Class WrsModificationCallback

java.lang.Object

de.businesscode.bcdui.binding.write.WriteProcessingCallback

de.businesscode.bcdui.binding.write.WrsModificationCallback

Direct Known Subclasses:

WrsModificationLog

public class WrsModificationCallback
extends WriteProcessingCallback

preserves the update information on a record, takes following configuration parameters: the default values are marked with asterix (*), all parameters which have no default values are required.

bindingItemId

the binding item id this parameter is defined for

expression

the EL expression to be evaluated on the server, or constant string, allowing directives: ${} the bean in scope is named 'bcdBean'

ignore

never*: never ignores processing
update: processing ignored on wrs:M

isCoalesce

true*: the value written to database is evaluated from given expression on the server in following cases: either wrs:C for this bindingItemId is wrs:null OR this bindingItemId is entirely missing in processing WRS
false: always writes value from expression evaluated on the server, no matter whether it been sent along with WRS or not

Modifier and Type	Method	Description
void	endDataRow(WriteProcessingCallback.ROW_TYPE rowType, List<String> cValues, List<String> oValues)	ignores wrs:D if binding items are not located in WRS we augment it
void	endHeader(List<BindingItem> columns, List<Integer> columnTypes, Collection<String> keyColumnNames)	is called once WRS header has been read, the implementation may modify either data provided, at this point the serverSideValueBean and bindingSet are already initialized

WrsModificationCallback

public WrsModificationCallback()

Method Details

endHeader

public void endHeader(List<BindingItem> columns,
 List<Integer> columnTypes,
 Collection<String> keyColumnNames)

Description copied from class: WriteProcessingCallback

is called once WRS header has been read, the implementation may modify either data provided, at this point the serverSideValueBean and bindingSet are already initialized

Overrides:

endHeader in class WriteProcessingCallback

endDataRow

public void endDataRow(WriteProcessingCallback.ROW_TYPE rowType,
 List<String> cValues,
 List<String> oValues)

ignores wrs:D if binding items are not located in WRS we augment it

Overrides:

endDataRow in class WriteProcessingCallback

Parameters:

rowType - depending on the rowtype cValues and oValues change semantics, i.e: wrs:C in wrs:I vs wrs:C in wrs:M

cValues - list of values of wrs:C columns

oValues - list of values of wrs:O columns

evalValue

protected String evalValue(de.businesscode.bcdui.binding.write.BindingItemConfig item)

evaluates the value of given item

Parameters:

item -

Returns:

either a constant or evaluated expression

initialize

public void initialize()

Description copied from class: WriteProcessingCallback

perform initialization, read params, etc prior to call WriteProcessingCallback.endHeader(List, List, Collection) or WriteProcessingCallback.endDataRow(ROW_TYPE, List, List), at this point any other configurations members are already set

Overrides:

initialize in class WriteProcessingCallback

getBindingItemConfig

protected Set<de.businesscode.bcdui.binding.write.BindingItemConfig> getBindingItemConfig()

Returns:

the list of binding item config items
