Class OperatorMatches

java.lang.Object
org.springframework.expression.spel.ast.SpelNodeImpl
org.springframework.expression.spel.ast.Operator
org.springframework.expression.spel.ast.OperatorMatches
All Implemented Interfaces:
org.springframework.asm.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.

    • 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)
