public SMStringNGramImpl()

Method Details

compute

public Similarity compute(DataObject queryObject,
 DataObject caseObject,
 SimilarityValuator valuator)

Specified by:

compute in interface SimilarityMeasure

Returns:

getN

public int getN()

Description copied from interface: SMStringNGram

Gets the value of n-

Specified by:

getN in interface SMStringNGram

Returns:

The value of n as integer

setN

public void setN(int n)

Description copied from interface: SMStringNGram

Sets the value for n.

Specified by:

setN in interface SMStringNGram

Parameters:

n - The required value for n

isCaseInsensitive

public boolean isCaseInsensitive()

Description copied from interface: SMStringNGram

Gets boolean value, whether case is insensitive.

Specified by:

isCaseInsensitive in interface SMStringNGram

Returns:

True, if case is insensitive

isCaseSensitive

public boolean isCaseSensitive()

Description copied from interface: SMStringNGram

Gets boolean value, whether case is sensitive.

Specified by:

isCaseSensitive in interface SMStringNGram

Returns:

True, if case is sensitive

setCaseInsensitive

public void setCaseInsensitive()

Description copied from interface: SMStringNGram

Sets case to insensitive.

Specified by:

setCaseInsensitive in interface SMStringNGram

setCaseSensitive

public void setCaseSensitive()

Description copied from interface: SMStringNGram

Sets case to sensitive.

Specified by:

setCaseSensitive in interface SMStringNGram

getSystemName

public String getSystemName()

Description copied from interface: SimilarityMeasure

The system name can be used to distinguish the similarity measures. Each similarity measure that can be instantiated contains a static final field called NAME representing the system name, e.g., SMAggregateEuclidian.NAME

The system name must also be given during initialization, see SimilarityModel.createSimilarityMeasure(String, DataClass).

Specified by:

getSystemName in interface SimilarityMeasure

Returns:

The system name of the similarity measure. This is equal to SimilarityMeasure.NAME.
