Method Detail

createQueryForSingleValue

public QueryFactoryResult createQueryForSingleValue(String fieldName,
                                                    Operator operator,
                                                    List<QueryLiteral> rawValues)

Description copied from interface: OperatorSpecificQueryFactory

Generates the Query for a single operand id.

Specified by:

createQueryForSingleValue in interface OperatorSpecificQueryFactory

Parameters:

fieldName - the index field name the query should be generated for.

operator - operator which is handled by this implementation.

rawValues - the raw values provided to the operand that need to be converted to index values.

Returns:

the queryFactoryResult that contains the query and the metadata.

createResult

public QueryFactoryResult createResult(String fieldName,
                                       List<QueryLiteral> rawValues,
                                       Operator operator,
                                       boolean handleEmpty)

getQueries

protected List<org.apache.lucene.search.Query> getQueries(String fieldName,
                                                          List<QueryLiteral> rawValues)

createQueryForEmptyOperand

public QueryFactoryResult createQueryForEmptyOperand(String fieldName,
                                                     Operator operator)

Description copied from interface: OperatorSpecificQueryFactory

Generates the query for an operand that has an OperandHandler that returns true for the isEmpty method. This should generate a Lucene query that will perform the correct search for issues where the field value is not set.

Specified by:

createQueryForEmptyOperand in interface OperatorSpecificQueryFactory

Parameters:

fieldName - the index field name the query should be generated for.

operator - operator which is handled by this implementation.

Returns:

the queryFactoryResult that contains the query and the metadata.

createQueryForMultipleValues

public QueryFactoryResult createQueryForMultipleValues(String fieldName,
                                                       Operator operator,
                                                       List<QueryLiteral> rawValues)

Description copied from interface: OperatorSpecificQueryFactory

Generates the Query for a list of operand ids.

Specified by:

createQueryForMultipleValues in interface OperatorSpecificQueryFactory

Parameters:

fieldName - the index field name the query should be generated for.

operator - operator which is handled by this implementation.

rawValues - the raw values provided to the operand that need to be converted to index values.

Returns:

the queryFactoryResult that contains the query and the metadata.

handlesOperator

public boolean handlesOperator(Operator operator)

Specified by:

handlesOperator in interface OperatorSpecificQueryFactory

Parameters:

operator - the operator in question.

Returns:

true if this implementation can handle the operator, false otherwise.
