Mutators

• public setData(newData:String, operator:Class<?>) : void
• public setProcessed(operator:Class<?>) : void

Accessors

• public getID() : String
• public getData() : String

...

• protected constructor(operationDate:Calendar, operatorClass:Class<?>, operationType:RecordMetaDataType, md5:String)
• protected constructor(operatorClass:Class<?>, operationType:RecordMetaDataType, md5:String)
  • simply creates cal:Calendar (based on now in GMT, with USA locale) and calls constructor(cal, operatorClass, operationType, md5)

Accessors

• public getDate() : Calendar
• public getOperator() : Class<?>
• public getOperation() : RecordMetaDataType
• public getMD5() : String

Utilities

• public static enum RecordMetaDataType
  • written
  • processed
  • error
• public static makeMD5Hash(text:String) : String
• public compareTo(RecordMetaData o) : int
  • for Comparable<RecordMetaData>
  • will allow sorting in reverse-chronological order

...

By extending Iterable, you will be able to do fun stuff like:

  RecordHandler recSet = new ExampleRecordHandler();

  for(Record rec : recSet){

    log.trace("

===============================================================");
    log.trace("Record "+rec.getID()+":");

    log.trace("---------------------------------------------------------------");

    log.trace(rec.getData());

  }

Map Record Handler

...

Stores records using Map<String,String> and metadata using Map<String,SortedSet<RecordMetaData>>

Constructors

Text File Record Handler

...

public class TextFileRecordHandler implements RecordHandler

Stores each record in location fileDir (resolved using apache commons vfs) with filename recID filled with recData. Allows for access to files located in (S)FTP, Local File System, HTTP(S), Temporary Files, Archive Files (Zip, Jar, Tartgz/tbz2, gzip, bzip2), res, ram, mime. Meta data for each record is stored in subdirectory fileDir/.metadata in individual files.

...

• protected constructor()
  • called by RecordHandler config parser... actually initialized by setParams(params)
• public constructor(fileDir:String)

JDBC Record Handler

...

class JDBCRecordHandler implements RecordHandler

Records are stored in a single, 3 column table:

...

• protected constructor()
  • called by RecordHandler config parser... actually initialized by setParams(params)
• public constructor(jdbcDriverClass:String, connLine:String, username:String, password:String, tableName:String, dataFieldName:String)panel
  connLine strings have the following format: "jdbc:%connType%://%host%:%port%/%dbName%"

  Panel
  new JDBCRecordHandler("com.mysql.jdbc.Driver", "jdbc:mysql://127.0.0.1:3306/dbName", "username", "password", "tableName", "dataFieldName");
