public class OperatorBetween
extends Operator

Represents the between operator. The left operand to between must be a single value and the right operand must be a list - this operator returns true if the left operand is between (using the registered comparator) the two elements in the list. The definition of between being inclusive follows the SQL BETWEEN definition.

Method Detail

getValueInternal

public BooleanTypedValue getValueInternal(ExpressionState state)
                                   throws EvaluationException

Returns a boolean based on whether a value is in the range expressed. The first operand is any value whilst the second is a list of two values - those two values being the bounds allowed for the first operand (inclusive).

Specified by:

getValueInternal in class SpelNodeImpl

Parameters:

state - the expression state

Returns:

true if the left operand is in the range specified, false otherwise

Throws:

EvaluationException - if there is a problem evaluating the expression
