Method Detail

validate

public MessageSet validate(com.atlassian.crowd.embedded.api.User searcher,
                           SingleValueOperand operand,
                           TerminalClause terminalClause)
Description copied from interface: OperandHandler
Will perform operand specific validation.

Specified by:
validate in interface OperandHandler<SingleValueOperand>
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, must not be null.

getValues

public List<QueryLiteral> getValues(QueryCreationContext queryCreationContext,
                                    SingleValueOperand operand,

getValues in interface OperandHandler<SingleValueOperand>
Parameters:
queryCreationContext - the context of query creation
operand - the operand to get values from
terminalClause - the terminal clause that contains the operand

isList in interface OperandHandler<SingleValueOperand>
Returns:
true if the operand represents a list of values, false otherwise.

isEmpty

public boolean isEmpty()
Specified by:
isEmpty in interface OperandHandler<SingleValueOperand>
Returns:
true if the operand represents the absence of a value, false otherwise. EmptyOperand

isFunction
