Constructor Detail

DataSourceDataRows

public DataSourceDataRows()

Method Detail

createRowsFromDataSouce

protected void createRowsFromDataSouce()

Retrive the rows object by invoking the service method on the data source.

getObject

public java.lang.Object getObject()

Description copied from interface: IBoundObject

Get the bound object. Depending on the implementation this may be the same as the sourceObject.

Specified by:

getObject in interface IBoundObject

Overrides:

getObject in class ObjectReference

Returns:

resolved object reference.

setSourceObject

public void setSourceObject(java.lang.Object rows)

Description copied from interface: IBoundObject

Set the source object that will be used as a reference for the bound object.

Specified by:

setSourceObject in interface IBoundObject

Overrides:

setSourceObject in class ObjectReference

Parameters:

rows - the source object

setServiceSignature

public void setServiceSignature(java.lang.String service)

Description copied from interface: IDataSourceService

This is the service method signature that is to be use. It has to be complete including parameter types e.g. getUserRecord(Integer id);

Specified by:

setServiceSignature in interface IDataSourceService

Parameters:

service - signature

getServiceSignature

public java.lang.String getServiceSignature()

Description copied from interface: IDataSourceService

Get the service signature for this action.

Specified by:

getServiceSignature in interface IDataSourceService

Returns:

service signature

setServiceArgument

public void setServiceArgument(ObjectReference arg)

Description copied from interface: IDataSourceService

Set the argument for the service call, according to the method signature set with the setService method.

Specified by:

setServiceArgument in interface IDataSourceService

Parameters:

arg - the service argument

getServiceArgument

public ObjectReference getServiceArgument()

Description copied from interface: IDataSourceService

Get the argument used as the parameter for the service call.

Specified by:

getServiceArgument in interface IDataSourceService

Returns:

argument used for the service

refresh

public void refresh()

Description copied from interface: IBoundObject

Refresh the referenced object. A call to this method denotes to the reference object that any cached information should be discarted, or that the referenced object has changed. If the referenced object is dynamic (such as the result of a method invocation) the object will be refreshed.

Specified by:

refresh in interface IBoundObject

Overrides:

refresh in class ObjectReference

get

public java.lang.Object get(int index)

Description copied from interface: IRowsDataObject

Retrieve the value of the row at the given index.

Specified by:

get in interface IRowsDataObject

Parameters:

index - index of the row to retrieve

set

public void set(int index,
                java.lang.Object value)

Description copied from interface: IRowsDataObject

Set the value at the given index

Specified by:

set in interface IRowsDataObject

Parameters:

index - the index to set

value - the new value

actionPerformed

public void actionPerformed(IActionBinder action)

Description copied from interface: IBoundObject

Notify the bound object that an action was performed where the reference object was used to perform an action. Typically a binder can choose the manner of reaction, if any.

Specified by:

actionPerformed in interface IBoundObject

Overrides:

actionPerformed in class ObjectReference

Parameters:

action - the action that has occurred.
