Description copied from class: DFOperator

Validate the operands in context of this operator. It's up to operator to decide if it accepts the given operands or not. This method is called from DFTerm.validate(com.im.df.api.ddl.DFDataTree).

Overrides:

validate in class Operators.SimpleFieldValuesOperator

Parameters:

dataTree - The datatree where this operator will be used

operands - The list of operands

options - Options of this query term (DFTermExpression.getOptions()

errors - The errors object which contains the result of the validation

isEmptyStringAllowed

protected boolean isEmptyStringAllowed()

Overrides:
