init

public void init(int index)

Specified by:

init in interface objects.ConfigurableObject

getIndex

public int getIndex()

Specified by:

getIndex in interface objects.ConfigurableObject

validate

public void validate(int index)

Specified by:

validate in interface objects.ConfigurableObject

getTimestamp

public long getTimestamp()

Description copied from interface: TimestampedObject

Returns the object creation timestamp encoded in the object.

Specified by:

getTimestamp in interface TimestampedObject

resetTimestamp

public void resetTimestamp()

Description copied from interface: TimestampedObject

Resets the timestamp encoded in the object to the current time.

resetTimestamp in interface TimestampedObject

toString

public String toString()

Overrides:

toString in class Object

equals

public boolean equals(Object o)

Two Messages are considered to be equal if they have the same content (index) and timestamp. This provides stronger validation than the validate(int) method that only considers the index.

Overrides:

equals in class Object
