Method Detail

main

public static void main(String[] args)

This test program demonstrates the use of the MarcPermissiveStreamReader to read Marc records, with the permissive setting turned on. It also demonstrates the capability of printing out the error messages that are generated when the MarcPermissiveStreamReader encounters records with structural error or encoding errors.

When run in verbose mode, (by passing -v as the first parameter) the program will display the entire record highlighting the lines in the record that have errors that the permissive reader was able to detect and make an attempt at correcting. Following that the program will list all of the errors that it found in the record.

When run in verbose mode as described above, the program is useful for validating records.

Shown below is the output generated when the program is run on the file error.mrc found in the resources sub-directory in the samples directory:

  Fatal Exception: error parsing data field for tag: 250 with data:    a1st ed.
  Typo         : Record terminator character not found at end of record length --- [ n/a : n/a ]
  Typo         : Record terminator appears after stated record length, reading extra bytes --- [ n/a : n/a ]
  Minor Error  : Field length found in record different from length stated in the directory. --- [ n/a : n/a ]

Normalizes strings to be able to show diffs.

Parameters:

out - The output diff stream

strNorm - The normalized string

strPerm - The perm string

dumpErrors

public static void dumpErrors(PrintStream out,
              ErrorHandler errorHandler)
