    - #### getLength

          public int getLength()

      Returns the length of this path.
      返回:
        the length of this path.

    - #### getStep

          public int getStep(int index)

      Returns the value of the given step of this path.
      参数:
        `index` - an index between 0 and `getLength()`, exclusive.
      返回:
        `ARRAY_ELEMENT`, `INNER_TYPE`, `WILDCARD_BOUND`, or `TYPE_ARGUMENT`.

    - #### getStepArgument

          public int getStepArgument(int index)

      Returns the index of the type argument that the given step is stepping into. This method should only be used for steps whose value is `TYPE_ARGUMENT`.
      参数:
        `index` - an index between 0 and `getLength()`, exclusive.
      返回:
        the index of the type argument that the given step is stepping into.

    - #### fromString

          public static TypePath fromString(String typePath)

      Converts a type path in string form, in the format used by `toString()`, into a TypePath object.
      参数:
        `typePath` - a type path in string form, in the format used by `toString()`. May be null or empty.
      返回:
        the corresponding TypePath object, or null if the path is empty.

    - #### toString

          public String toString()

      Returns a string representation of this type path. `ARRAY_ELEMENT` steps are represented with '[', `INNER_TYPE` steps with '.', `WILDCARD_BOUND` steps with '*' and `TYPE_ARGUMENT` steps with their type argument index in decimal form followed by ';'.
