pyignite.datatypes.complex module¶
-
class
pyignite.datatypes.complex.
Map
¶ Bases:
pyignite.datatypes.base.IgniteDataType
,pyignite.datatypes.complex._MapBase
Dictionary type, payload-only.
Ignite does not track the order of key-value pairs in its caches, hence the ordinary Python dict type, not the collections.OrderedDict.

ObjectArrayObject
¶ Bases:
pyignite.datatypes.null_object.Nullable
Array of Ignite objects of any consistent type. Its Python representation is tuple(type_id, iterable of any type). The only type ID that makes sense in Python client is
OBJECT
, that corresponds directly to the root object type in Java type hierarchy (java.lang.Object).-

CollectionObject
¶ Bases:
pyignite.datatypes.null_object.Nullable
Similar to object array, but contains platform-agnostic deserialization type hint instead of type ID.
Represented as tuple(hint, iterable of any type) in Python. Hints are:
USER_SET
− a set of unique Ignite thin data objects. The exact Java type of a set is undefined,USER_COL
− a collection of Ignite thin data objects. The exact Java type of a collection is undefined,ARR_LIST
− represents the java.util.ArrayList type,LINKED_LIST
− represents the java.util.LinkedList type,HashSet
type,LINKED_HASH_SET
− represents the java.util.LinkedHashSet type,SINGLETON_LIST
− represents the return type of the java.util.Collection.singletonList method.
It is safe to say that USER_SET (set in Python) and USER_COL (list) can cover all the imaginable use cases from Python perspective.

MapObject
¶ Bases:
pyignite.datatypes.null_object.Nullable
,pyignite.datatypes.complex._MapBase
This is a dictionary type.
Represented as tuple(type_id, value).
Type ID can be a
HASH_MAP
(corresponds to an ordinary dict in Python) or aLINKED_HASH_MAP
(collections.OrderedDict).-

WrappedDataObject
¶ Bases:
pyignite.datatypes.null_object.Nullable
One or more binary objects can be wrapped in an array. This allows reading, storing, passing and writing objects efficiently without understanding their contents, performing simple byte copy.
Python representation: tuple(payload: bytes, offset: integer). Offset points to the root object of the array.
