Syntax

public static class LookupFilters

Methods

GetEntityFilter(IEntityRetriever, IReadOnlyCache, IBaseEntity, IBaseEntity)

Returns a queryable filter for the entities that can be selected against the specified transaction currentItem

If the transaction is against an instrument, only the OwningEntityID is allowed, else the entities in the path of the transaction are allowed

Declaration

public static Task<QueryableFilter> GetEntityFilter(this IEntityRetriever retriever, IReadOnlyCache cache, IBaseEntity currentItem, IBaseEntity parentItem)

Parameters

Type	Name	Description
IEntityRetriever	retriever	The current context this processor is running with
IReadOnlyCache	cache	The current local cache
IBaseEntity	currentItem	The transaction to return valid entities for
IBaseEntity	parentItem	Any parent item associated with this transaction

Returns

Type	Description
System.Threading.Tasks.Task<QueryableFilter>	A queryable filter for the entities that can be selected against the specified transaction currentItem

GetInstrumentFilter(IEntityRetriever, IBaseEntity, IBaseEntity)

Returns a queryable filter for the instruments that can be selected against the specified transaction currentItem

If the transaction is against an entity, only allow instruments that have it as their OwningEntityID,

else if against a path only allow instruments that have their OwningEntityID as an entity in the path

Declaration

public static Task<QueryableFilter> GetInstrumentFilter(this IEntityRetriever retriever, IBaseEntity currentItem, IBaseEntity parentItem)

Parameters

Type	Name	Description
IEntityRetriever	retriever	The current context this processor is running with
IBaseEntity	currentItem	The transaction to return valid instruments for
IBaseEntity	parentItem	Any parent item associated with this transaction

Returns

Type	Description
System.Threading.Tasks.Task<QueryableFilter>	A queryable filter for the instruments that can be selected against the specified transaction currentItem

GetPathFilter(IEntityRetriever, IBaseEntity, IBaseEntity)

Returns a queryable filter for the paths that can be selected against the specified transaction currentItem

If the transaction is against an entity, only allow paths that contain rules against that entity,

Declaration

public static Task<QueryableFilter> GetPathFilter(this IEntityRetriever retriever, IBaseEntity currentItem, IBaseEntity parentItem)

Parameters

Type	Name	Description
IEntityRetriever	retriever	The current context this processor is running with
IBaseEntity	currentItem	The transaction to return valid paths for
IBaseEntity	parentItem	Any parent item associated with this transaction

Returns

Type	Description
System.Threading.Tasks.Task<QueryableFilter>	A queryable filter for the paths that can be selected against the specified transaction currentItem
