Method Detail

validate

public MessageSet validate(ApplicationUser searcher,
                           FunctionOperand operand,
                           TerminalClause terminalClause)

Description copied from interface: JqlFunction

Will validate the function operand's arguments and report back any errors.

Parameters:

searcher - the user performing the search

operand - the operand to validate

terminalClause - the terminal clause that contains the operand

Returns:

a MessageSet which will contain any validation errors or warnings or will be empty if there is nothing to report; never null.

getValues

public List<QueryLiteral> getValues(QueryCreationContext queryCreationContext,
                                    FunctionOperand operand,
                                    TerminalClause terminalClause)

Description copied from interface: JqlFunction

Gets the unexpanded values provided by the user on input. This is the output values that will later be transformed into index values.

For example, a function who returns all the released versions of a specified project should return QueryLiterals representing the ids of those versions. For correctness, always opt to return the most specific identifier for the object; if you can return either the id (which is stored in the index) or a string name (that would require resolving to get the index value), choose the id.

Parameters:

queryCreationContext - the context of query creation

operand - the operand to get values from

terminalClause - the terminal clause that contains the operand

Returns:

a List of objects that represent this Operands raw values. Cannot be null.

getMinimumNumberOfExpectedArguments

public int getMinimumNumberOfExpectedArguments()

Description copied from interface: JqlFunction

This method must return the number of arguments that the function expects to perform its operation correctly. If the function can accept a variable number of arguments this value should be the lower limit. It is perfectly legal for a function to take no arguments and return 0 for this method.

Returns:

the number of arguments that the function expects to perform its operation correctly. Must be >=0.

getDataType

public JiraDataType getDataType()

Description copied from interface: JqlFunction

Provides the JiraDataType that this function handles and creates values for. This allows us to infer some information about how it will interact with other elements in the system.

For example, if this returns JiraDataTypes.DATE then we know that we can provide values for any clauses that also specify a data type of DATE.

Returns:

the JiraDataType that this function produces values for. Cannot be null.
