Method Detail
Top

ActivateRelationeSmartSecurityObjecteSmartSecurityObjectTokenRelation ()
Purpose: Activates the eSmartSecurityObjecteSmartSecurityObjectTokenRelation DATA-RELATION
Notes:

Top

AttachDataSources ()
Purpose: Attaches the DATA-SOURCE objects to the ProDataset Buffers
Notes: Overrides ABSTRACT method in Consultingwerk.OERA.DataAccess,
Invoked in FetchData and SaveChanges

Top

BindDataset (dataset)
Purpose: Do nothing, just receive the parameter and bind to the received
Dataset reference
Notes: Invoked from the class constructor

Parameters:
dsSecurityObject DATASET dsSecurityObject
DATASET to bind to
Top

DefineReadEvents ()
Purpose: TO-DO: Subscribe to ProDataset Event Handlers using SET-CALLBACK
as needed
Notes: Overrides ABSTRACT method in Consultingwerk.OERA.DataAccess,
Invoked in FetchData, note that the callback methods need to be
PUBLIC and need to have the Dataset defined as an INPUT Parameter.
Errors thrown from or raised in the FILL call-back methods of the
DataAccess class (SET-CALLBACK) will stop the Dataset from getting
filled / filled further. However errors thrown from the call-back
methods are not thrown from the FILL() method further up into a
catch block or to the client.
See http://knowledgebase.progress.com/articles/Article/P188375
Sample: BUFFER eCustomer:SET-CALLBACK (Consultingwerk.DatasetBufferCallbackEnum:AfterFill,
"eCustomerAfterFill":U) U) .

Top

DetachDataSources ()
Purpose: Detaches the DATA-SOURCE objects to the ProDataset Buffers
Notes: Overrides ABSTRACT method in Consultingwerk.OERA.DataAccess,
Invoked in FetchData and SaveChanges

Top

FetchData (IFetchDataRequest)
Purpose: Fetch data from the data source
Notes: poFetchDataRequest:Context property is used to control batching
(forward/backwards) and the FindRowWhere/PreFetchOnFind
The first entry by CHR(1) in the Context is CHR(2) delimited:
1. Entry: RESTART-ROWID(s) - CHR(5) Delimited
2. Entry: Find String
3. Entry: PrefetchOnFind Value
The poFetchDataRequest parameter may also be passed in as a
FetchDataAccessRequest instance allowing further specific arguments
to be passed that are only relevant to the DataAccess class

Parameters:
poFetchDataRequest Consultingwerk.OERA.IFetchDataRequest
The IFetchDataRequest object with the parameters for this call
Top

FetchDataByStaticQuery (IFetchDataByStaticQueryRequest)
Purpose: Fetches data for single table, using a static query
Notes:

Parameters:
poParameter Consultingwerk.OERA.IFetchDataByStaticQueryRequest
The query parameter object
Top

FetchSmartSecurityObjectBySecurityObjectGuid (character, character)
Purpose: FetchData method for static query
Notes:

Parameters:
pcSecurityObjectGuid CHARACTER
The SecurityObjectGuid value
pcChildTables CHARACTER
a list of the child tables to fill
Top

FetchSmartSecurityObjectBySecurityObjectName (character, character)
Purpose: FetchData method for static query
Notes:

Parameters:
pcSecurityObjectName CHARACTER
The SecurityObjectName value
pcChildTables CHARACTER
a list of the child tables to fill
Top

FilleSmartSecurityObjectTokenOfeSmartSecurityObject (character, character, logical)
Purpose: Fill child tables method for static query
Notes:

Parameters:
pcSecurityObjectGuid CHARACTER
The SecurityObjectGuid value
pcChildTables CHARACTER
The list of child table to fill
plApplyCallback LOGICAL
Whether to apply the buffer read callbacks
Top

SaveChanges ()
Purpose: Save changes to physical storage
Notes: This implementation of data access save traverses all records in order
to:
- Allow the DA to control transactions, which cannot be directly
controlled in distributed BL. Transaction control is a concern of
the BL, but should not be controlled with TRANSACTION keyword.
- Offer a course grained save interface from distributed BL
- The default operation here is just a transaction per record
- This simple sample does not use child relations to traverse
the buffers as the OERI BE example. (A property that controls
update order would give the same effect).
- Traversing of child data from a parent would make sense if done for
one parent record at a time.

CHARACTER SourceColumn (character, character)
Purpose: Returns the database field name matching a temp-table field name
contained in a consumers query string (query string vs. temp-table
definition)
Notes: Call-back used by Consultingwerk.OERA.Query.DSQueryString (part of
DataAccess:FetchData FetchData () query preparation
TO-DO: Provide code for alternative mapping

Parameters:
pcTable CHARACTER
The temp table name to return the source (database table) field name for
pcColumn CHARACTER
The temp table column name to return the source (database table) field name for
Returns CHARACTER
The database field name mapped to the passed in temp-table field
Top

CHARACTER SourceDefaultQuery (character)
Purpose: Returns the base query string used to retrieve data for the temp
tables. This query string will be appended by the query provided by
the consumer (FetchDataRequest object).
Notes: Call-back used by Consultingwerk.OERA.Query.DSQueryString (part of
DataAccess:FetchData FetchData () query preparation
TO-DO: Provide code to return the DATA-SOURCE root query string

Parameters:
pcTable CHARACTER
The temp table name to return the source default (database) query string for
Returns CHARACTER
The base query string used to retrieve data for the given temp-table

SecurityObjectDataAccess (handle)
Purpose: Constructor for the SecurityObjectDataAccess class
Notes: Used by the BusinessEntity, will receive the handle of the dataset
instance form the BusinessEntity as a parameter. Permanently BIND's
to that dataset using the PRIVATE BindDataset Method.

Parameters:
phDataset HANDLE
The handle of the Business Entity dataset
