Method Detail

validate

public MessageSet validate(com.atlassian.crowd.embedded.api.User searcher,
                           FunctionOperand operand,
                           TerminalClause terminalClause)

Description copied from interface: OperandHandler

Will perform operand specific validation.

Specified by:

validate in interface OperandHandler<FunctionOperand>

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,
                                    FunctionOperand operand,
                                    TerminalClause terminalClause)

Description copied from interface: OperandHandler

Gets the unexpanded values provided by the user on input. In the case of a function this is the output values that will later be transformed into index values.

Specified by:

getValues in interface OperandHandler<FunctionOperand>

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. This must be the values specified by the user.

isList

public boolean isList()

Specified by:

isList in interface OperandHandler<FunctionOperand>

Returns:

true if the operand represents a list of values, false otherwise.

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface OperandHandler<FunctionOperand>

Returns:

true if the operand represents the absence of a value, false otherwise. EmptyOperand

isFunction

public boolean isFunction()

Specified by:

isFunction in interface OperandHandler<FunctionOperand>

Returns:

true if the operand represents a function, false otherwise. FunctionOperand

getJqlFunction

public JqlFunction getJqlFunction()
