メソッドの詳細

advance

public boolean advance()
                throws java.io.IOException
move on to next token.

定義:
インタフェース Parser.yyInput 内の advance
戻り値:
false if positioned beyond tokens.
例外:
IOException - on input error.

token

public int token()
classifies current token. Should not be called if advance() returned false.

定義:
インタフェース Parser.yyInput 内の token
戻り値:
current %token or single character.

dp

protected void dp(java.lang.String msg)

value

public java.lang.Object value()
associated with current token. Should not be called if advance() returned false.

定義:
インタフェース Parser.yyInput 内の value
戻り値:
value for token().

yyclose

public final void yyclose()
                   throws java.io.IOException
Closes the input stream.

java.io.IOException

yyreset

public final void yyreset(java.io.Reader reader)
Resets the scanner to read from a new input stream. Does not close the old reader. All internal variables are reset, the old input stream cannot be reused (internal buffer is discarded and lost). Lexical state is set to ZZ_INITIAL.

パラメータ:
reader - the new input stream

yystate

public final int yystate()
Returns the current lexical state.


yybegin

public final void yybegin(int newState)
Enters a new lexical state

パラメータ:
newState - the new lexical state

yytext

public final java.lang.String 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

パラメータ:
pos - the position of the character to fetch. A value from 0 to yylength()-1.
戻り値:
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

パラメータ:
number - the number of characters to be read again. This number must not be greater than yylength()!

yylex

public int yylex()
          throws java.io.IOException
Resumes scanning until the next regular expression is matched, the end of input is encountered or an I/O-Error occurs.

戻り値:
the next token
例外:
java.io.IOException - if any I/O-Error occurs
