|
Create(bool)
Declaration
public static QueryableExecuter<T> Create(bool oDataQuery)
Parameters
| Type |
Name |
Description |
| bool |
oDataQuery |
Indicates if this queryableexecuter is being operated against an odata web service collection
of items or not
|
Returns
Create(Type, bool)
Creates a new QueryableExecuter<T, TT> with the TT type being specified from
inheritingTypeTT that must inherit/implement type T
Declaration
public static QueryableExecuter<T> Create(Type inheritingTypeTT, bool oDataQuery)
Parameters

| bool |
oDataQuery |
Indicates if this queryableexecuter is being operated against an odata web service collection
of items or not
|
Returns
CreateNewItem()
Returns a new instance of this inheriting type from QueryableExecuter. Used for
Clone() implementations to always return the correct new type as an exact copy
of the current one
