Class AllocationPathProcessor

A processor for determining the Level each entity within a path sits at

Runs on saving changes to any IAllocationPathRule or IAllocationPath to ensure levels are always consistent and correct

Syntax

public class AllocationPathProcessor : IBaseDataSetProcessorWithDBSave, IBaseDataSetProcessor, IProcessor, IDisposable

Properties

Cache

A local cache for performance

Declaration

public IReadOnlyCache Cache { get; }

Property Value

Type	Description
IReadOnlyCache

IgnoreEvents

Indicates the processor should ignore changes to any items within the processor

Normally used when the processor responds to an event and wants to prevent any other responses while it finishes processing that change

Declaration

public bool IgnoreEvents { get; set; }

Property Value

Type	Description
System.Boolean

Loaded

Flag to indicate if the processor has been fully loaded

Declaration

public bool Loaded { get; }

Property Value

Type	Description
System.Boolean

Order

If we have multiple save processors working, this indicates the order in which they will be processed with relation to each other

Declaration

public short Order { get; }

Property Value

Type	Description
System.Int16

Reporter

A reporter to provide feedback to a log, or client depending on the context the process is running under

Declaration

public BusyProgressReporter Reporter { get; set; }

Property Value

Type	Description
BusyProgressReporter

SaveProcessed

Indicates the ProcessOnDBSave has already been run. This is set by the system during save, and prevents recursive calls.

It is also released by the system on save completion/failure

Declaration

public bool SaveProcessed { get; set; }

Property Value

Type	Description
System.Boolean

Updater

A context to ensure the process can query, load and modify all LemonEdge data

Declaration

public IEntityUpdater Updater { get; }

Property Value

Type	Description
IEntityUpdater

User

The current logged in user the process is running under

Declaration

public UserInfo User { get; }

Property Value

Type	Description
UserInfo

Methods

AddToDataSetToProcess(IBaseEntity, EntityOperation)

Adds the specified IAllocationPathRule or IAllocationPath to this processor

Declaration

public void AddToDataSetToProcess(IBaseEntity item, EntityOperation operationType)

Parameters

Type	Name	Description
IBaseEntity	item	THe IAllocationPathRule or IAllocationPath to add that is a part of this processor
EntityOperation	operationType	The type of modification this item has

Dispose()

Declaration

public void Dispose()

Dispose(Boolean)

Declaration

protected virtual void Dispose(bool disposing)

Parameters

Type	Name	Description
System.Boolean	disposing

GetAllowableEntityIDsInPath()

Returns a list of the valid ids for entities within the EntitySetID that can be added to this allocation path

Declaration

public Task<IEnumerable<Guid>> GetAllowableEntityIDsInPath()

Returns

Type	Description
System.Threading.Tasks.Task<System.Collections.Generic.IEnumerable<System.Guid>>	A task with a list of the valid ids for entities within the EntitySetID that can be added to this allocation path

IsChangedItemPartOfDataSet(IBaseEntity)

Returns true for a IAllocationPathRule or IAllocationPath that is part of the path this processor handles

Declaration

public bool IsChangedItemPartOfDataSet(IBaseEntity item)

Parameters

Type	Name	Description
IBaseEntity	item	The item to see if it belongs in this processor

Returns

Type	Description
System.Boolean	True for a IAllocationPathRule or IAllocationPath that is part of the path this processor handles

Load()

A thread safe implementation to load all required data for the processor

Once completed Loaded should return true.

Declaration

public Task Load()

Returns

Type	Description
System.Threading.Tasks.Task	A task indicating the completion of the load operation

OnPathEntitySetChanged()

Indicates the allocation path rules have changed and the processor needs to reload all the entities within the path

Declaration

public void OnPathEntitySetChanged()

ProcessOnDBSave()

Calculates the correct level (Level) for each entity in the path

Declaration

public Task ProcessOnDBSave()

Returns

Type	Description
System.Threading.Tasks.Task	A task indicating the completion of the operation

RollbackChanges()

Changes are valid within the context anyway and do not need to be rolled back on failure

Declaration

public Task RollbackChanges()

Returns

Type	Description
System.Threading.Tasks.Task	A task indicating the completion of the operation

UpdateLevels()

Updates all the Level values for the entities in the path to correctly reflect their order through the path

Declaration

public Task UpdateLevels()

Returns

Type	Description
System.Threading.Tasks.Task	A task indicating the completion of the operation

Validate()

Any changes are valid within the context anyway

Declaration

public Task Validate()

Returns

Type	Description
System.Threading.Tasks.Task	A task indicating the completion of the operation
