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

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

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

Methods

Add(EjscriptRow)

Add one EjscriptRow to the collection.

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

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

The index of the added EjscriptRow.

AddNew()

Add a new instance of EjscriptRow added to the collection.

Declaration
public EjscriptRow AddNew()
Returns
Type Description
EjscriptRow

A new instance of EjscriptRow added to the collection.

AddRange(IEnumerable<EjscriptRow>)

Add a range of EjscriptRow to the collection.

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

The updated EjscriptRows collection object.

CreateChild()

Create a new instance of EjscriptRow

Declaration
protected override TableRowBase CreateChild()
Returns
Type Description
TableRowBase

New instance of EjscriptRow
Overrides

CreateNew()

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

Declaration
public static EjscriptRows CreateNew()
Returns
Type Description
EjscriptRows

A new instance of the EjscriptRows object.

Find(Predicate<EjscriptRow>)

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

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

FindAll(Predicate<EjscriptRow>)

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

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

ForEach(Action<EjscriptRow>)

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

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

GetFromCustomSearch(EjscriptRows.CustomSearch)

Create a new instance of the EjscriptRows 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 EjscriptRow objects representing each row will be returned.

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

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

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

GetFromIdxHierarchyId(Int32)

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

Declaration
public static EjscriptRows GetFromIdxHierarchyId(int hierarchyId)
Parameters
Type Name Description
System.Int32 hierarchyId
Returns
Type Description
EjscriptRows

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 Ejscript table. Non-unique indexes have corresponding inner classes and methods in the EjscriptRows collection, since they may return more than one row.

GetFromIdxIncludeId(String)

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

Declaration
public static EjscriptRows GetFromIdxIncludeId(string includeId)
Parameters
Type Name Description
System.String includeId
Returns
Type Description
EjscriptRows

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 Ejscript table. Non-unique indexes have corresponding inner classes and methods in the EjscriptRows collection, since they may return more than one row.

GetFromReader(SoDataReader, EjscriptTableInfo)

Create a new instance of the EjscriptRows 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 EjscriptRow 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 EjscriptRows GetFromReader(SoDataReader reader, EjscriptTableInfo tableInfo)
Parameters
Type Name Description
SoDataReader reader

SoDataReader positioned to a valid database row.
EjscriptTableInfo tableInfo

EjscriptTableInfo 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
EjscriptRows

Remove(EjscriptRow)

Removes the given EjscriptRow from the collection

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

the EjscriptRow to be removed

ToArray()

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

ToString()

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

Declaration
public override string ToString()
Returns
