Exposed Java Runtime Classes

To help with debugging and to support some Lucene APIs, PyLucene also exposes some Java runtime APIs. As with the Java Lucene APIs, these APIs are fully documented on their development website at http://developer.classpath.org/doc/

     . java.lang.Object
          boolean equals(object)
          int hashCode()
          string toString()
          class getClass()
          void notify()
          void notifyAll()
          void wait()
          void wait(long)
          void wait(long, int)

     . java.lang.Thread
          Thread(runnable)
          Thread(runnable, string)
          string getName()
          boolean isAlive()
          boolean isDaemon()
          boolean isInterrupted()
          void setDaemon(boolean)
          void setName(string)
          void start()
          void join()
          void join(long)
          void join(long, int)

     . java.lang.Class
          string getName()
          boolean isArray()
          boolean isInterface()
          boolean isPrimitive()
          boolean isAssignableFrom(class)
          boolean isInstance(object)

     . java.lang.System
          static long currentTimeMillis()
          static void gc()
          static string getProperty(string)
          static string getProperty(string, string)
          static string setProperty(string, string)
          static java.util.Properties getProperties()
          static void load(string)
          static void loadLibrary(string)
          static void mapLibraryName(string)
          static void runFinalization()
          static jint identityHashCode(object)
          static java.io.PrintStream out
          static java.io.PrintStream err

     . java.lang.Process
          void destroy()
          jint exitValue()
          void waitFor()

     . java.lang.Runtime
          static Runtime getRuntime()
          long freeMemory()
          long totalMemory()
          long maxMemory()
          void gc()
          void runFinalization()
          int availableProcessors()
          void addShutdownHook(Thread)
          void removeShutdownHook(Thread)
          Process execute(string)
          Process execute(string[])
          Process execute(string, string[])
          Process execute(string[], string[])
          void traceInstructions(boolean)
          void traceMethodCalls(boolean)

       Because 'exec' is a keyword in Python, the exec() methods were
       renamed to 'execute'.

     . java.lang.Throwable
          Throwable getCause()
          string getLocalizedMessage()
          string getMessage()
          void printStackTrace()

     . java.io.Reader

       Instead of taking an array argument, the read() method returns a
       unicode string of the fully read stream. To only read a specific
       number of unicode characters, this methods also accepts a length
       argument.

     . java.io.OutputStream

     . java.io.FilterOutputStream

     . java.io.PrintStream
          void flush()
          void printString(string)
          void printObject(object)
          void println()
          void println(string)
          void println(object)

       Because 'print' is a reserved word in Python, the print(string) and
       print(object) methods were renamed to 'printString' and
       'printObject' respectively.

     . java.util.Locale
          Locale(string, string, string)
          Locale(string, string)
          Locale(string)
          static Locale getDefault()
          static void setDefault(Locale)
          static Locale[] getAvailableLocales()
          static string[] getISOCountries()
          static string[] getISOLanguages()
          string getLanguage()
          string getCountry()
          string getVariant()
          string getISO3Language()
          string getISO3Country()
          string getDisplayLanguage()
          string getDisplayLanguage(Locale)
          string getDisplayCountry()
          string getDisplayCountry(Locale)
          string getDisplayVariant()
          string getDisplayVariant(Locale)
          string getDisplayName()
          string getDisplayName(Locale)
          static Locale ENGLISH
          static Locale FRENCH
          static Locale GERMAN
          static Locale ITALIAN
          static Locale JAPANESE

          static Locale CANADA
          static Locale CANADA_FRENCH

     . java.util.BitSet
          BitSet()
          BitSet(int)
          void andSet(BitSet)
          void andNot(BitSet)
          int cardinality()
          void clear()
          void clear(int)
          void clear(int, int)
          void flip(int)
          void flip(int, int)
          boolean get(int)
          BitSet get(int, int)
          boolean intersects(BitSet)
          boolean isEmpty()
          jint length()
          jint nextClearBit(jint)
          jint nextSetBit(jint)
          void orSet(BitSet)
          void set(int)
          void set(int, boolean)
          void set(int, int)
          void set(int, int, boolean)
          int size()
          void xorSet(BitSet)

       Because 'and', 'or' and 'xor' are reserved words in Python, the
       corresponding BitSet methods were renamed 'andSet', 'orSet' and
       'xorSet' respectively.

     . java.util.Date
          Date()
          Date(long)

          int getMinimalDaysInFirstWeek()
          int getMinimum(int)
          int getMaximum(int)
          int getGreatestMinimum(int)

          static int AM
          static int PM

       The following downcast and type checking methods are also included:
          GregorianCalendar toGregorianCalendar()
          boolean isGregorianCalendar()

     . java.util.GregorianCalendar
          GregorianCalendar()
          GregorianCalendar(int, int, int)
          GregorianCalendar(int, int, int, int, int)
          GregorianCalendar(int, int, int, int, int, int)
          GregorianCalendar(jlocale)

          string getProperty(string, string)
          object setProperty(string, string)
          stringEnumeration propertyNames()

       The Properties class partially implements the Python 'dict'
       protocol.

           The Java expressions:

               props.getProperty("title")
               props.getProperty("title", "default")
               props.setProperty("title", "foo")
               props.containsKey("title")

           are better written in Python:

               props['title']
               props.get('title', 'default')
               props['title'] = 'foo'
