getDelegate

public final Lexer getDelegate()

start

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

从类复制的说明: 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.

指定者:

start 在类中 Lexer

参数:

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()

从类复制的说明: Lexer

Returns the current state of the lexer.

指定者:

getState 在类中 Lexer

返回:

the lexer state.

getTokenType

@Nullable
public @Nullable IElementType getTokenType()

从类复制的说明: Lexer

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

指定者:

getTokenType 在类中 Lexer

返回:

the current token.

getTokenStart

public int getTokenStart()

从类复制的说明: Lexer

Returns the start offset of the current token.

指定者:

getTokenStart 在类中 Lexer

返回:

the current token start offset.

getTokenEnd

public int getTokenEnd()

从类复制的说明: Lexer

Returns the end offset of the current token.

指定者:

getTokenEnd 在类中 Lexer

返回:

the current token end offset.

advance

public void advance()

从类复制的说明: Lexer

Advances the lexer to the next token.

指定者:

advance 在类中 Lexer

getBufferSequence

@NotNull
public final @NotNull CharSequence getBufferSequence()

从类复制的说明: 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.

指定者:

getBufferSequence 在类中 Lexer

返回:

the lexer buffer.

getBufferEnd

public int getBufferEnd()

从类复制的说明: 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.

指定者:

getBufferEnd 在类中 Lexer

返回:

the lexing end offset
