Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

getNumberOfRegions

public int getNumberOfRegions()

Returns:

the numberOfRegions

getNumberOfRequests

public int getNumberOfRequests()

Returns:

the numberOfRequests

Parameters:

in - DataInput to deseriablize this object from.

Throws:

IOException

write

public void write(DataOutput out)
           throws IOException

Serialize the fields of this object to out.

Specified by:

write in interface Writable

Parameters:

out - DataOuput to serialize this object into.

Throws:

IOException

compareTo

public int compareTo(Object o)

Specified by:

compareTo in interface Comparable
