DefaultJavaCommentLexer
Creates a new scanner- Parameters:
in
- the java.io.Reader to read input from.

-
Method Details
-
lex
- Specified by:
lex
in interfaceLexer
- Throws:
IOException
-
text
-
getLine
public int getLine() -
setLineOffset
public void setLineOffset(int lineOffset) -
getColumn
public int getColumn() -
setColumnOffset
public void setColumnOffset(int columnOffset) -
getCodeBody
- Specified by:
getCodeBody
in interfaceLexer
-
yyclose
Closes the input reader.- Throws:
IOException
- if the reader could not be closed.
-
yyreset
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
.Internal scan buffer is resized down to its initial length, if it has grown.
- Parameters:
reader
- The new input stream.
-
yyatEOF
public final boolean yyatEOF()Returns whether the scanner has reached the end of the reader it reads from.- Returns:
- whether the scanner has reached EOF.
-
yystate
public final int yystate()Returns the current lexical state.- Returns:
- the current lexical state.
-
yybegin
public final void yybegin(int newState) Enters a new lexical state.- Parameters:
newState
- the new lexical state
-
yytext
Returns the text matched by the current regular expression.- Returns:
- the matched text.
-
yycharat
public final char yycharat(int position) Returns the character at the given position from the matched text.It is equivalent to
yytext().charAt(pos)
, but faster.- Parameters:
position
- the position of the character to fetch. A value from 0 toyylength()-1
.- Returns:
- the character at
position
.
-
yylength
public final int yylength()How many characters were matched.- 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 thanyylength()
.
-
yylex
Resumes scanning until the next regular expression is matched, the end of input is encountered or an I/O-Error occurs.- Returns:
- the next token.
- Throws:
IOException
- if any I/O-Error occurs.
