Syntax
public class SAttachmentRows : 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 SAttachmentRow to it, and use methods like to operate on the whole collection.
  • You can create a (nested) SAttachmentRows SAttachmentRows.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(SAttachmentRows.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 SAttachmentRow object directly, which has nested classes and GetFromIdx methods for each unique index. Similarly, there is a GetFromReader(SoDataReader, SAttachmentTableInfo) 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 SAttachmentRow given its index in the collection.

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

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

Methods

Add(SAttachmentRow)

Add one SAttachmentRow to the collection.

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

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

The index of the added SAttachmentRow.

AddNew()

Add a new instance of SAttachmentRow added to the collection.

Declaration
public SAttachmentRow AddNew()
Returns
Type Description
SAttachmentRow

A new instance of SAttachmentRow added to the collection.

AddRange(IEnumerable<SAttachmentRow>)

Add a range of SAttachmentRow to the collection.

Declaration
public SAttachmentRows AddRange(IEnumerable<SAttachmentRow> rows)
Parameters
Type Name Description
IEnumerable<SAttachmentRow> rows
Returns
Type Description
SAttachmentRows

The updated SAttachmentRows collection object.

CreateChild()

Create a new instance of SAttachmentRow

Declaration
protected override TableRowBase CreateChild()
Returns
Type Description
TableRowBase

New instance of SAttachmentRow
Overrides

CreateNew()

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

Declaration
public static SAttachmentRows CreateNew()
Returns
Type Description
SAttachmentRows

A new instance of the SAttachmentRows object.

Find(Predicate<SAttachmentRow>)

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

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

FindAll(Predicate<SAttachmentRow>)

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

Declaration
public SAttachmentRows FindAll(Predicate<SAttachmentRow> condition)
Parameters
Type Name Description
Predicate<SAttachmentRow> condition
Returns
Type Description
SAttachmentRows

ForEach(Action<SAttachmentRow>)

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

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

GetFromCustomSearch(SAttachmentRows.CustomSearch)

Create a new instance of the SAttachmentRows 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 SAttachmentRow objects representing each row will be returned.

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

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

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

GetFromIdxAttachmentId(Int32)

Create a new instance of the SAttachmentRow object, by querying the database table via the index 'IDXS_attachmentAttachment_id'. This method is intended to make it easy to use efficient queries that match a database index.

Declaration
public static SAttachmentRows GetFromIdxAttachmentId(int attachmentId)
Parameters
Type Name Description
Int32 attachmentId
Returns
Type Description
SAttachmentRows

Row object that represents the result of the search. will be true if the query did not match any row in the table
Remarks

This method represents one of the unique indexes on the SAttachment table. Non-unique indexes have corresponding inner classes and methods in the SAttachmentRows collection, since they may return more than one row.

GetFromIdxMessageId(Int32)

Create a new instance of the SAttachmentRow object, by querying the database table via the index 'IDXS_attachmentMessage_id'. This method is intended to make it easy to use efficient queries that match a database index.

Declaration
public static SAttachmentRows GetFromIdxMessageId(int messageId)
Parameters
Type Name Description
Int32 messageId
Returns
Type Description
SAttachmentRows

Row object that represents the result of the search. will be true if the query did not match any row in the table
Remarks

This method represents one of the unique indexes on the SAttachment table. Non-unique indexes have corresponding inner classes and methods in the SAttachmentRows collection, since they may return more than one row.

GetFromReader(SoDataReader, SAttachmentTableInfo)

Create a new instance of the SAttachmentRows 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 SAttachmentRow 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 SAttachmentRows GetFromReader(SoDataReader reader, SAttachmentTableInfo tableInfo)
Parameters
Type Name Description
SoDataReader reader

SoDataReader positioned to a valid database row.
SAttachmentTableInfo tableInfo

SAttachmentTableInfo 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
SAttachmentRows

Remove(SAttachmentRow)

Removes the given SAttachmentRow from the collection

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

the SAttachmentRow to be removed

ToArray()

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

ToString()

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

Declaration
public override string ToString()
Returns
Type Description
String
