When not compiling, does\n  nothing. The gen-class construct contains no implementation, as the\n  implementation will be dynamically sought by the generated class in\n  functions in an implementing Clojure namespace. Given a generated\n  class org.mydomain.MyClass with a method named mymethod, gen-class\n  will generate an implementation that looks for a function named by \n  (str prefix mymethod) (default prefix: \"-\") in a\n  Clojure namespace specified by :impl-ns\n  (defaults to the current namespace). All inherited methods,\n  generated methods, and init and main functions (see :methods, :init,\n  and :main below) will be found similarly prefixed. By default, the\n  static initializer for the generated class will attempt to load the\n  Clojure support code for the class as a resource from the classpath,\n  e.g. in the example case, ``org/mydomain/MyClass__init.class``. This\n  behavior can be controlled by :load-impl-ns\n\n  Note that methods with a maximum of 18 parameters are supported.\n\n  In all subsequent sections taking types, the primitive types can be\n  referred to by their Java names (int, float etc), and classes in the\n  java.lang package can be used without a package qualifier. All other\n  classes must be fully qualified.\n\n  Options should be a set of key/value pairs, all except for :name are optional:\n\n  :name aname\n\n  The package-qualified name of the class to be generated\n\n  :extends aclass\n\n  Specifies the superclass, the non-private methods of which will be\n  overridden by the class. If not provided, defaults to Object.\n\n  :implements [interface ...]\n\n  One or more interfaces, the methods of which will be implemented by the class.\n\n  :init name\n\n  If supplied, names a function that will be called with the arguments\n  to the constructor. Must return [ [superclass-constructor-args] state] \n  If not supplied, the constructor args are passed directly to\n  the superclass constructor and the state will be nil\n\n  :constructors {[param-types] [super-param-types], ...}\n\n  By default, constructors are created for the generated class which\n  match the signature(s) of the constructors for the superclass. This\n  parameter may be used to explicitly specify constructors, each entry\n  providing a mapping from a constructor signature to a superclass\n  constructor signature. When you supply this, you must supply an :init\n  specifier. \n\n  :post-init name\n\n  If supplied, names a function that will be called with the object as\n  the first argument, followed by the arguments to the constructor.\n  It will be called every time an object of this class is created,\n  immediately after all the inherited constructors have completed.\n  Its return value is ignored.\n\n  :methods [ [name [param-types] return-type], ...]\n\n  The generated class automatically defines all of the non-private\n  methods of its superclasses/interfaces. This parameter can be used\n  to specify the signatures of additional methods of the generated\n  class. Static methods can be specified with ^{:static true} in the\n  signature's metadata. Do not repeat superclass/interface signatures\n  here.\n\n  :main boolean\n\n  If supplied and true, a static public main function will be generated. It will\n  pass each string of the String[] argument as a separate argument to\n  a function called (str prefix main).\n\n  :factory name\n\n  If supplied, a (set of) public static factory function(s) will be\n  created with the given name, and the same signature(s) as the\n  constructor(s).\n  \n  :state name\n\n  If supplied, a public final instance field with the given name will be\n  created. You must supply an :init function in order to provide a\n  value for the state. Note that, though final, the state can be a ref\n  or agent, supporting the creation of Java objects with transactional\n  or asynchronous mutation semantics.\n\n  :exposes {protected-field-name {:get name :set name}, ...}\n\n  Since the implementations of the methods of the generated class\n  occur in Clojure functions, they have no access to the inherited\n  protected fields of the superclass. This parameter can be used to\n  generate public getter/setter methods exposing the protected field(s)\n  for use in the implementation.\n\n  :exposes-methods {super-method-name exposed-name, ...}\n\n  It is sometimes necessary to call the superclass' implementation of an\n  overridden method.  Those methods may be exposed and referred in \n  the new method implementation by a local name.\n\n  :prefix string\n\n  Default: \"-\" Methods called e.g. Foo will be looked up in vars called\n  prefixFoo in the implementing ns.\n\n  :impl-ns name\n\n  Default: the name of the current ns. Implementations of methods will be \n  looked up in this namespace.\n\n  :load-impl-ns boolean\n\n  Default: true. Causes the static initializer for the generated class\n  to reference the load code for the implementing namespace.

WARNING: You SHOULD NOT use clojure.core/read or\n;; clojure.core/read-string to read data from untrusted sources.  They\n;; were designed only for reading Clojure code and data from trusted\n;; sources (e.g. files that you know you wrote yourself, and no one\n;; else has permission to modify them).\n\n;; Instead, either:\n\n;; (1) Use another data serialization format such as JSON, XML,\n;; etc. and a library for reading them that you trust not to have\n;; vulnerabilities, or\n\n;; (2) if you want a serialization format that can be read safely and\n;; looks like Clojure data structures, use edn\n;; (https://github.com/edn-format/edn).  For Clojure 1.3 and later,\n;; the tools.reader contrib library provides an edn reader\n;; (http://github.com/clojure/tools.reader).  There is also\n;; clojure.edn/read and clojure.edn/read-string provided in Clojure\n;; 1.5.\n\n;; You definitely should not use clojure.core/read or read-string if\n;; *read-eval* has its default value of true, because an attacker\n;; could cause your application to execute arbitrary code while it is\n;; reading.  Example:\n\nuser=\u003E (read-string \"#=(clojure.java.shell/sh \\\"echo\\\" \\\"hi\\\")\")\n{:exit 0, :out \"hi\\n\", :err \"\"}\n\n;; It is straightforward to modify the example above into more\n;; destructive ones that remove all of your files, copy them to\n;; someone else's computer over the Internet, install Trojans, etc.\n\n;; Even if you do bind *read-eval* to false first, like so:\n\n(defn read-string-unsafely [s]\n  (binding [*read-eval* false]\n    (read-string s)))\n\n;; you may hope you are safe reading untrusted data that way, but in\n;; Clojure 1.4 and earlier, an attacker can send data that causes your\n;; system to execute arbitrary Java constructors.  Most of these are\n;; benign, but it only takes one to ruin your application's day.\n;; Examples that should scare you:\n\n;; This causes a socket to be opened, as long as the JVM sandboxing\n;; allows it.\n(read-string-unsafely \"#java.net.Socket[\\\"www.google.com\\\" 80]\")\n\n;; This causes precious-file.txt to be created if it doesn't exist, or\n;; if it does exist, its contents will be erased (given appropriate\n;; JVM sandboxing permissions, and underlying OS file permissions).\n(read-string-unsafely \"#java.io.FileWriter[\\\"precious-file.txt\\\"]\")\n\n;; The particular issue of executing arbitrary Java constructors used\n;; in the examples above no longer works in Clojure 1.5 when\n;; *read-eval* is false.  Even so, you SHOULD NEVER USE\n;; clojure.core/read or clojure.core/read-string for reading untrusted\n;; data.

Each argument is\n  either a libspec that identifies a lib, a prefix list that identifies\n  multiple libs whose names share a common prefix, or a flag that modifies\n  how all the identified libs are loaded. Use :require in the ns macro\n  in preference to calling this directly.\n\n  Libs\n\n  A 'lib' is a named set of resources in classpath whose contents define a\n  library of Clojure code. Lib names are symbols and each lib is associated\n  with a Clojure namespace and a Java package that share its name. A lib's\n  name also locates its root directory within classpath using Java's\n  package name to classpath-relative path mapping. All resources in a lib\n  should be contained in the directory structure under its root directory.\n  All definitions a lib makes should be in its associated namespace.\n\n  'require loads a lib by loading its root resource. The root resource path\n  is derived from the lib name in the following manner:\n  Consider a lib named by the symbol 'x.y.z; it has the root directory\n  \u003Cclasspath\u003E/x/y/, and its root resource is \u003Cclasspath\u003E/x/y/z.clj, or\n  \u003Cclasspath\u003E/x/y/z.cljc if \u003Cclasspath\u003E/x/y/z.clj does not exist. The\n  root resource should contain code to create the lib's\n  namespace (usually by using the ns macro) and load any additional\n  lib resources.\n\n  Libspecs\n\n  A libspec is a lib name or a vector containing a lib name followed by\n  options expressed as sequential keywords and arguments.\n\n  Recognized options:\n  :as takes a symbol as its argument and makes that symbol an alias to the\n    lib's namespace in the current namespace.\n  :as-alias takes a symbol as its argument and aliases like :as, however\n    the lib will not be loaded. If the lib has not been loaded, a new\n    empty namespace will be created (as with create-ns).\n  :refer takes a list of symbols to refer from the namespace or the :all\n    keyword to bring in all public vars.\n\n  Prefix Lists\n\n  It's common for Clojure code to depend on several libs whose names have\n  the same prefix. When specifying libs, prefix lists can be used to reduce\n  repetition. A prefix list contains the shared prefix followed by libspecs\n  with the shared prefix removed from the lib names.
