Record Class Unary

java.lang.Object
java.lang.Record
com.libdbm.cel.ast.Unary
Record Components:
op - the unary operator to apply
operand - the operand expression the operator applies to
All Implemented Interfaces:
Expression
public record Unary(UnaryOp op, Expression operand) extends Record implements Expression
Represents a unary operation in CEL expressions.

Supported operations include logical NOT (!) and numeric negation (-).

  • Constructor Details

    • Unary

      public Unary(UnaryOp op, Expression operand)
      Creates an instance of a Unary record class.
      Parameters:
      op - the value for the op record component
      operand - the value for the operand record component

  • Method Details

    • accept

      public <T> T accept(Expression.Visitor<T> visitor)
      Accepts a visitor to perform operations on this expression node.

      Invokes the appropriate visit method on the provided visitor, dispatching the visit operation to the visitor implementation that corresponds to the type of this expression node.

      Specified by:
      accept in interface Expression
      Type Parameters:
      T - the return type of the visitor's visit operations
      Parameters:
      visitor - the visitor that will operate on this expression node
      Returns:
      the result of the visitor's visit operation

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.

    • op

      public UnaryOp op()
      Returns the value of the op record component.
      Returns:
      the value of the op record component

    • operand

      public Expression operand()
      Returns the value of the operand record component.
      Returns:
      the value of the operand record component
