public ShortCentroidsResult()

Method Detail

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

asciiHeader

public String asciiHeader()

Description copied from interface: ReadableASCII

Header for ascii input. Will be automatically read by IOUtils when using readASCII().

Specified by:

asciiHeader in interface ReadableASCII

Specified by:

asciiHeader in interface WriteableASCII

Returns:

header

binaryHeader

public byte[] binaryHeader()

Description copied from interface: ReadableBinary

Header for binary input. Will be automatically read by IOUtils when using readBinary().

Specified by:

binaryHeader in interface ReadableBinary

Specified by:

binaryHeader in interface WriteableBinary

Returns:

header

readASCII

public void readASCII(Scanner br)
               throws IOException

Description copied from interface: ReadableASCII

Read internal state from in.

Specified by:

readASCII in interface ReadableASCII

Parameters:

br - source to read from.

Throws:

IOException - an error reading input

readBinary

public void readBinary(DataInput in)
                throws IOException

Description copied from interface: ReadableBinary

Read internal state from in.

Specified by:

readBinary in interface ReadableBinary

Parameters:

in - source to read from.

Throws:

IOException - an error reading input

writeASCII

public void writeASCII(PrintWriter writer)
                throws IOException

Description copied from interface: WriteableASCII

Write the content of this as ascii to out.

Specified by:

writeASCII in interface WriteableASCII

Parameters:

writer - sink to write to

Throws:

IOException - an error writing to out

writeBinary

public void writeBinary(DataOutput out)
                 throws IOException

Description copied from interface: WriteableBinary

Write the content of this as binary to out.

Specified by:

writeBinary in interface WriteableBinary

Parameters:

out - sink to write to

Throws:

IOException - an error writing to out

toString

public String toString()

Overrides:

toString in class Object

getCentroids

public short[][] getCentroids()

Specified by:

getCentroids in interface CentroidsProvider<short[]>

Returns:

the centroids generated by the clustering

defaultHardAssigner

public HardAssigner<short[],float[],IntFloatPair> defaultHardAssigner()

Description copied from interface: SpatialClusters

Get the default hard assigner for this clusterer. This method is potentially expensive, so callers should only call it once, and hold on to the result (and reuse it).

Specified by:

defaultHardAssigner in interface SpatialClusters<short[]>

Returns:

a hard assigner.

numDimensions

public int numDimensions()

Description copied from interface: SpatialClusters

Get the data dimensionality

Specified by:

numDimensions in interface SpatialClusters<short[]>

Returns:

the data dimensionality.

numClusters

public int numClusters()

Description copied from interface: SpatialClusters

Get the number of clusters.

Specified by:

numClusters in interface SpatialClusters<short[]>

Returns:

number of clusters.
