Method Details

getFlex

public FlexLexer getFlex()

start

public void start(@NotNull
 @NotNull CharSequence buffer,
 int startOffset,
 int endOffset,
 int initialState)

Description copied from interface: 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 interface 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 interface: Lexer

Returns the current state of the lexer.

Specified by:

getState in interface Lexer

Returns:

the lexer state.

getTokenType

public IElementType getTokenType()

Description copied from interface: Lexer

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

Specified by:

getTokenType in interface Lexer

Returns:

the current token.

getTokenStart

public int getTokenStart()

Description copied from interface: Lexer

Returns the start offset of the current token.

Specified by:

getTokenStart in interface Lexer

Returns:

the current token start offset.

getTokenEnd

public int getTokenEnd()

Description copied from interface: Lexer

Returns the end offset of the current token.

Specified by:

getTokenEnd in interface Lexer

Returns:

the current token end offset.

advance

public void advance()

Description copied from interface: Lexer

Advances the lexer to the next token.

Specified by:

advance in interface Lexer

getBufferSequence

@NotNull
public @NotNull CharSequence getBufferSequence()

Description copied from interface: 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 interface Lexer

Returns:

the lexer buffer.

getBufferEnd

public int getBufferEnd()

Description copied from interface: 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 interface Lexer

Returns:

the lexing end offset

locateToken

protected void locateToken()

toString

public String toString()

Overrides:

toString in class Object
