Class ActualValueEqualityQueryFactory

java.lang.Object
  com.atlassian.jira.jql.query.ActualValueEqualityQueryFactory

All Implemented Interfaces:

OperatorSpecificQueryFactory

public class ActualValueEqualityQueryFactory
extends Object
implements OperatorSpecificQueryFactory

Creates equality queries for clauses whose value is exactly the same as the indexed value(e.g. votes and duration).

Since:

v4.0

Constructor Summary

ActualValueEqualityQueryFactory(IndexValueConverter indexValueConverter)
Creates a Query Factory that does not have a specified representation of empty values and instead checks for the field value absence.

ActualValueEqualityQueryFactory(IndexValueConverter indexValueConverter, String emptyIndexValue)
Creates a Query Factory that represents Empty values with emptyIndexValue

Method Summary

QueryFactoryResult	createQueryForEmptyOperand(String fieldName, Operator operator) Generates the query for an operand that has an OperandHandler that returns true for the isEmpty method.
QueryFactoryResult	createQueryForMultipleValues(String fieldName, Operator operator, List<QueryLiteral> rawValues) Generates the Query for a list of operand ids.
QueryFactoryResult	createQueryForSingleValue(String fieldName, Operator operator, List<QueryLiteral> rawValues) Generates the Query for a single operand id.
boolean	handlesOperator(Operator operator)

Constructor Detail

ActualValueEqualityQueryFactory

public ActualValueEqualityQueryFactory(IndexValueConverter indexValueConverter,
                                       String emptyIndexValue)

Creates a Query Factory that represents Empty values with emptyIndexValue

Parameters:

indexValueConverter - used for converting query literals to the index representation

emptyIndexValue - the value that is used to represent empty values in the index

ActualValueEqualityQueryFactory

public ActualValueEqualityQueryFactory(IndexValueConverter indexValueConverter)

Creates a Query Factory that does not have a specified representation of empty values and instead checks for the field value absence.

Parameters:

indexValueConverter - used for converting query literals to the index representation

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.

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.

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.

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.
