Syntax
public class SnapshotRows : TableRowsBase, INestedPersist, IEnumerable<INestedPersist>, ISoCollection, IList, ICollection, IEnumerable, 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 SnapshotRow to it, and use methods like to operate on the whole collection.
  • You can create a (nested) SnapshotRows SnapshotRows.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(SnapshotRows.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 SnapshotRow object directly, which has nested classes and GetFromIdx methods for each unique index. Similarly, there is a GetFromReader(SoDataReader, SnapshotTableInfo) 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 SnapshotRow given its index in the collection.

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

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

Methods

Add(SnapshotRow)

Add one SnapshotRow to the collection.

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

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

The index of the added SnapshotRow.

AddNew()

Add a new instance of SnapshotRow added to the collection.

Declaration
public SnapshotRow AddNew()
Returns
Type Description
SnapshotRow

A new instance of SnapshotRow added to the collection.

AddRange(IEnumerable<SnapshotRow>)

Add a range of SnapshotRow to the collection.

Declaration
public SnapshotRows AddRange(IEnumerable<SnapshotRow> rows)
Parameters
Type Name Description
IEnumerable<SnapshotRow> rows
Returns
Type Description
SnapshotRows

The updated SnapshotRows collection object.

CreateChild()

Create a new instance of SnapshotRow

Declaration
protected override TableRowBase CreateChild()
Returns
Type Description
TableRowBase

New instance of SnapshotRow
Overrides

CreateNew()

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

Declaration
public static SnapshotRows CreateNew()
Returns
Type Description
SnapshotRows

A new instance of the SnapshotRows object.

Find(Predicate<SnapshotRow>)

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

Declaration
public SnapshotRow Find(Predicate<SnapshotRow> condition)
Parameters
Type Name Description
Predicate<SnapshotRow> condition
Returns
Type Description
SnapshotRow

FindAll(Predicate<SnapshotRow>)

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

Declaration
public SnapshotRows FindAll(Predicate<SnapshotRow> condition)
Parameters
Type Name Description
Predicate<SnapshotRow> condition
Returns
Type Description
SnapshotRows

ForEach(Action<SnapshotRow>)

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

Declaration
public void ForEach(Action<SnapshotRow> whatToDo)
Parameters
Type Name Description
Action<SnapshotRow> whatToDo

GetFromCustomSearch(SnapshotRows.CustomSearch)

Create a new instance of the SnapshotRows 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 SnapshotRow objects representing each row will be returned.

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

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

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

GetFromReader(SoDataReader, SnapshotTableInfo)

Create a new instance of the SnapshotRows 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 SnapshotRow 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 SnapshotRows GetFromReader(SoDataReader reader, SnapshotTableInfo tableInfo)
Parameters
Type Name Description
SoDataReader reader

SoDataReader positioned to a valid database row.
SnapshotTableInfo tableInfo

SnapshotTableInfo 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
SnapshotRows

Remove(SnapshotRow)

Removes the given SnapshotRow from the collection

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

the SnapshotRow to be removed

ToArray()

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

ToString()

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

Declaration
public override string ToString()
Returns
Type Description
String
Overrides
