Patchset class abstract interface

A patchset obtained from a byte sequence or an active Session.

Unlike Changesets, patchsets don't store values for deletions (apart from the primary key) and don't keep original values for UPDATE records.

Implemented types

Constructors

Patchset.fromBytes(Uint8List bytes, CommonSqlite3 bindings)
Creates a patch set from the underlying serialized byte representation.
factory

Whether this collection has no elements.
no setterinherited
isNotEmpty → bool
Whether this collection has at least one element.
no setterinherited
iterator → ChangesetIterator

Methods

any(bool test(ChangesetOperation element)) → bool
Checks whether any element of this iterable satisfies test.
inherited
applyTo(CommonDatabase database, [ApplyChangesetOptions options = const ApplyChangesetOptions()]) → void
Applies this changeset or patchset to the database.
cast<R>() → Iterable<R>
A view of this iterable as an iterable of R instances.
inherited
contains(Object? element) → bool
Whether the collection contains an element equal to element.
inherited
elementAt(int index) → ChangesetOperation
Returns the indexth element.
inherited
every(bool test(ChangesetOperation element)) → bool
Checks whether every element of this iterable satisfies test.
inherited
expand<T>(Iterable<T> toElements(ChangesetOperation element)) → Iterable<T>
Expands each element of this Iterable into zero or more elements.
inherited
firstWhere(bool test(ChangesetOperation element), {ChangesetOperation orElse()?}) → ChangesetOperation
The first element that satisfies the given predicate test.
inherited
fold<T>(T initialValue, T combine(T previousValue, ChangesetOperation element)) → T
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
inherited
followedBy(Iterable<ChangesetOperation> other) → Iterable<ChangesetOperation>
Creates the lazy concatenation of this iterable and other.
inherited
forEach(void action(ChangesetOperation element)) → void
Invokes action on each element of this iterable in iteration order.
inherited
join([String separator = ""]) → String
Converts each element to a String and concatenates the strings.
inherited
lastWhere(bool test(ChangesetOperation element), {ChangesetOperation orElse()?}) → ChangesetOperation
The last element that satisfies the given predicate test.
inherited
map<T>(T toElement(ChangesetOperation e)) → Iterable<T>
The current elements of this iterable modified by toElement.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
reduce(ChangesetOperation combine(ChangesetOperation value, ChangesetOperation element)) → ChangesetOperation
Reduces a collection to a single value by iteratively combining elements of the collection using the provided function.
inherited
singleWhere(bool test(ChangesetOperation element), {ChangesetOperation orElse()?}) → ChangesetOperation
The single element that satisfies test.
inherited
skip(int count) → Iterable<ChangesetOperation>
Creates an Iterable that provides all but the first count elements.
inherited
skipWhile(bool test(ChangesetOperation value)) → Iterable<ChangesetOperation>
Creates an Iterable that skips leading elements while test is satisfied.
inherited
take(int count) → Iterable<ChangesetOperation>
Creates a lazy iterable of the count first elements of this iterable.
inherited
takeWhile(bool test(ChangesetOperation value)) → Iterable<ChangesetOperation>
Creates a lazy iterable of the leading elements satisfying test.
inherited
toList({bool growable = true}) → List<ChangesetOperation>
Creates a List containing the elements of this Iterable.
inherited
toSet() → Set<ChangesetOperation>
Creates a Set containing the same elements as this iterable.
inherited
toString() → String
A string representation of this object.
inherited
where(bool test(ChangesetOperation element)) → Iterable<ChangesetOperation>
Creates a new lazy Iterable with all elements that satisfy the predicate test.
inherited
whereType<T>() → Iterable<T>
Creates a new lazy Iterable with all elements that have type T.
