Class SerializedRecord

    java.lang.Object
      org.apache.hadoop.contrib.failmon.SerializedRecord

    public class SerializedRecord

extends Object

Objects of this class hold the serialized representations of EventRecords. A SerializedRecord is essentially an EventRecord with all its property values converted to strings. It also provides some convenience methods for printing the property fields in a more readable way.

Constructor Summary
`SerializedRecord(EventRecord source)` Create the SerializedRecord given an EventRecord.

Method Summary
`static void` | `arrangeKeys(ArrayList<String> keys)` Arrange the keys to provide a more readable printing order: first goes the timestamp, then the hostname and then the type, followed by all other keys found.
`String` | `get(String fieldName)` Get the value of a property of the EventRecord.
`boolean` | `isValid()` Check if the SerializedRecord is a valid one, i.e., whether it represents meaningful metric values.
`void` | `set(String fieldName, String fieldValue)` Set the value of a property of the EventRecord.
`String` | `toString()` Creates and returns a string reperssentation of the object

### SerializedRecord

    public SerializedRecord(EventRecord source)

  Create the SerializedRecord given an EventRecord.

### set

    public void set(String fieldName,
                    String fieldValue)

  Set the value of a property of the EventRecord.

  Arrange the keys to provide a more readable printing order: first goes the timestamp, then the hostname and then the type, followed by all other keys found.

  Parameters:
    `keys` - The input ArrayList of keys to re-arrange.

### isValid

    public boolean isValid()

  Check if the SerializedRecord is a valid one, i.e., whether it represents meaningful metric values.

  Returns:
    true if the EventRecord is a valid one, false otherwise.

### toString
