Method Detail

isKeyword

public static boolean isKeyword(java.lang.String id,
                                LanguageLevel level)

isSoftKeyword

public static boolean isSoftKeyword(java.lang.CharSequence id,
                                    LanguageLevel level)

start

public final void start(java.lang.CharSequence buffer,
                        int startOffset,
                        int endOffset,
                        int initialState)

Description copied from class: Lexer

Prepare for lexing character data from buffer passed. Internal lexer state is supposed to be initialState. It is guaranteed that the value of initialState is the same as returned by Lexer.getState() method of this lexer at condition startOffset=getTokenStart(). This method is used to incrementally re-lex changed characters using lexing data acquired from this particular lexer sometime in the past.

Specified by:

start in class Lexer

Parameters:

buffer - character data for lexing.

startOffset - offset to start lexing from

endOffset - offset to stop lexing at

initialState - the initial state of the lexer.

getState

public int getState()

Description copied from class: Lexer

Returns the current state of the lexer.

Specified by:

getState in class Lexer

Returns:

the lexer state.

getTokenType

public final IElementType getTokenType()

Description copied from class: Lexer

Returns the token at the current position of the lexer or null if lexing is finished.

Specified by:

getTokenType in class Lexer

Returns:

the current token.

getTokenStart

public final int getTokenStart()

Description copied from class: Lexer

Returns the start offset of the current token.

Specified by:

getTokenStart in class Lexer

Returns:

the current token start offset.

getTokenEnd

public final int getTokenEnd()

Description copied from class: Lexer

Returns the end offset of the current token.

Specified by:

getTokenEnd in class Lexer

Returns:

the current token end offset.

advance

public final void advance()

Description copied from class: Lexer

Advances the lexer to the next token.

Specified by:

advance in class Lexer

getBufferSequence

public java.lang.CharSequence getBufferSequence()

Description copied from class: Lexer

Returns the buffer sequence over which the lexer is running. This method should return the same buffer instance which was passed to the start() method.

Specified by:

getBufferSequence in class Lexer

Returns:

the lexer buffer.

getBufferEnd

public final int getBufferEnd()

Description copied from class: Lexer

Returns the offset at which the lexer will stop lexing. This method should return the length of the buffer or the value passed in the endOffset parameter to the start() method.

Specified by:

getBufferEnd in class Lexer

Returns:

the lexing end offset
