public interface CSVParse (Code)
Read files in comma separated value format. More information about this class is available from ostermiller.org. This interface is designed to be set of general methods that all CSV parsers should implement.

Method Summary
public void changeDelimiter(char newDelim)
     Change this parser so that it uses a new delimiter.
public void changeQuote(char newQuote)
     Change this parser so that it uses a new character for quoting.
public void close()
     Close any stream upon which this parser is based.
public String[][] getAllValues()
     Get all the values from the file.
If the file has already been partially read, only the values that have not already been read will be included.
Each line of the file that has at least one value will be represented.
public int getLastLineNumber()
     Get the line number that the last token came from.
public String[] getLine()
     Get all the values from a line.
public int lastLineNumber()
     Get the line number that the last token came from.
public String nextValue()
     Read the next value from the file.

Method Detail
changeDelimiter
public void changeDelimiter(char newDelim) throws BadDelimiterException(Code)
Change this parser so that it uses a new delimiter.
The initial character is a comma, the delimiter cannot be changed to a quote or other character that has special meaning in CSV.
Parameters:
  newDelim - delimiter to which to switch.
throws:
  BadDelimiterException - if the character cannot be used as a delimiter.

changeQuote
public void changeQuote(char newQuote) throws BadQuoteException(Code)
Change this parser so that it uses a new character for quoting.
The initial character is a double quote ("), the delimiter cannot be changed to a comma or other character that has special meaning in CSV.
Parameters:
  newQuote - character to use for quoting.
throws:
  BadQuoteException - if the character cannot be used as a quote.

close
public void close() throws IOException(Code)
Close any stream upon which this parser is based.
since:
   ostermillerutils 1.02.26
throws:
  IOException - if an error occurs while closing the stream.

getAllValues
public String[][] getAllValues() throws IOException(Code)
Get all the values from the file.
If the file has already been partially read, only the values that have not already been read will be included.
Each line of the file that has at least one value will be represented. Comments and empty lines are ignored.
The resulting double array may be jagged. all the values from the file or null if there are no more values.
throws:
  IOException - if an error occurs while reading.
since:
   ostermillerutils 1.00.00

getLastLineNumber
public int getLastLineNumber()(Code)
Get the line number that the last token came from.
New line breaks that occur in the middle of a token are not counted in the line number count. line number or -1 if no tokens have been returned yet.
since:
   ostermillerutils 1.00.00

getLine
public String[] getLine() throws IOException(Code)
Get all the values from a line.
If the line has already been partially read, only the values that have not already been read will be included. all the values from the line or null if there are no more values.
throws:
  IOException - if an error occurs while reading.
since:
   ostermillerutils 1.00.00

lastLineNumber
public int lastLineNumber()(Code)
Get the line number that the last token came from. line number or -1 if no tokens have been returned yet.
since:
   ostermillerutils 1.00.00

nextValue
public String nextValue() throws IOException(Code)
Read the next value from the file. The line number from which this value was taken can be obtained from getLastLineNumber(). the next value or null if there are no more values.
throws:
  IOException - if an error occurs while reading.
since:
   ostermillerutils 1.00.00
