    String
    getDisplayString()
    Produces the unexpanded representation of the Operand.
    String
    getName()
    The name that represents this Operand.

  • Method Details

    • getName

      String getName()
      The name that represents this Operand.
      Returns:
      the name of the operand, null if the operand is unnamed. If an operand is unnamed then it likely represents literal values (such as Strings or Longs).

    • getDisplayString

      String getDisplayString()
      Produces the unexpanded representation of the Operand. In the case of a function operand this would be the function as represented in the Query (i.e. group(jira-users)).
      Returns:
      a string that represents this operand as represented in the JQL query string.

    • accept

      <R> R accept(OperandVisitor<R> visitor)
      Allows us to perform operations over the operand based on the passed in visitor. This method calls the visit method on the visitor with this reference.
      Type Parameters:
      R - the return type for the visitor.
      Parameters:
      visitor - the visitor to accept.
      Returns:
      the result of the visit operation who's type is specified by the incomming visitor.
