public class OperatorBetween
extends Operator

Represents the between operator.

The left operand must be a single value, and the right operand must be a 2-element list which defines a range from a lower bound to an upper bound.

This operator returns true if the left operand is greater than or equal to the lower bound and less than or equal to the upper bound. Consequently, 1 between {1, 5} evaluates to true, while 1 between {5, 1} evaluates to false.

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 lower and upper 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
