Parameters:

type - is the type of string requested.

type	return value
BEGIN_MATRIX	Tag for the beginning of the matrix.
END_MATRIX	Tag for the end of the matrix.
BEGIN_COLUMN_LABELS	Tag for the beginning of the column labels row.

ENTRY	The row-col entry of the matrix

entry - is the entry to be formatted. This is only used if type equals ENTRY. For other values of type, this can be set to null.

row - is the (0-based) row number of the element to be formatted. This is -1 if there is no row number associated with this request.

col - is the (0-based) column number of the element to be formatted. This is -1 if there is no column number associated with this request.

pos - is a ParsePosition object used to indicate the alignment center of the return string. This is used only if type==ENTRY. If the entry is a double then the index is the position of the decimal point. If the entry is an int then the index is the position of the end of the formatted integer.

Returns:
