  • Field Details

    • s_variantMap

      private static HashMap s_variantMap
      Map for primitive type signature variants.

    • s_signatureMap

      private static HashMap s_signatureMap
      Map for signatures corresponding to class names.

  • Constructor Details

      public ClassUtils()

  • Method Details

    • isPrimitive

      public static boolean isPrimitive(String type)
      Check if type name is a primitive.
      Parameters:
      type -
      Returns:
      true if a primitive, false if not

    • findVirtualMethod

      public static IClassItem findVirtualMethod(String name, String[] sigs, ValidationContext vctx)
      Get virtual method by fully qualified name. This splits the class name from the method name, finds the class, and then tries to find a matching method name in that class or a superclass.
      Parameters:
      name - fully qualified class and method name
      sigs - possible method signatures
      vctx - validation context (used for class lookup)
      Returns:
      information for the method, or null if not found

    • findStaticMethod

      public static IClassItem findStaticMethod(String name, String[] sigs, ValidationContext vctx)
      Get static method by fully qualified name. This splits the class name from the method name, finds the class, and then tries to find a matching method name in that class.
      Parameters:
      name - fully qualified class and method name
      sigs - possible method signatures
      vctx - validation context (used for class lookup)
      Returns:
      information for the method, or null if not found

    • getSignatureVariants

      public static String[] getSignatureVariants(String name, ValidationContext vctx)
      Get all variant signatures for a fully qualified class name. The returned array gives all signatures (for interfaces or classes) which instances of the class can match.
      Parameters:
      name - fully qualified class name
      vctx - validation context (used for class lookup)
      Returns:
      possible signature variations for instances of the class

    • getSignature

      public static String getSignature(String type)
      Gets the signature string corresponding to a type. The base for the type may be a primitive or class name, and may include trailing array brackets.
      Parameters:
      type - type name
      Returns:
      signature string for type

    • isAssignable

      public static boolean isAssignable(String from, String to, ValidationContext vctx)
      Check if a value of one type can be directly assigned to another type. This is basically the equivalent of the instanceof operator, but with application to primitive types as well as object types.
      Parameters:
      from - fully qualified class name of initial type
      to - fully qualified class name of assignment type
      vctx - validation context (used for class lookup)
      Returns:
      true if assignable, false if not
