WARCRecord
public class WARCRecord extends ArchiveRecord implements WARCConstants(Code)
A WARC file Record.
author:
   stack



Constructor Summary
public  WARCRecord(InputStream in, String identifier, long offset)
     Constructor.
public  WARCRecord(InputStream in, ArchiveRecordHeader headers)
     Constructor.
public  WARCRecord(InputStream in, String identifier, long offset, boolean digest, boolean strict)
     Constructor.
Parameters:
  in - Stream cue'd up to be at the start of the record this instanceis to represent or, if headers is not null, just past theHeader Line and Named Fields.
Parameters:
  identifier - Identifier for this the hosting Reader.
Parameters:
  offset - Current offset into in (Used to keepposition properly aligned).

Method Summary
protected  StringgetMimetype4Cdx(ArchiveRecordHeader h)
    
public static  booleanisCR(char c)
    
public static  booleanisCROrLF(char c)
    
public static  booleanisLF(char c)

protected  ArchiveRecordHeaderparseHeaders(InputStream in, String identifier, long offset, boolean strict)
     Parse WARC Header Line and Named Fields.
Parameters:
  in - Stream to read.
Parameters:
  identifier - Identifier for the hosting Reader.
Parameters:
  offset - Absolute offset into Reader.
Parameters:
  strict - Whether to be loose parsing or not.
protected  voidparseNamedFields(InputStream in, Map<Object, Object> fields)
    
protected  byte[]readLine(InputStream in, boolean strict)
     Read a line. A 'line' in this context ends in CRLF and contains ascii-only and no control-characters.
Parameters:
  in - InputStream to read.
Parameters:
  strict - Strict parsing (If false, we'll eat whitespace before therecord.


Constructor Detail

public WARCRecord(InputStream in, String identifier, long offset) throws IOException(Code)
Constructor.
Parameters:
  in - Stream cue'd up to be at the start of the record this instanceis to represent.
throws:
  IOException -

WARCRecord
public WARCRecord(InputStream in, String identifier, long offset, boolean digest, boolean strict) throws IOException(Code)
Constructor.
Parameters:
  in - Stream cue'd up to be at the start of the record this instanceis to represent or, if headers is not null, just past theHeader Line and Named Fields.
Parameters:
  identifier - Identifier for this the hosting Reader.
Parameters:
  offset - Current offset into in (Used to keepposition properly aligned). Usually 0.
Parameters:
  digest - True if we're to calculate digest for this record. Notdigesting saves about ~15% of cpu during parse.
Parameters:
  strict - Be strict parsing (Parsing stops if file inproperlyformatted).
throws:
  IOException -
