Method Detail

getMapping

public List<AStarGraphContainerMapSerializable> getMapping(String queryId,
                                                           String caseId)

getMapping.

Parameters:

queryId - a String object

caseId - a String object

Returns:

a List object

addDirtyCase

public void addDirtyCase(String queryID,
                         String caseID,
                         Similarity similarity)

Adds a case to the dirty matrix. This means that this similarity is not serialized to disk, yet. This method has to be synchronized!

Specified by:

addDirtyCase in class AbstractSimilarityCacheMatrix

Parameters:

queryID - the ID of the query

caseID - the ID of the case

similarity - the similarity object

removeCase

public void removeCase(String caseID)

Removes the case with the given ID from the similarity cache matrix.

Specified by:

removeCase in class AbstractSimilarityCacheMatrix

Parameters:

caseID - the ID of the case to remove

readCleanSimilarityCacheMatrix

public void readCleanSimilarityCacheMatrix(String path)

This method reads a similarity cache matrix from disk.

Specified by:

readCleanSimilarityCacheMatrix in class AbstractSimilarityCacheMatrix

Parameters:

path - the path to read from

writeDirtySimilarityCacheMatrix

public void writeDirtySimilarityCacheMatrix(String path)

This method writes out the dirty similarity cache to disk. In this process, the matrix is temporarily locked for further access and after the serialization, the similarities are copied to the clean matrix.

Specified by:

writeDirtySimilarityCacheMatrix in class AbstractSimilarityCacheMatrix

Parameters:

path - the path to write to
