Class Options

  • public class Options
extends java.lang.Object
    A class with static fields for each of the settable options. The options from registry and command line is copied into the fields here and the rest of Jython checks these fields.

    • Field Summary

      Fields 
      Modifier and Type Field Description
      static int bytes_warning  
      static boolean caseok
      If true, Jython will use the first module found on sys.path where java File.isFile() returns true.

      Enable division warning.
      static boolean dont_write_bytecode
      Whether -B (don't write bytecode on import) was enabled via the command line.
      static boolean ignore_environment
      Whether -E (ignore environment) was enabled via the command line.
      static boolean importSite
      When false the site.py will not be imported.
      static boolean includeJavaStackInExceptions
      If true, exceptions raised from Python code will include a Java stack trace in addition to the Python traceback.

      static boolean no_user_site  
      static int optimize  
      static java.lang.String proxyDebugDirectory
      A directory where the dynamically generated classes are written.
      static boolean py3k_warning
      Whether -3 (py3k warnings) was enabled via the command line.
      static boolean Qnew
      If true, enable truedivision for the '/' operator.
      static boolean respectJavaAccessibility
      If true, Jython respects Java the accessibility flag for fields, methods, and constructors.
      static boolean showJavaExceptions
      when an exception occurs in Java code, and it is not caught, should the interpreter print out the Java exception in the traceback?
      static boolean showPythonProxyExceptions
      When true, python exception raised in overridden methods will be shown on stderr.
      static java.lang.String sreCacheSpec  
      static java.lang.String sreCacheSpecDefault
      Cache spec for the SRE_STATE code point cache.
      static boolean unbuffered
      Force stdin, stdout and stderr to be unbuffered, and opened in binary mode
      static int verbose
      Set verbosity to Py.ERROR, Py.WARNING, Py.MESSAGE, Py.COMMENT, or Py.DEBUG for varying levels of informative messages from Jython.

    • Method Summary

      All Methods Static Methods Concrete Methods 
      Modifier and Type Method Description
      static void setFromRegistry()
      Initialize the static fields from the registry options.

      • Methods inherited from class java.lang.Object

        equals, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait

    • Field Detail

      • showJavaExceptions

        public static boolean showJavaExceptions
        when an exception occurs in Java code, and it is not caught, should the interpreter print out the Java exception in the traceback?

      • includeJavaStackInExceptions

        public static boolean includeJavaStackInExceptions
        If true, exceptions raised from Python code will include a Java stack trace in addition to the Python traceback. This can slow raising considerably.

      • showPythonProxyExceptions

        public static boolean showPythonProxyExceptions
        When true, python exception raised in overridden methods will be shown on stderr. This option is remarkably useful when python is used for implementing CORBA server. Some CORBA servers will turn python exception (say a NameError) into an anonymous user exception without any stacktrace. Setting this option will show the stacktrace.

      • respectJavaAccessibility

        public static boolean respectJavaAccessibility
        If true, Jython respects Java the accessibility flag for fields, methods, and constructors. This means you can only access public members. Set this to false to access all members by toggling the accessible flag on the member.

      • importSite

        public static boolean importSite
        When false the site.py will not be imported. This is only honored by the command line main class.

      • verbose

        public static int verbose
        Set verbosity to Py.ERROR, Py.WARNING, Py.MESSAGE, Py.COMMENT, or Py.DEBUG for varying levels of informative messages from Jython. Normally this option is set from the command line.

      • proxyDebugDirectory

        public static java.lang.String proxyDebugDirectory
        A directory where the dynamically generated classes are written. Nothing is ever read from here, it is only for debugging purposes.

      • caseok

        public static boolean caseok
        If true, Jython will use the first module found on sys.path where java File.isFile() returns true. Setting this to true have no effect on unix-type filesystems. On Windows/HFS+ systems setting it to true will enable Jython-2.0 behaviour.

      • Qnew

        public static boolean Qnew
        If true, enable truedivision for the '/' operator.

      • unbuffered

        public static boolean unbuffered
        Force stdin, stdout and stderr to be unbuffered, and opened in binary mode

      • py3k_warning

        public static boolean py3k_warning
        Whether -3 (py3k warnings) was enabled via the command line.

      • dont_write_bytecode

        public static boolean dont_write_bytecode
        Whether -B (don't write bytecode on import) was enabled via the command line.

      • ignore_environment

        public static boolean ignore_environment
        Whether -E (ignore environment) was enabled via the command line.

      • no_user_site

        public static boolean no_user_site

      • no_site

        public static boolean no_site

      • bytes_warning

        public static int bytes_warning

      • optimize

        public static int optimize

      • division_warning

        public static int division_warning
        Enable division warning. The value maps to the registry values of
        • old: 0
        • warn: 1
        • warnall: 2

      • sreCacheSpecDefault

        public static final java.lang.String sreCacheSpecDefault
        Cache spec for the SRE_STATE code point cache. The value maps to the CacheBuilderSpec string and affects how the SRE_STATE cache will behave/evict cached PyString -> int[] code points.

      • setFromRegistry

        public static void setFromRegistry()
        Initialize the static fields from the registry options.
