PartitionRecord

public PartitionRecord()

Method Detail

getWork

public int getWork()

add

public void add(SIROperator op,
                int k)

Add operator

op

with work amount

k

to this partition. Requires that this does not already contain

op

.

add

public void add(SIRContainer cont)

Add container

cont

to this. Requires that this does not already contain

cont

.

get

public SIROperator get(int i)

Returns the i'th contents of this

size

public int size()

Returns number of operators in this.

contains

public boolean contains(SIROperator op)

Returns whether or not this partition contains

pre

op.

asStringMap

public static HashMap<SIROperator,Object> asStringMap(LinkedList<PartitionRecord> partitions)

Given that

partitions

is a list of PartitionRecords, returns a hashmap in which each SIROperator that's in one of the partitions is mapped to a STRING representing the list of partitions it's assigned to.

asIntegerMap

public static HashMap<SIROperator,Integer> asIntegerMap(LinkedList<PartitionRecord> partitions)

Given that

partitions

is a list of PartitionRecords, returns a hashmap in which each SIROperator that's in one of the partitions is mapped to an Integer representing the list of partitions it's assigned to. Unlike asStringMap, requires that each operator is mapped to only one partition.
