All Implemented Interfaces:

Opcodes, SpelNode

public class OperatorMatches
extends Operator

Implements the matches operator. Matches takes two operands: The first is a String and the second is a Java regex. It will return true when SpelNodeImpl.getValue(org.springframework.expression.spel.ExpressionState) is called if the first operand matches the regex.

3.0

Method Details

getValueInternal

public BooleanTypedValue getValueInternal(ExpressionState state)
                                   throws EvaluationException

Check the first operand matches the regex specified as the second operand.

Specified by:

getValueInternal in class SpelNodeImpl

Parameters:

state - the expression state

Returns:

true if the first operand matches the regex specified as the second operand, otherwise false

Throws:

EvaluationException - if there is a problem evaluating the expression (e.g. the regex is invalid)
