class AtomicInteger(initial=0)

AtomicInteger is an Integer which can work atomically.

get_and_increment()

Returns the current value and increment it.

Returns

(int), current value of AtomicInteger.

set(value)

Sets the value of this AtomicInteger. :param value: (int), the new value of AtomicInteger.

get_possible_addresses(addresses=[], member_list=[])
get_provider_addresses(providers=[])
parse_addresses(addresses=[])
class ImmutableLazyDataList(list_data, to_object)

Bases: collections.abc.Sequence

get_portable_version(portable, default_version)
class TimeUnit

Bases: object

Represents the time durations at given units in seconds.

NANOSECOND = 1e-09
MICROSECOND = 1e-06
MILLISECOND = 0.001
SECOND = 1.0
MINUTE = 60.0
HOUR = 3600.0
static to_seconds(value, time_unit)
Parameters

  • value – (Number), value to be translated to seconds

  • time_unit – Time duration in seconds

Returns

Value of the value in seconds

calculate_version(version_str)
class VersionMessageFilter(name='')

Bases: logging.Filter

Initialize a filter.

Initialize with the name of the logger which, together with its children, will have its events allowed through the filter. If no name is specified, allow every event.

filter(record)

Determine if the specified record is to be logged.

Is the specified record to be logged? Returns 0 for no, nonzero for yes. If deemed appropriate, the record may be modified in-place.

class HazelcastFormatter(fmt=None, datefmt=None, style='%')

Bases: logging.Formatter

Initialize the formatter with specified format strings.

Initialize the formatter either with the specified format string, or a default as described above. Allow for specialized date formatting with the optional datefmt argument. If datefmt is omitted, you get an ISO8601-like (or RFC 3339-like) format.

Use a style parameter of ‘%’, ‘{‘ or ‘$’ to specify that you want to use one of %-formatting, str.format() ({}) formatting or string.Template formatting in your format string.

Changed in version 3.2: Added the style parameter.

format(record)

Format the specified record as text.

The record’s attribute dictionary is used as the operand to a string formatting operation which yields the returned string. Before formatting the dictionary, a couple of preparatory steps are carried out. The message attribute of the record is computed using LogRecord.getMessage(). If the formatting string uses the time (as determined by a call to usesTime(), formatTime() is called to format the event time. If there is exception information, it is formatted using formatException() and appended to the message.
