Class ArchiveProviderFactory

This is the class factory for Archive Providers. It uses the SuperOffice.Factory.PluginFactory class together with the ArchiveProviderAttribute to identify classes that implement the IArchiveProvider interface. These are ordered by priority, the lowest value wins for any particular provider name. The system-standard providers all have priority int.MaxValue/2 so they are in the middle of the possible range.

Constructors

ArchiveProviderFactory()

This is the class factory for Archive Providers. It uses the SuperOffice.Factory.PluginFactory class together with the ArchiveProviderAttribute to identify classes that implement the IArchiveProvider interface. These are ordered by priority, the lowest value wins for any particular provider name. The system-standard providers all have priority int.MaxValue/2 so they are in the middle of the possible range.

Declaration

public ArchiveProviderFactory()

Fields

DefaultPageSize

This is the class factory for Archive Providers. It uses the SuperOffice.Factory.PluginFactory class together with the ArchiveProviderAttribute to identify classes that implement the IArchiveProvider interface. These are ordered by priority, the lowest value wins for any particular provider name. The system-standard providers all have priority int.MaxValue/2 so they are in the middle of the possible range.

Declaration

public const int DefaultPageSize = 50

Field Value

Type	Description
int

Properties

KnownArchiveProviders

Returns an array of information about all known archive providers. This array reflects the state after prioritization and duplicate elimination, so that only 'surviving' providers are present.

Declaration

public static PluginInfo[] KnownArchiveProviders { get; }

Property Value

Type	Description
PluginInfo[]

Methods

AddExtendersToProvider(IArchiveProviderExtensible)

Scans the available plugins to determine if there exist extenders to the given provider, and instantiates and links up each such extender.

Declaration

public static void AddExtendersToProvider(IArchiveProviderExtensible provider)

Parameters

Type	Name	Description
IArchiveProviderExtensible	provider	Extensible provider (parent)

Remarks

The parent provider (target) for the extension is identified through the provider name declared by its ArchiveProvider attribute. If the target has no such attribute, then the unqualified class name is used instead. The fallback for missing attribute is not likely to be used as long as this method is called from within the Provider factory.

AddExtensionsToProvider(IArchiveProvider)

Given a provider, use reflection to discover subproviders and extensions, and instantiate & wire-up any such

Declaration

public static void AddExtensionsToProvider(IArchiveProvider result)

Parameters

Type	Name	Description
IArchiveProvider	result

AddSubQueriesToMultiProvider(IArchiveMultiQueryProvider)

Scans the available plugins to determine if there exist subproviders intended for the given multi query provider, and instantiates and links up any such subproviders.

Declaration

public static void AddSubQueriesToMultiProvider(IArchiveMultiQueryProvider provider)

Parameters

Type	Name	Description
IArchiveMultiQueryProvider	provider	Multi query provider (parent)

Remarks

The parent provider (target) for the extension is identified through the provider name declared by its ArchiveProvider attribute. If the target has no such attribute, then the unqualified class name is used instead. The fallback for missing attribute is not likely to be used as long as this method is called from within the Provider factory.

Create(string)

Create a provider for the given provider name, and hook up any plugins registered for it.

Declaration

public static IArchiveProvider Create(string providerName)

Parameters

Type	Name	Description
string	providerName	Name of provider. Possibly including a string parameter, like name:parameter

Returns

Type	Description
IArchiveProvider	Provider class, if at least one provider has registered for the name

Remarks

Providers can be extended - subqueries added to multiqueryproviders, and extensions added to normal query providers. The hookup is done by the factory, not by each individual provider.

Create(string, string)

This is the class factory for Archive Providers. It uses the SuperOffice.Factory.PluginFactory class together with the ArchiveProviderAttribute to identify classes that implement the IArchiveProvider interface. These are ordered by priority, the lowest value wins for any particular provider name. The system-standard providers all have priority int.MaxValue/2 so they are in the middle of the possible range.

Declaration

public static IArchiveProvider Create(string providerName, string context)

Parameters

Type	Name	Description
string	providerName
string	context

Returns

Type	Description
IArchiveProvider

Create(string, string, bool)

Create a provider for the given provider name, and hook up any plugins registered for it.

Declaration

public static IArchiveProvider Create(string providerName, string context, bool blockAggregationWrapper)

Parameters

Type	Name	Description
string	providerName	Name of provider. Possibly including a string parameter, like name:parameter
string	context	Contextual information to pass on to providers' constructor; non-blank/non-null values require the provider to have a public constructor taking the actual parameter type as its only parameter. null here means 'call the default (parameter-less) constructor', not 'call constructor with parameter value null!'
bool	blockAggregationWrapper	If true, then the AggregationProvider will not be hooked up. Use sparingly in cases where you really need to avoid this happening, and you can't mark the provider itself with the NoAggregationAttribute

Returns

Type	Description
IArchiveProvider	Provider class, if at least one provider has registered for the name

Remarks

Providers can be extended - subqueries added to multiqueryproviders, and extensions added to normal query providers. The hookup is done by the factory, not by each individual provider.

An additional hookup is performed to add the AggregationProvider, to enable the aggregation functions. Archive providers can opt out by adding the NoAggregationAttribute to their declaration.

The CreateArchiveProvider timer records timings of the separate parts.

Flush()

Reset all cached data - plugins created by factory, stock providers and cached column infos

Declaration

public static void Flush()

GetActualProvider(Type)

Determine the actual provider to create, given a known provider

Declaration

public static Type GetActualProvider(Type internalProvider)

Parameters

Type	Name	Description
Type	internalProvider	The original provider, usually something created by SuperOffice

Returns

Type	Description
Type	The current provider class that fulfills this role. If the original type does not exist, does not have a valid attribute or does not have an implementation, the original, incoming type is returned.

Remarks

Some internal multi-query providers hard-code what inner providers should be used. In this case it may still be useful to be able to override the standard providers with partner-defined ones. This method will extract the provider name attribute from the original provider, and determine what actual type corresponds to this name - taking any overrides into account.

GetAvailableColumns(string, string)

Get the available column list for the given provider. This method provides FAST, CACHED access to the column list, which is an order of magnitude faster than instantiating the provider just to get the same list.

Declaration

public static List<ArchiveColumnInfo> GetAvailableColumns(string providerName, string context = "")

Parameters

Type	Name	Description
string	providerName	Case-insensitive name of provider
string	context

Returns

Type	Description
List<ArchiveColumnInfo>	List of available columns; the column objects are clones and may be mistreated in any way you desire :-)

GetAvailableEntities(string, string)

Get the available entity list for the given provider. This method provides FAST, CACHED access to the entity list, which is an order of magnitude faster than instantiating the provider just to get the same list.

Declaration

public static List<ArchiveRowTypeInfo> GetAvailableEntities(string providerName, string context = "")

Parameters

Type	Name	Description
string	providerName	Case-insensitive name of provider
string	context

Returns

Type	Description
List<ArchiveRowTypeInfo>	List of available entities; the entity objects are clones and may be mistreated in any way you desire :-)

HandlesCustomObject(string, string)

This is the class factory for Archive Providers. It uses the SuperOffice.Factory.PluginFactory class together with the ArchiveProviderAttribute to identify classes that implement the IArchiveProvider interface. These are ordered by priority, the lowest value wins for any particular provider name. The system-standard providers all have priority int.MaxValue/2 so they are in the middle of the possible range.

Declaration

public static bool HandlesCustomObject(string providerName, string context = "")

Parameters

Type	Name	Description
string	providerName
string	context

Returns

Type	Description
bool
