Direct Known Subclasses:

JUIteratorBinding

public abstract class DCIteratorBinding

extends java.lang.Object

implements RowSetListener, RowSetManagementListener

DCIteratorBinding is the binding class that interacts with RowIterator objects to iterate over rows and provide the current row(s) for use in a client application or to view via various control bindings. DCIteratorBinding objects are uniquely identified by name in a DCBindingContainer which acts as a container of iterator bindings. This class handles the events generated from the associated RowIterator and sends the current Row (rows in range) over to individual control bindings to display current data. This class also manages the findMode data for the associated iterator and ViewObject(incase of BC4J).

At runtime, an application can bind an instance of oracle.jbo.NavigatableRowIterator to a DCIteratorBinding object using the bindRowSetIterator method.

Method Detail

setDef

protected void setDef(DCIteratorBindingDef def)

Internal: Applications should not use this method. After creation sets the def used to create this iterator binding.

getDef

public DCIteratorBindingDef getDef()

Internal: Applications should not use this method.

prepareForInput

public void prepareForInput()

Internal: Applications should not use this method. Called on this binding before a binding returns from processInputValue This gives the iterator binding a chance to mark new row state to STATUS_NEW from initialized and hence submit the new row even if there are no changes on the row.

isAccessorIterator

public boolean isAccessorIterator()

Is this bound to a collection returned from a bean accessor?

getName

public final java.lang.String getName()

Returns the name of this iterator binding. Iterator Binding objects are uniquely identified by name in a DCBindingContainer.

getDisplayName

public final java.lang.String getDisplayName()

Returns the name of this IteratorBinding.

setName

public void setName(java.lang.String name)

Internal: Applications should not use this method.

getVOName

public java.lang.String getVOName()

Internal: Applications should not use this method. Returns the name of the ViewObject instance of the iterator to which this iterator binding is associated.

getSourceName

public java.lang.String getSourceName()

Returns the name of the collection instance to which this iterator binding is bound to.

getViewDefName

public final java.lang.String getViewDefName()

Internal: Applications should not use this method. Returns the name of the ViewDefinition object.

reportException

public void reportException(boolean markDead,
                            java.lang.Exception ex)

Utility method to report exceptions via the containing binding container. If the exception is not JboException, this method creates a JboException that contains the input exception object and passes only JboException to the bindingcontainer. If BindingContainer is null then this method rethrows the JboException.

Parameters:

markDead - if this iterator binding should be marked as not alive for any further usage.

ex - Exception object to be reported via the BindingContainer.

bindRowSetIterator

public void bindRowSetIterator(NavigatableRowIterator iter,
                               boolean initRangeSize)

Use this method to bind a new instance of RowIterator from a Business Service to this binding. This method should be used to display data from a different RowIterator of the same Collection type in a given form. For example, if a tree is used to navigate Departments and their employees, upon selecting an employee node, an application can pass the Employee node's RowIterator over to this iterator binding, to update the display in another panel of Employee data with the currently selected Employee.

This method will not directly update the control-bindings for non-ADFJClient apps. The caller can optionally call navigated(null) method, with null for the Event parameter to notify each control bound to this iterator binding to update it's displayed value with the new iterator's current row.

Parameters:

iter - RowIterator instance from which to display data in bound controls.

initRangeSize - determines whether this iterator's range size should be adjusted to this binding's range size. This should be used to extend the range size from the default in the RowIterator to whatever is required by this iterator binding. For example, if a RowIterator whose range size is 1 is passed to this method and a grid control is bound to this iterator binding, then the grid may need more than one row to display from the current range. So, this flag should be true in that case to allow the grid to get the full range of rows to display, rather than updating its display one row at a time.

setIteratorMadeVisible

protected void setIteratorMadeVisible(boolean flag)

isRowSetEventsEnabled

public final boolean isRowSetEventsEnabled()

Returns true if this IteratorBinding should notify the containing BindingContainer's RowSetListeners of RowSet events.

public final void setRowSetEventsEnabled(boolean flag)

Set this flag if this IteratorBinding should pass on the rowset events to containing BindingContainer's RowSetListeners. Applications should turn off this flag for IteratorBindings used for readonly purposes like LOVs, etc which do not need any UI overrides like enabling/disabling a control etc.

suspendRowSetEventsHandling

public void suspendRowSetEventsHandling(boolean flag)

Set this flag to turn off reacting to RowSetIterator events. BindingContainer uses this during refreshControl() during batch datacontrol operations. Also when this iterator is released the events-handling may be turned off by using this suspend.

Returns true if this IteratorBinding is not reacting to any RowSetIterator events.
