public MIFStringTokenizer()

Builds a tokenizer

Method Detail

readLine

public boolean readLine(java.lang.String line)

"Reads" a line from the given line, and initializes the token.

Parameters:

line -

Returns:

true if could read a non empty line (i.e. line != "")

readLine

public boolean readLine()

Tries to read a line from the input buffer (if any) and store it in the line buffer

Returns:

True if a non-null string was read

getToken

public java.lang.String getToken(char separator,
                                 boolean nextLineIfEmpty,
                                 boolean quotedStrings)
                          throws com.vividsolutions.jts.io.ParseException

Cuts the first token from line buffer using the given separator, taking in to account string delimiters if needed
Strings might be delimited by double quotes. Escaping char is a double quote, i.e. "\"" becomes """".

Parameters:

separator - Character used as token separator.

nextLineIfEmpty - If the returned token is empty, try to read it from the next line.

quotedStrings - If true, expects a quoted string and read it, otherwise treats the double quotes as a normal char.

Returns:

The parsed token

Throws:

com.vividsolutions.jts.io.ParseException - DOCUMENT ME!

getToken

protected java.lang.String getToken(char separator,
                                    boolean nextLineIfEmpty)
                             throws com.vividsolutions.jts.io.ParseException

DOCUMENT ME!

Parameters:

separator - DOCUMENT ME!

nextLineIfEmpty - DOCUMENT ME!

Returns:

DOCUMENT ME!

Throws:

com.vividsolutions.jts.io.ParseException - DOCUMENT ME!

getToken

protected java.lang.String getToken(char separator)
                             throws com.vividsolutions.jts.io.ParseException

DOCUMENT ME!

Parameters:

separator - DOCUMENT ME!

Returns:

DOCUMENT ME!

Returns:

DOCUMENT ME!

Throws:

com.vividsolutions.jts.io.ParseException - DOCUMENT ME!
