EditClassCount

public EditClassCount(EditClassCatalogue editClasses)

Create a new empty count that reports occurrences of the given edit class.

Parameters:

editClasses - edit classes whose occurrences should be counted.

Method Details

ISEMIGROUP

public static org.variantsync.functjonal.category.InplaceSemigroup<EditClassCount> ISEMIGROUP()

Composes two edit class counts by composing their respective occurrence counts for each edit class.

• ISEMIGROUP()

reportOccurrenceFor

public void reportOccurrenceFor(EditClass editClass,
 CommitDiff commit)

Report the match of the given edit class in the given commit diff. The count of the given edit class will be incremented and the commit will be memorized as one of the commits in which this edit class was matched.

Parameters:

editClass - The edit class that was matched.

commit - The CommitDiff in which the edit class match occurred.

Throws:

AssertionError - when the given edit class is not present this counts catalog.

• EditClassCount(EditClassCatalogue)

parse

public static EditClassCount parse(List<String> lines,
 String uuid)

Parses lines containing edit classes to EditClassCount.

Parameters:

lines - Lines containing edit classes to be parsed

Returns:

EditClassCount

snapshot

public LinkedHashMap<String,String> snapshot()

Description copied from interface: Metadata

Create a key-value store of the metadata that can be used for serialization.

Specified by:

snapshot in interface Metadata<EditClassCount>

Returns:

A LinkedHashMap that stores all relevant properties to export. The return type has to be a LinkedHashMap to obtain insertion-order iteration.

setFromSnapshot

public void setFromSnapshot(LinkedHashMap<String,String> snap)

Specified by:

setFromSnapshot in interface Metadata<EditClassCount>

semigroup

public org.variantsync.functjonal.category.InplaceSemigroup<EditClassCount> semigroup()

Mutates and returns first element.

Specified by:

semigroup in interface Metadata<EditClassCount>

getOccurrences

public LinkedHashMap<EditClass,EditClassCount.Occurrences> getOccurrences()

Returns the current occurrence count for each considered edit class.
