Constructor Detail

SequencePlotPointComparator

public SequencePlotPointComparator()

The default constructor uses comparison by XandY in ascending manner and not meta-data key.

SequencePlotPointComparator

public SequencePlotPointComparator(XYSequencePointComparator.Comparison comp,
                                   boolean ascending,
                                   String metaDataKey)

This constructor initializes the comparator either with comparison by X or by Y or both. Either in ascending manner or descending.

Parameters:

comp - the type of comparison

ascending - if true then the ordering is done in ascending manner, otherwise descending

Method Detail

getMetaDataKey

public String getMetaDataKey()

Returns the meta-data key to use for the comparison.

Returns:

the key, null if not used

getMetaData

protected Object getMetaData(SequencePlotPoint p)

Returns the associated meta-data value.

Parameters:

p - the point to obtain the meta-data from

Returns:

the value, null if not available

compare

public int compare(DataPoint o1,
                   DataPoint o2)

Compares its two arguments for order. Returns a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second.

Overrides:

compare in class XYSequencePointComparator<X extends Number & Comparable,Y extends Number & Comparable>

Parameters:

o1 - the first object

o2 - the second object

Returns:

a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second.
