Provides the
JiraDataType that this function handles and creates values for. |

getMinimumNumberOfExpectedArguments()
This method must return the number of arguments that the function expects to perform its operation correctly.

List<QueryLiteral> |
getValues(QueryCreationContext queryCreationContext,
FunctionOperand operand,
TerminalClause terminalClause)
Gets the unexpanded values provided by the user on input.
|
MessageSet |
validate(ApplicationUser searcher,
FunctionOperand operand,

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 QueryLiteral
s 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.

public JiraDataType getDataType()
JqlFunction
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.
