Method Detail

getLabel

java.lang.String getLabel()

Gets the name of this field.

Returns:

String The name of this field.

getPath

com.orchestranetworks.schema.Path getPath()

Gets the absolute path of this field in the data model.

Returns:

Path The absolute path of this field in the data model.

getComparisonAlgorithm

FieldComparisonAlgorithm getComparisonAlgorithm()

Gets the algorithm used to compute a score.

Returns:

FieldComparisonAlgorithm The algorithm used to compute a score of two fields in two different records.

getComparisonParameters

java.util.Collection<ParameterValue> getComparisonParameters()

Gets all parameters used to execute a comparison algorithm.

If the comparison function used in the decision node is DecisionNodeComparisonType.ALL_FIELD_MATCH or DecisionNodeComparisonType.AT_LEAST_N_FIELD_MATCH, all decision fields in this node use a parameter named minimumScore and some specific parameters are used for certain field comparison algorithms:

• FieldComparisonAlgorithm.EXACT uses a parameter named caseSensitive
• FieldComparisonAlgorithm.FUZZY_FULL_TEXT uses a parameter named maxDistance
• FieldComparisonAlgorithm.RANGE uses two parameters named rangeValue and rangeUnit
• FieldComparisonAlgorithm.PREDICATE uses a parameter named predicate

If the comparison function used in the decision node is DecisionNodeComparisonType.AVERAGE, all decision fields in this node use a parameter named weight

Returns:

Collection All parameters used to execute a comparison algorithm.

isMatchWhenBothValuesAreNull

java.lang.Boolean isMatchWhenBothValuesAreNull()

Returns:

true if the add-on identifies two matched fields where both field values are null.

isMatchWhenOneValueIsNull

java.lang.Boolean isMatchWhenOneValueIsNull()

Returns:

true if the add-on identifies two matched fields where only one field value is null.

getScore

java.lang.Double getScore()

Gets the computed score.

Returns:

Double The score computed when comparing two fields in two different records.

For example:

• If the Exact algorithm is used, the score will be 0.0 or 1.0.
• If the Levenshtein algorithm is used, the score will be in the range of 0.0 to 1.0.
