## org.apache.commons.net.ftp
Class FTPFileEntryParserImpl

    java.lang.Object
      org.apache.commons.net.ftp.FTPFileEntryParserImpl

All Implemented Interfaces:
  FTPFileEntryParser

Direct Known Subclasses:
  CompositeFileEntryParser, RegexFTPFileEntryParserImpl

    public abstract class FTPFileEntryParserImpl

extends Object
implements FTPFileEntryParser

This abstract class implements both the older FTPFileListParser and newer FTPFileEntryParser interfaces with default functionality. All the classes in the parser subpackage inherit from this.

Constructor Summary
`FTPFileEntryParserImpl()` The constructor for a FTPFileEntryParserImpl object.

Method Summary
`List<String>` | `preParse(List<String> original)` This method is a hook for those implementors (such as VMSVersioningFTPEntryParser, and possibly others) which need to perform some action upon the FTPFileList after it has been created from the server stream, but before any clients see the list.
`String` | `readNextEntry(BufferedReader reader)` Reads the next entry using the supplied BufferedReader object up to whatever delemits one entry from the next.

Methods inherited from class java.lang.Object
`clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait`

Methods inherited from interface org.apache.commons.net.ftp.FTPFileEntryParser

Constructor Detail

### FTPFileEntryParserImpl

    public FTPFileEntryParserImpl()

  The constructor for a FTPFileEntryParserImpl object.

Method Detail

### readNextEntry

    public String readNextEntry(BufferedReader reader)
                         throws IOException

  Reads the next entry using the supplied BufferedReader object up to whatever delemits one entry from the next. This default implementation simply calls BufferedReader.readLine().

  Specified by:
    `readNextEntry` in interface `FTPFileEntryParser`
  Parameters:
    `reader` - The BufferedReader object from which entries are to be read.
  Returns:
    A string representing the next ftp entry or null if none found.
  Throws:
    `IOException` - thrown on any IO Error reading from the reader.

### preParse

    public List<String> preParse(List<String> original)

  This method is a hook for those implementors (such as VMSVersioningFTPEntryParser, and possibly others) which need to perform some action upon the FTPFileList after it has been created from the server stream, but before any clients see the list. This default implementation removes entries that do not parse as files.

  Specified by:
    `preParse` in interface `FTPFileEntryParser`
  Parameters:
    `original` - Original list after it has been created from the server stream
  Returns:
    `original` unmodified.
