Method Detail

validate

public MessageSet validate(com.opensymphony.user.User 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.

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.
