Constructor Details

_JFlexLexer

public _JFlexLexer()

_JFlexLexer

public _JFlexLexer(Reader in)

Creates a new scanner

Parameters:

in - the java.io.Reader to read input from.

Method Details

getTokenStart

public final int getTokenStart()

Specified by:

getTokenStart in interface com.intellij.lexer.FlexLexer

getTokenEnd

public final int getTokenEnd()

Specified by:

getTokenEnd in interface com.intellij.lexer.FlexLexer

reset

public void reset(CharSequence buffer,
 int start,
 int end,
 int initialState)

Specified by:

reset in interface com.intellij.lexer.FlexLexer

yystate

public final int yystate()

Returns the current lexical state.

Specified by:

yystate in interface com.intellij.lexer.FlexLexer

yybegin

public final void yybegin(int newState)

Enters a new lexical state

Specified by:

yybegin in interface com.intellij.lexer.FlexLexer

Parameters:

newState - the new lexical state

yytext

public final CharSequence yytext()

Returns the text matched by the current regular expression.

yycharat

public final char yycharat(int pos)

Returns the character at position pos from the matched text. It is equivalent to yytext().charAt(pos), but faster

Parameters:

pos - the position of the character to fetch. A value from 0 to yylength()-1.

Returns:

the character at position pos

yylength

public final int yylength()

Returns the length of the matched text region.

yypushback

public void yypushback(int number)

Pushes the specified amount of characters back into the input stream. They will be read again by then next call of the scanning method

Parameters:

number - the number of characters to be read again. This number must not be greater than yylength()!

advance

public com.intellij.psi.tree.IElementType advance()
                                           throws IOException

Resumes scanning until the next regular expression is matched, the end of input is encountered or an I/O-Error occurs.

Specified by:

advance in interface com.intellij.lexer.FlexLexer

Returns:

the next token

Throws:

IOException - if any I/O-Error occurs
