Method Detail

addStatement

public void addStatement(String subject,
                         String predicate,
                         String object,
                         double similarity)

Description copied from interface: ISerializer

Adds a triple to the buffer of the serializer. Requires the method open to have been carried out

Specified by:

addStatement in interface ISerializer

Overrides:

addStatement in class NtSerializer

Parameters:

subject - The subject of the triple

predicate - The predicate of the triple

object - The object of the triple

similarity - value

printStatement

public void printStatement(String subject,
                           String predicate,
                           String object,
                           double similarity)

Description copied from class: NtSerializer

Writes in the file statement by statement. Rather slow, not to be used

Specified by:

printStatement in interface ISerializer

Overrides:

printStatement in class NtSerializer

Parameters:

subject - Source object of a mapping, subject of the triple to be written

predicate - Predicate to be written

object - Target object of a mapping, object of the triple to be written

similarity - Similarity achieved by the subject and object

getName

public String getName()

Specified by:

getName in interface ISerializer

Overrides:

getName in class NtSerializer

Returns:

name

writeToFile

public void writeToFile(AMapping mapping,
                        String predicate,
                        String file)

Gets a mapping and serializes it to a file in the N3 format. The method assume that the class already knows all the prefixes used in the uris and expands those.

Specified by:

writeToFile in interface ISerializer

Overrides:

writeToFile in class NtSerializer

Parameters:

mapping - Mapping to serialize

predicate - Predicate to use while serializing

file - File in which the mapping is to be serialized

getFileExtension

public String getFileExtension()

Specified by:

getFileExtension in interface ISerializer

Overrides:

getFileExtension in class NtSerializer

Returns:

file extension

getSeperator

public String getSeperator()

Returns:

the CSV file separator

setSeperator

public void setSeperator(String seperator)

Parameters:

seperator - to be set
