Represents the bit-wise operators in an expression tree.

  • Constructor Details

    • ExprBitWiseNode

      public ExprBitWiseNode(BitWiseOpEnum bitWiseOpEnum)
      Ctor.
      Parameters:
      bitWiseOpEnum - - type of math

  • Method Details

    • getExprEvaluator

      public ExprEvaluator getExprEvaluator()

    • getForge

      public ExprForge getForge()

    • getBitWiseOpEnum

      public BitWiseOpEnum getBitWiseOpEnum()
      Returns the bitwise operator.
      Returns:
      operator

    • validate

      public ExprNode validate(ExprValidationContext validationContext) throws ExprValidationException
      Throws:
      ExprValidationException

    • isConstantResult

      public boolean isConstantResult()

    • equalsNode

      public boolean equalsNode(ExprNode node, boolean ignoreStreamPrefix)
      Description copied from interface: ExprNode
      Return true if a expression node semantically equals the current node, or false if not.

      Concrete implementations should compare the type and any additional information that impact the evaluation of a node.

      Parameters:
      node - to compare to
      ignoreStreamPrefix - when the equals-comparison can ignore prefix of event properties
      Returns:
      true if semantically equal, or false if not equals

      public void toPrecedenceFreeEPL(StringWriter writer, ExprNodeRenderableFlags flags)
      Specified by:
      toPrecedenceFreeEPL in class ExprNodeBase

    • getPrecedence

      public ExprPrecedenceEnum getPrecedence()
      Description copied from interface: ExprNode
      Returns precedence.
      Returns:
      precedence
