Creates the DocumentTableInputStreamLineIterator for iterating over the given InputStream
- Parameters
-
is | the InputStream to iterate over |
encoding | character encoding of the data from input stream; if not ASCII-compatible, all data will be converted to UTF-8; if not present, the default character encoding is assumed |
eol | the optional end of line character(s) to use to detect lines in the data; if this string is not passed, then the end of line character(s) are detected automatically, and can be either "\n" , "\r" , or "\r\n" |
do_trim | if True the string return values for the lines iterated will be trimmed of the eol bytes |
- Exceptions
-
ENCODING-CONVERSION-ERROR | this exception could be thrown if the eol argument has a different character encoding from the data's and an error occurs during encoding conversion |
- Note
- table cell docs may span multiple lines as long as the lines end in a
"\"
character
◆ getLine()
string Qdx::DocumentTableInputStreamLineIterator::getLine |
( |
| ) |
|
Returns the current line in the data or throws an ITERATOR-ERROR
exception if the iterator is invalid.
- Example:
map printf("+ %y\n", i.getLine()), i;
- Returns
- the current line in the data or throws an
ITERATOR-ERROR
exception if the iterator is invalid
- Exceptions
-
ITERATOR-ERROR | the iterator is not pointing at a valid element |
ITERATOR-THREAD-ERROR | this exception is thrown if this method is called from any thread other than the thread that created the object |
LINE-CONTINUATION-ERROR | thrown if the last line ends in a line continuation character ("\")
@see getValue()
@note table cell docs may span multiple lines as long as the lines end in a \c "" character |
◆ getValue()
string Qdx::DocumentTableInputStreamLineIterator::getValue |
( |
| ) |
|
Returns the current line in the data or throws an ITERATOR-ERROR
exception if the iterator is invalid.
- Example:
map printf("+ %y\n", i.getValue()), i;
- Returns
- the current line in the data or throws an
ITERATOR-ERROR
exception if the iterator is invalid
- Exceptions
-
ITERATOR-ERROR | the iterator is not pointing at a valid element |
ITERATOR-THREAD-ERROR | this exception is thrown if this method is called from any thread other than the thread that created the object |
LINE-CONTINUATION-ERROR | thrown if the last line ends in a line continuation character ("\")
