Constructor Detail

AdapterDCService

public AdapterDCService(java.lang.String name,
                        java.lang.String def,
                        java.lang.Object dcInstance,
                        AbstractDefinition dcDef)

Creates a new AdapterDCService instance.

Parameters:

name - Name of the data control.

def - The location of the structure definition metadata.

dcInstance - the data control instance.

dcDef - the data control definition that has created this service.

Method Detail

fetchProviderProperty

protected java.lang.Object fetchProviderProperty(java.lang.String propName)

Fetches the data from the data control.

Overrides:

fetchProviderProperty in class DCBeanDataControl

invokeOperation

public boolean invokeOperation(java.util.Map bindingContext,
                               OperationBinding action)

Invokes the action associated with this data control. The WebService data control invokes the operation to return the data collection assoicated with the operation invocation.

Specified by:

invokeOperation in interface DataControl

Overrides:

invokeOperation in class DCBeanDataControl

Parameters:

bindingContext - A binding context that provide access to all binding related objects.

action - The action to be performed by the data control. For the Webservice data control, the action to be invoked is the webservice operation.

Returns:

true if this datacontrol has handled this action, false if the action should be interpreted in the bindings framework or in the caller.

hasOperationParamsChanged

public boolean hasOperationParamsChanged(OperationInfo operationInfo)

Check if the operation params has changed during an iterator execution. This method decides whether to call a method. If the parameter values are changed the method will be called again to get the result for the changed value. Otherwise it'll call the AbstractImpl (if implemented) to decide whether to call the method again.

Overrides:

hasOperationParamsChanged in class DCDataControl

Parameters:

operationInfo - The OperationInfo whose parameters need to evaluated to decide this params changed condition.

Returns:

true if the operation parameters have changed. Otherwise calls the impl to decide. If the impl is not available, i.e. the data control is not an AbstractImpl, it returns false.

applySortCriteria

protected void applySortCriteria(DCIteratorBinding iter,
                                 SortCriteria[] sortby)

Sets the sort critiera that will be applied next time when the source for this iteratorBinding is executed.

Overrides:

applySortCriteria in class DCBeanDataControl
