Method Details

getDetailedGcLoggingArgs

public static List<String> getDetailedGcLoggingArgs()

Gets GC logging JVM params

Returns:

list of JVM args for GC logging.

checkJvmArgBlacklist

public static void checkJvmArgBlacklist(String... extraJvmArgs)

Check whether any illegal JVM arguments have been specified. This defaults to 'security properties may not be altered at runtime' but can be configured with the 'jvm.blacklist' property.

Parameters:

extraJvmArgs - The list of requested additional JVM arguments being checked for invalid values.

Throws:

IllegalArgumentException - if a blacklisted property is found.

getUserExtraJvmArgs

public static List<String> getUserExtraJvmArgs(RemoteProcessingRequest request)

asJvmPropertyArg

public static String asJvmPropertyArg(String property,
 String value)

Takes two strings, a property name and property value, respectively, and formats them as a string suitable for use as a JVM argument, e.g. -Dproperty=value. The property must be non-null. If the value is null a blank value will be used.

Parameters:

property - property name to be defined

value - property value

Returns:

String formatted for use as a JVM arg.

Throws:

NullPointerException - if value is null

createPersistentQueryHandle

@NotNull
public static Object createPersistentQueryHandle(@NotNull
 String className,
 @NotNull
 com.fishlib.io.logger.Logger log,
 @NotNull
 Object queryHandleContext)
                                          throws UncheckedDeephavenException

Convenience method to instantiate a persistent query handle. Used by WorkerKind implementations.

Parameters:

className - Name of class to instantiate

log - Logger object used as first constructor arg

queryHandleContext - Object used as second constructor arg

Returns:

The instantiated PersistentQueryHandle

Throws:

UncheckedDeephavenException - if the handle could not be created.
