Class DefaultIndexedInputHelper<T>

java.lang.Object
  com.atlassian.jira.issue.search.searchers.util.DefaultIndexedInputHelper<T>

All Implemented Interfaces:

IndexedInputHelper

Direct Known Subclasses:

ComponentIndexedInputHelper, IssueConstantIndexedInputHelper, VersionIndexedInputHelper

@NonInjectableComponent
public class DefaultIndexedInputHelper<T>
extends Object
implements IndexedInputHelper

The default implementation for the IndexedInputHelper.

This class should be constructed as needed and not injected, as the IndexInfoResolver is only relevant to specific field(s).

Since:

v4.0

Constructor Summary

DefaultIndexedInputHelper(IndexInfoResolver<T> indexInfoResolver, JqlOperandResolver operandResolver, FieldFlagOperandRegistry fieldFlagOperandRegistry, SearchContextVisibilityChecker searchContextVisibilityChecker)

Method Summary

protected SingleValueOperand	createSingleValueOperandFromId(String stringValue) Resolve this string representation of a navigator value (known not to be a field flag) into an operand to be used in a clause.
Set<String>	getAllIndexValuesForMatchingClauses(com.atlassian.crowd.embedded.api.User searcher, ClauseNames jqlClauseNames, Query query, SearchContext searchContext) Retrieves the index values for the clauses in the SearchRequest.
Set<String>	getAllNavigatorValuesForMatchingClauses(com.atlassian.crowd.embedded.api.User searcher, ClauseNames jqlClauseNames, Query query, SearchContext searchContext) Retreives the navigator id values for the values in the clauses.
Clause	getClauseForNavigatorValues(String clauseName, Set<String> values) Converts a set of Navigator value strings into a Clause that will match at least one of the specified values for the given field.

Method Detail

getAllIndexValuesForMatchingClauses

public Set<String> getAllIndexValuesForMatchingClauses(com.atlassian.crowd.embedded.api.User searcher,
                                                       ClauseNames jqlClauseNames,
                                                       Query query,
                                                       SearchContext searchContext)

Description copied from interface: IndexedInputHelper

Retrieves the index values for the clauses in the SearchRequest. Function Operands are expanded to their values.

Specified by:

getAllIndexValuesForMatchingClauses in interface IndexedInputHelper

Parameters:

searcher - the user running the search

jqlClauseNames - the names of the clauses on which to retreive the values.

query - the search criteria used to populate the field values holder.

searchContext - the context under which the search is being performed

Returns:

a set of strings containing the index values of the clause values. Never null.

getAllNavigatorValuesForMatchingClauses

public Set<String> getAllNavigatorValuesForMatchingClauses(com.atlassian.crowd.embedded.api.User searcher,
                                                           ClauseNames jqlClauseNames,
                                                           Query query,
                                                           SearchContext searchContext)

Description copied from interface: IndexedInputHelper

Retreives the navigator id values for the values in the clauses. If there is a flag associated with a function operand then that flag is returned, otherwise the function operand is expanded to its index values.

Specified by:

getAllNavigatorValuesForMatchingClauses in interface IndexedInputHelper

Parameters:

searcher - the user running the search

jqlClauseNames - the names of the clauses on which to retreive the values.

query - the search criteria used to populate the field values holder.

searchContext - the context under which the search is being performed

Returns:

a set of strings containing the navigator values of the clause values. Never Null.

getClauseForNavigatorValues

public Clause getClauseForNavigatorValues(String clauseName,
                                          Set<String> values)

Description copied from interface: IndexedInputHelper

Converts a set of Navigator value strings into a Clause that will match at least one of the specified values for the given field.

Note: where possible, the helper should try to create a clause, even when the value strings do not make sense in the given domain. That is, it is preferred that a non-validating clause gets created than no clause at all.

Specified by:

getClauseForNavigatorValues in interface IndexedInputHelper

Parameters:

clauseName - the name of the clause to generate

values - a set of Navigator value strings; may contain flag values. May not be null.

Returns:

a clause that will match any of the values specified; null if no values were specified.

createSingleValueOperandFromId

protected SingleValueOperand createSingleValueOperandFromId(String stringValue)

Resolve this string representation of a navigator value (known not to be a field flag) into an operand to be used in a clause. Override this to provide domain-specific resolution (e.g. resolve version ids to names).

Parameters:

stringValue - the navigator value as a string e.g. 123

Returns:

the operand which best represents this navigator value - either a string name or the id or whatever.
