Syntax

public static class LookupFilters

Methods

GetEntityFilter(IBaseEntity, IBaseEntity, IEntityRetriever, string)

Returns 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<IEnumerable<IBaseEntity>> GetEntityFilter(IBaseEntity currentItem, IBaseEntity parentItem, IEntityRetriever context, string searchText)

Parameters

Type	Name	Description
IBaseEntity	currentItem	The transaction to return valid entities for
IBaseEntity	parentItem	Any parent item associated with this transaction
IEntityRetriever	context	The current context this processor is running with
string	searchText	The name of the entity to filter on

Returns

Type	Description
Task<IEnumerable<IBaseEntity>>	A queryable filter for the entities that can be selected against the specified transaction currentItem

GetInstrumentFilter(IEntityRetriever, IBaseEntity, IBaseEntity, IReadOnlyCache)

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, IReadOnlyCache cache)

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
IReadOnlyCache	cache

Returns

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

GetOriginalEntityFilter(IBaseEntity, IBaseEntity, IEntityRetriever, string)

Declaration

public static Task<IEnumerable<IBaseEntity>> GetOriginalEntityFilter(IBaseEntity currentItem, IBaseEntity parentItem, IEntityRetriever context, string searchText)

Parameters

Type	Name	Description
IBaseEntity	currentItem
IBaseEntity	parentItem
IEntityRetriever	context
string	searchText

Returns

Type	Description
Task<IEnumerable<IBaseEntity>>

GetOriginalInstrumentFilter(IEntityRetriever, IBaseEntity, IBaseEntity)

Declaration

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

Parameters

Type	Name	Description
IEntityRetriever	retriever
IBaseEntity	currentItem
IBaseEntity	parentItem

Returns

Type	Description
Task<QueryableFilter>

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
Task<QueryableFilter>	A queryable filter for the paths that can be selected against the specified transaction currentItem
