+#   Package: NaturalDocs::Parser::ParsedTopic

+###############################################################################
+#
+#   A class for parsed topics of source files.  Also encompasses some of the <TopicType>-specific behavior.

+# Group: Implementation
+
+#
+#   Constants: Members
+#
+#   The object is a blessed arrayref with the following indexes.
+#
+#       TYPE           - The <TopicType>.
+#       TITLE          - The title of the topic.
+#       PACKAGE    - The package <SymbolString> the topic appears in, or undef if none.
+#       USING         - An arrayref of additional package <SymbolStrings> available to the topic via "using" statements, or undef if
+#                           none.
+#       PROTOTYPE - The prototype, if it exists and is applicable.
+#       SUMMARY    - The summary, if it exists.
+#       BODY          - The body of the topic, formatted in <NDMarkup>.  Some topics may not have bodies, and if not, this
+#                           will be undef.
+#       LINE_NUMBER  - The line number the topic appears at in the file.
+#       IS_LIST - Whether the topic is a list.
+#

+# DEPENDENCY: New() depends on the order of these constants, and that this class is not inheriting any members.

+# Group: Functions
+
+#
+#   Function: New
+#
+#   Creates a new object.
+#
+#   Parameters:
+#
+#       type          - The <TopicType>.
+#       title           - The title of the topic.
+#       package    - The package <SymbolString> the topic appears in, or undef if none.
+#       using         - An arrayref of additional package <SymbolStrings> available to the topic via "using" statements, or undef if none.
+#       prototype   - The prototype, if it exists and is applicable.  Otherwise set to undef.
+#       summary   - The summary of the topic, if any.
+#       body          - The body of the topic, formatted in <NDMarkup>.  May be undef, as some topics may not have bodies.
+#       lineNumber - The line number the topic appears at in the file.
+#       isList          - Whether the topic is a list topic or not.
+#
+#   Returns:
+#
+#       The new object.
+#

+#   Function: Symbol

+#
+#       - If the <TopicType> is always global, the symbol will be generated from the title only.

+#
+#   Returns the package <SymbolString> that the topic appears in.

+#       - If the <TopicType> has scope, the package will be generated from both the title and the package passed to <New()>, not
+#         just the package.
+#       - If the <TopicType> is always global, the package will be the one passed to <New()>, even though it isn't part of it's
+#         <Symbol()>.
+#       - Everything else's package will be what was passed to <New()>, even if the title has separator symbols in it.
