|
The CsvIterator class allows CSV sources to be iterated on a record basis. The source of the input data is either a AbstractLineIterator object or an InputStream object. More...

Public Member Functions | |
| constructor (Qore::AbstractLineIterator li, *hash opts) | |
| Creates the CsvIterator in single-type mode with general line iterator to read and an option hash. More... | |
| constructor (Qore::AbstractLineIterator li, hash spec, hash opts) | |
| Creates the CsvIterator in multi-type mode with general line iterator to read and optionally an option hash. More... | |
| constructor (Qore::InputStream input, string encoding="UTF-8", *hash opts) | |
| Creates the CsvIterator from an InputStream, the input encoding, and optionally an option hash. More... | |
| constructor (Qore::InputStream input, string encoding="UTF-8", hash spec, hash opts) | |
| Creates the CsvIterator in multi-type mode from an InputStream, the record specification, the input encoding, and optionally an option hash. More... | |

| *list | getHeaders () |
| Returns the current record headers or NOTHING if no headers have been detected or saved yet. More... | |
| *list | getHeaders (string type) |
| Returns a list of headers for the given record or NOTHING if the record is not recognized. More... | |

| string | identifyType (list rec) |
| Identify a fixed-length line type using identifyTypeImpl(); may be overridden if necessary. More... | |
| int | index () |
| Returns the row index being iterated, which does not necessarily correspond to the line number when there are header rows and blank lines are skipped. More... | |
| int | lineNumber () |
| Returns the current iterator line number in the file (the first line is line 1) or 0 if not pointing at a valid element. More... | |
