getMergeFunction

public abstract MergeFunction getMergeFunction()

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

Overrides:

start in class DelegateLexer

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

Overrides:

getState in class DelegateLexer

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

Overrides:

getTokenType in class DelegateLexer

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

Overrides:

getTokenStart in class DelegateLexer

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

Overrides:

getTokenEnd in class DelegateLexer

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

Overrides:

advance in class DelegateLexer

getOriginal

public Lexer getOriginal()

restore

public void restore(@NotNull
 @NotNull LexerPosition position)

Description copied from interface: Lexer

Restores the lexer to the specified state and position.

Parameters:

position - the state and position to restore to.

toString

public String toString()

Overrides:

toString in class Object

getCurrentPosition

@NotNull
public @NotNull LexerPosition getCurrentPosition()

Description copied from interface: Lexer

Returns the current position and state of the lexer.

Returns:

the lexer position and state.
