Class SequenceRows

next_id to be used for each table Collection of SequenceRow. Each element of the collection represents one row in the Sequence table.

Syntax
public class SequenceRows : TableRowsBase, INestedPersist, IEnumerable<INestedPersist>, ISoCollection, IEnumerable, IList, ICollection, INotifyCollectionChanged, IBindingList
Remarks

Row collections can be created in several ways.

  • Use the static CreateNew() method to create a new, empty collection. You can then add objects of type SequenceRow to it, and use methods like to operate on the whole collection.
  • You can create a (nested) SequenceRows SequenceRows.CustomSearch object to obtain a query pre-populated with the correct tableinfo and return fields. This query can be modified with restrictions, etc. Then, use the static GetFromCustomSearch(SequenceRows.CustomSearch) method to apply the query to the database and obtain the result as a Rows object, with one item for each table row that matched your query.
  • For each non-unique index defined for the table, there is a corresponding GetFromIdx method to make retrieving data via the indexes easy.
Unique indexes are handled through the SequenceRow object directly, which has nested classes and GetFromIdx methods for each unique index. Similarly, there is a GetFromReader(SoDataReader, SequenceTableInfo) method to retrieve the results of queries that return more than one row (this method will iterate over the reader to fetch ALL results, so beware of fetching huge result sets).

Properties

Item[Int32]

Get a SequenceRow given its index in the collection.

Declaration
public SequenceRow this[int index] { get; }
Parameters
Type Name Description
System.Int32 index

Index of the SequenceRow in the collection
Property Value
Type Description
SequenceRow

Methods

Add(SequenceRow)

Add one SequenceRow to the collection.

Declaration
public int Add(SequenceRow row)
Parameters
Type Name Description
SequenceRow row

An instance of SequenceRow to be added to the collection.
Returns
Type Description
System.Int32

The index of the added SequenceRow.

AddNew()

Add a new instance of SequenceRow added to the collection.

Declaration
public SequenceRow AddNew()
Returns
Type Description
SequenceRow

A new instance of SequenceRow added to the collection.

AddRange(IEnumerable<SequenceRow>)

Add a range of SequenceRow to the collection.

Declaration
public SequenceRows AddRange(IEnumerable<SequenceRow> rows)
Parameters
Type Name Description
System.Collections.Generic.IEnumerable<SequenceRow> rows
Returns
Type Description
SequenceRows

The updated SequenceRows collection object.

CreateChild()

Create a new instance of SequenceRow

Declaration
protected override TableRowBase CreateChild()
Returns
Type Description
TableRowBase

New instance of SequenceRow
Overrides

CreateNew()

Create a new instance of the SequenceRows object. This collection will contain no rows.

Declaration
public static SequenceRows CreateNew()
Returns
Type Description
SequenceRows

A new instance of the SequenceRows object.

Find(Predicate<SequenceRow>)

Apply the predicate to each element of the collection and return the first row that matches; if no match then return null

Declaration
public SequenceRow Find(Predicate<SequenceRow> condition)
Parameters
Type Name Description
System.Predicate<SequenceRow> condition
Returns
Type Description
SequenceRow

FindAll(Predicate<SequenceRow>)

Return a new collection that contains only those elements that match the condition. Elements are shared, not clones! of the original collection

Declaration
public SequenceRows FindAll(Predicate<SequenceRow> condition)
Parameters
Type Name Description
System.Predicate<SequenceRow> condition
Returns
Type Description
SequenceRows

ForEach(Action<SequenceRow>)

Method that iterates over all members and applies the action parameter to each of them

Declaration
public void ForEach(Action<SequenceRow> whatToDo)
Parameters
Type Name Description
System.Action<SequenceRow> whatToDo

GetFromCustomSearch(SequenceRows.CustomSearch)

Create a new instance of the SequenceRows object, and populate it with data from a custom search. If the search returns no results, an empty collection will be returned; if the result contains rows, a collection of SequenceRow objects representing each row will be returned.

Declaration
public static SequenceRows GetFromCustomSearch(SequenceRows.CustomSearch query)
Parameters
Type Name Description
SequenceRows.CustomSearch query

The custom search to execute against the database
Returns
Type Description
SequenceRows

A new instance of the SequenceRows object, reflecting the result of the query.

GetFromReader(SoDataReader, SequenceTableInfo)

Create a new instance of the SequenceRows object, and populate it with data from a reader. If the search returns no results, an empty collection will be returned; if the result contains rows, a collection of SequenceRow objects representing each row will be returned.

Note that the internal logic starts by calling reader.Read(), which is correct if you hand the method the result of an ExecuteReader(), but if the reader has already been advanced one or more rows, the current row will be skipped and collection population will start with the next row.

Declaration
public static SequenceRows GetFromReader(SoDataReader reader, SequenceTableInfo tableInfo)
Parameters
Type Name Description
SoDataReader reader

SoDataReader positioned to a valid database row.
SequenceTableInfo tableInfo

SequenceTableInfo instance used in the query that is the source of the reader. The fields used from the reader will be those owned by this tableinfo object.
Returns
Type Description
SequenceRows

Remove(SequenceRow)

Removes the given SequenceRow from the collection

Declaration
public void Remove(SequenceRow row)
Parameters
Type Name Description
SequenceRow row

the SequenceRow to be removed

ToArray()

Declaration
public SequenceRow[] ToArray()
Returns
Type Description
SequenceRow[]

ToString()

For debugging: Number of members, and the first (up to) 5 items

Declaration
public override string ToString()
Returns
Type Description
System.String
