Base implementation for Query iterators.

Inheritance
object
QueryIteratorBase<T>
EntityIdIterator
Namespace: StylelabsStylelabs.MSdkStylelabs.M.Sdk.ModelsQuerying
Assembly: Stylelabs.M.Sdk.dll
Syntax
public abstract class QueryIteratorBase<T> : IQueryIterator<T>, IIterator where T : class, IQueryResult
Type Parameters
NameDescription
T

The type result returned by the iterator.

Constructors

QueryIteratorBase(Query, T)

Initializes a new instance of the QueryIteratorBase<T> class and continues iterating from the specified result on.

Declaration
protected QueryIteratorBase(Query query, T result)
Parameters
TypeNameDescription
Queryquery

The 'request' query.

Tresult

The result to start iterating from.

QueryIteratorBase(Query)

Initializes a new instance of the QueryIteratorBase<T> class.

Declaration
protected QueryIteratorBase(Query query)
Parameters
TypeNameDescription
Queryquery

The 'request' query.

Properties

Current

Gets get the current result during iteration.

Declaration
public T Current { get; }
Property Value
TypeDescription
T

Methods

CanMoveNext()

Checks if the iterator can move further through the results.

Declaration
public bool CanMoveNext()
Returns
TypeDescription
bool

true if there more results.

CanMovePrevious()

Checks if the iterator can move backwards through the results.

Declaration
public bool CanMovePrevious()
Returns
TypeDescription
bool

true if there move backwards.

GetResultAsync(Query)

Gets the results.

Declaration
protected abstract Task<T> GetResultAsync(Query query)
Parameters
TypeNameDescription
Queryquery

The 'request' query.

Returns
TypeDescription
Task<>

The query results.

MoveNextAsync()

Advances the enumerator to the next page/batch of the collection. The result will be available in Current.

Declaration
public Task<bool> MoveNextAsync()
Returns
TypeDescription
Task<>bool

true if the enumerator was successfully advanced to the next page; false if the enumerator has passed the end of the collection.

MovePreviousAsync()

Moves the enumerator backwards, to the previous page/batch of the collection. The result will be available in Current.

Declaration
public Task<bool> MovePreviousAsync()
Returns
TypeDescription
Task<>bool

true if the enumerator was successfully advanced to the previous page; false if the enumerator has passed the start of the collection.

Reset()

Resets the iterator to start before the first result again.

Declaration
public void Reset()

Explicit Interface Implementations

IIterator.Current

Gets the current result. This is initially null. Use MoveNextAsync() first.

Declaration
object IIterator.Current { get; }
Returns
TypeDescription
object
