Method Detail

setAttributeValue

public boolean setAttributeValue(AttributeContext ctx,
                                 java.lang.Object value)

This method is called by the data binding framework when a new value is to be set on an attribute in a bean. The attribute and bean are provided in the attribute context along with other framework context information.

Return true if the base framework should skip any further processing of this attribute set. Otherwise return false so that framework can perform a set or put of the attribute value based on introspection.

Specified by:

setAttributeValue in interface UpdateableDataControl

Overrides:

setAttributeValue in class UpdatableBeanDataControl

createRowData

public java.lang.Object createRowData(RowContext ctx)

This method is called by the data binding framework when a new row is needed from the data control.

Specified by:

createRowData in interface UpdateableDataControl

Overrides:

createRowData in class UpdatableBeanDataControl

Parameters:

ctx - Context of the new row.

Returns:

A data object for the new row.

registerDataProvider

public java.lang.Object registerDataProvider(RowContext ctx)

This method is called by the data binding facility before the row in the RowContext object is modified or marked as removed, so the row can be marked dirty by the data control.

Specified by:

registerDataProvider in interface UpdateableDataControl

Overrides:

registerDataProvider in class UpdatableBeanDataControl

Parameters:

ctx - Context of the row to be modified or removed.

Returns:

The data object that the row represents.

removeRowData

public boolean removeRowData(RowContext ctx)

This method is called by the data binding facility when a row should be removed from the underlying data source.

Specified by:

removeRowData in interface UpdateableDataControl

Overrides:

removeRowData in class UpdatableBeanDataControl

Parameters:

ctx - Context of the row to be removed.

Returns:

true if the operation is sucessful, false otherwise.

validate

public void validate()

Validates transaction if dirty.

Specified by:

validate in interface UpdateableDataControl

Overrides:

validate in class UpdatableBeanDataControl

release

public void release()

Releases the DataControl. The DataControl should be in a collectable state after release() has been invokd.

This should close all open DataControl resources.

Specified by:

release in interface DataControl

Overrides:
