  • Method Details

    • couldBeLambda

      public static boolean couldBeLambda(org.apache.bcel.classfile.Method m)
      Checks if the method could be a lambda. Notice this is a best-check, since once compiled lambda methods are not univocally distinguishable.
      Parameters:
      m - The method to check if it's a lambda
      Returns:
      True if this could be a lambda, false otherwise

    • couldBeLambda

      public static boolean couldBeLambda(XMethod m)
      Checks if the method could be a lambda. Notice this is a best-check, since once compiled lambda methods are not univocally distinguishable.
      Parameters:
      m - The method to check if it's a lambda
      Returns:
      True if this could be a lambda, false otherwise

    • couldBeLambda

      public static boolean couldBeLambda(org.apache.bcel.generic.MethodGen m)
      Checks if the method could be a lambda. Notice this is a best-check, since once compiled lambda methods are not univocally distinguishable.
      Parameters:
      m - The method to check if it's a lambda
      Returns:
      True if this could be a lambda, false otherwise

    • isUserGenerated

      public static boolean isUserGenerated(org.apache.bcel.classfile.FieldOrMethod m)
      Checks if the given method was user-generated. This takes into account for instance lambda methods, that even though they are marked as "synthetic", they are user-generated, and therefore interesting to analysis. Methods annotated with annotations such as Lombok's Generated are not considered user-generated.
      Parameters:
      m - The field or method to check.
      Returns:
      True if the given member is user generated, false otherwise.

    • isUserGenerated

      public static boolean isUserGenerated(ClassMember m)
      Checks if the given method was user-generated. This takes into account for instance lambda methods, that even though they are marked as "synthetic", they are user-generated, and therefore interesting to analysis. Methods annotated with annotations such as Lombok's Generated are not considered user-generated.
      Parameters:
      m - The field or method to check.
      Returns:
      True if the given member is user generated, false otherwise.

    • isUserGenerated

      public static boolean isUserGenerated(org.apache.bcel.generic.FieldGenOrMethodGen m)
      Checks if the given method was user-generated. This takes into account for instance lambda methods, that even though they are marked as "synthetic", they are user-generated, and therefore interesting to analysis. Methods annotated with annotations such as Lombok's Generated are not considered user-generated.
      Parameters:
      m - The field or method to check.
      Returns:
      True if the given member is user generated, false otherwise.

    • isUserGenerated

      public static boolean isUserGenerated(XClass c)
      Checks if the given class was user-generated, classes annotated with annotations such as Immutables' Generated are not considered user-generated.
      Parameters:
      c - The class to check.
      Returns:
      True if the given class is user generated, false otherwise.

    • isMainMethod

      public static boolean isMainMethod(org.apache.bcel.classfile.Method method)
      Checks if the given method is a main method. It takes into account the changes introduced in JEP 445. A main method has non-private access, is named "main", returns void, and has a single string array argument or has no arguments.
      Parameters:
      method - The method to check
      Returns:
      true if the method is a main method, false otherwise

    • isMainMethod

      public static boolean isMainMethod(XMethod method)
      Checks if the given method is a main method. It takes into account the changes introduced in JEP 445. A main method has non-private access, is named "main", returns void, and has a single string array argument or has no arguments.
      Parameters:
      method - The method to check
      Returns:
      true if the method is a main method, false otherwise
