Constructor Detail

PartialResult

public PartialResult()

Default constructor (necessary for the ExternalizableLite interface).

PartialResult

public PartialResult(PartitionSet partMask)

Construct a PartialResult.

Parameters:

partMask - the partitions to be included in creating this partial result

PartialResult

public PartialResult(QueryContext ctx,
                     PartitionSet partMask)

Construct a PartialResult.

Parameters:

ctx - the query context

partMask - the partitions to be included in creating this partial result

PartialResult

public PartialResult(QueryRecord.PartialResult result)

Copy constructor for a Result.

Parameters:

result - the result to copy

Method Detail

getSteps

public List<? extends QueryRecord.PartialResult.Step> getSteps()

Get the list of steps for this query record partial result in the order that they occurred.

Specified by:

getSteps in interface QueryRecord.PartialResult

Returns:

the list of steps

getPartitions

public PartitionSet getPartitions()

Get the set of partitions associated with this partial result.

Specified by:

getPartitions in interface QueryRecord.PartialResult

Returns:

the partition set

instantiateExplainStep

public QueryRecord.PartialResult.ExplainStep instantiateExplainStep(Filter filter)

Instantiate a new explain step for the given filter and add it to this result's list of steps. This method is called on the server for the top level filter.

Parameters:

filter - the filter

Returns:

the new explain step

instantiateTraceStep

public QueryRecord.PartialResult.TraceStep instantiateTraceStep(Filter filter)

Instantiate a new trace step for the given filter and add it to this result's list of steps. This method is called on the server for the top level filter(s).

Parameters:

filter - the filter

Returns:

the new trace step

merge

protected void merge(QueryRecord.PartialResult result)

Merge the given result with this one.

Parameters:

result - the result to merge

isMatching

protected boolean isMatching(QueryRecord.PartialResult result)

Determine whether or not the given result is capable of being placed in one-to-one correspondence with this result. Results are matching if their owned lists of steps have the same size, and all pairs of steps in the two lists are matching.

Parameters:

result - the result to be checked

Returns:

true iff the given result matches with this result

readExternal

public void readExternal(DataInput in)
                  throws IOException

Restore the contents of this object by loading the object's state from the passed DataInput object.

Specified by:

readExternal in interface ExternalizableLite

Parameters:

in - the DataInput stream to read data from in order to restore the state of this object

Throws:

IOException - if an I/O exception occurs

NotActiveException - if the object is not in its initial state, and therefore cannot be deserialized into

writeExternal

public void writeExternal(DataOutput out)
                   throws IOException

Save the contents of this object by storing the object's state into the passed DataOutput object.

Specified by:

writeExternal in interface ExternalizableLite

Parameters:

out - the DataOutput stream to write the state of this object to

Throws:

IOException - if an I/O exception occurs

readExternal

public void readExternal(PofReader in)
                  throws IOException

Restore the contents of a user type instance by reading its state using the specified PofReader object.

Specified by:

readExternal in interface PortableObject

Parameters:

in - the PofReader from which to read the object's state

Throws:

IOException - if an I/O error occurs

writeExternal

public void writeExternal(PofWriter out)
                   throws IOException

Save the contents of a POF user type instance by writing its state using the specified PofWriter object.

Specified by:

writeExternal in interface PortableObject

Parameters:

out - the PofWriter to which to write the object's state

Throws:

IOException - if an I/O error occurs
