reported.

Use this instead of Node.getBeginColumn()/Node.getBeginLine(), etc.

Specified by:

getReportLocation in interface Reportable

isEof

public boolean isEof()

Description copied from interface: GenericToken

Returns true if this token is an end-of-file token. This is the last token of token sequences that have been fully lexed.

Specified by:

isEof in interface GenericToken<AntlrToken>

compareTo

public int compareTo(AntlrToken o)

Description copied from interface: GenericToken

This must return true if this token comes before the other token. If they start at the same index, then the smaller token comes before the other.

Specified by:

compareTo in interface Comparable<AntlrToken>

Specified by:

compareTo in interface GenericToken<AntlrToken>

getKind

public int getKind()

Description copied from interface: GenericToken

Gets a unique integer representing the kind of token this is. The semantics of this kind depend on the language.

The returned constants can be looked up in the language's "*ParserConstants", e.g. CppParserConstants or JavaParserConstants. These constants are considered internal API and may change at any time when the language's grammar is changed.

Specified by:

getKind in interface GenericToken<AntlrToken>

isHidden

public boolean isHidden()

isDefault

public boolean isDefault()
