Constructor Detail

PropertiesLexer

public PropertiesLexer()

Create an empty lexer, yyrset will be called later to reset and assign the reader

PropertiesLexer

public PropertiesLexer(java.io.Reader in)

Creates a new scanner There is also a java.io.InputStream version of this constructor.

Parameters:

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

PropertiesLexer

public PropertiesLexer(java.io.InputStream in)

Creates a new scanner. There is also java.io.Reader version of this constructor.

Parameters:

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

Method Detail

yychar

public int yychar()

Description copied from class: DefaultJFlexLexer

Return the char number from beginning of input stream. This is NOT implemented by JFlex, so the code must be added to create this and return the private yychar field

Specified by:

yychar in class DefaultJFlexLexer

yyclose

public final void yyclose()
                   throws java.io.IOException

Closes the input stream.

Throws:

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.

Specified by:

yyreset in class DefaultJFlexLexer

Parameters:

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

Parameters:

newState - the new lexical state

yytext

public final java.lang.String yytext()

Returns the text matched by the current regular expression.

Specified by:

yytext in class DefaultJFlexLexer

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

Specified by:

yycharat in class DefaultJFlexLexer

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.

Specified by:

yylength in class DefaultJFlexLexer

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()!

yylex

public Token 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.

Specified by:

yylex in class DefaultJFlexLexer

Returns:

the next token

Throws:

java.io.IOException - if any I/O-Error occurs
