class pygridgain.datatypes.standard.BinaryEnumArrayObject

Bases: EnumArrayObject

standard_type

alias of BinaryEnumObject

class pygridgain.datatypes.standard.BinaryEnumObject

Bases: EnumObject

Another way of representing the enum type. Same, but different.

alias of DateObject

class pygridgain.datatypes.standard.DateArrayObject

Bases: StandardArrayObject

List of datetime.datetime type values.

standard_type

alias of DateObject

type_code = b'\x16'
class pygridgain.datatypes.standard.DateObject

Bases: StandardObject

A signed integer number of milliseconds past 1 Jan 1970, aka Epoch (8 bytes long integer).

Represented as a naive datetime.datetime in Python.

classmethod build_c_type()
default = datetime.datetime(1970, 1, 1, 0, 0)
classmethod from_python_not_null(stream, value: date | datetime, **kwargs)
classmethod hashcode(value: datetime, **kwargs) → int

Bases: StandardArrayObject

List of decimal.Decimal objects.

class pygridgain.datatypes.standard.EnumArray

Bases: StandardArray

standard_type

alias of EnumObject

class pygridgain.datatypes.standard.EnumArrayObject

Bases: StandardArrayObject

Array of (int, int) tuples, plus it holds a type_id in its header. The only type_id value of -1 (user type) works from Python perspective.

OBJECT = -1
classmethod from_python_not_null(stream, value, **kwargs)
standard_type

alias of EnumObject

classmethod to_python_not_null(ctypes_object, **kwargs)
type_code = b'\x1d'
class pygridgain.datatypes.standard.EnumObject

Bases: StandardObject

Two integers used as the ID of the enumeration type, and its value.

This type itself is useless in Python, but can be used for interoperability (using language-specific type serialization is a good way to kill the interoperability though), so it represented by tuple(int, int) in Python.

classmethod build_c_type()
classmethod from_python_not_null(stream, value: tuple, **kwargs)
classmethod to_python_not_null(ctypes_object, **kwargs)
type_code = b'\x1c'
class pygridgain.datatypes.standard.ObjectArray

Bases: EnumArrayObject

standard_type

alias of BinaryEnumObject

class pygridgain.datatypes.standard.String

Bases: Nullable

Pascal-style string: c_int counter, followed by count*bytes. UTF-8-encoded, so that one character may take 1 to 4 bytes.

classmethod build_c_type(length: int)
classmethod from_python_not_null(stream, value, **kwargs)
classmethod hashcode(value: str, **kwargs) → int
classmethod parse_not_null(stream)
pythonic

alias of str

classmethod to_python_not_null(ctypes_object, **kwargs)
type_code = b'\t'
class pygridgain.datatypes.standard.StringArray

Bases: StandardArray

Array of Pascal-like strings. Payload-only, i.e. no type_code field in binary representation.

List(str) in Python.

standard_type

alias of String

class pygridgain.datatypes.standard.StringArrayObject

Bases: StandardArrayObject

List of strings.

type_code = b'\x14'
class pygridgain.datatypes.standard.TimeArray

Bases: StandardArray

standard_type

alias of TimeObject

class pygridgain.datatypes.standard.TimeArrayObject

Bases: StandardArrayObject

List of datetime.timedelta type values.

standard_type

alias of TimeObject

type_code = b'%'
class pygridgain.datatypes.standard.TimeObject

Bases: StandardObject

Time of the day as a number of milliseconds since midnight.

Represented as a datetime.timedelta in Python.

classmethod build_c_type()
default = datetime.timedelta(0)
classmethod from_python_not_null(stream, value: timedelta, **kwargs)
classmethod hashcode(value: timedelta, **kwargs) → int
pythonic

alias of timedelta

classmethod to_python_not_null(ctypes_object, **kwargs)
type_code = b'$'
class pygridgain.datatypes.standard.TimestampArray

Bases: StandardArray

standard_type

alias of TimestampObject

class pygridgain.datatypes.standard.TimestampArrayObject

Bases: StandardArrayObject

Translated into Python as a list of (datetime.datetime, integer) tuples.

standard_type

alias of TimestampObject

type_code = b'"'
class pygridgain.datatypes.standard.TimestampObject

Bases: StandardObject

A signed integer number of milliseconds past 1 Jan 1970, aka Epoch (8 bytes long integer), plus the delta in nanoseconds (4 byte integer, only 0..999 range used).

The accuracy is ridiculous. For instance, common HPETs have less than 10ms accuracy. Therefore no ns range calculations is made; epoch and fraction stored separately and represented as tuple(datetime.datetime, integer).

classmethod build_c_type()
default = (datetime.datetime(1970, 1, 1, 0, 0), 0)
classmethod from_python_not_null(stream, value: tuple, **kwargs)
classmethod hashcode(value: Tuple[datetime, int], **kwargs) → int

class pygridgain.datatypes.standard.UUIDArray

Bases: StandardArray

standard_type

alias of UUIDObject

class pygridgain.datatypes.standard.UUIDArrayObject

Bases: StandardArrayObject

Translated into Python as a list(uuid.UUID).

standard_type

alias of UUIDObject

type_code = b'\x15'
class pygridgain.datatypes.standard.UUIDObject

Bases: StandardObject

Universally unique identifier (UUID), aka Globally unique identifier (GUID). Payload takes up 16 bytes.

Byte order in to_python() and from_python() methods is changed for compatibility with java.util.UUID.

UUID_BYTE_ORDER = (7, 6, 5, 4, 3, 2, 1, 0, 15, 14, 13, 12, 11, 10, 9, 8)
classmethod build_c_type()

classmethod hashcode(value: UUID, **kwargs) → int

type_code = b'\n'
