public class JUCtrlRangeBinding

extends JUCtrlValueBinding

A JUControlBinding class responsible for binding controls/models that are bound to a range of Row objects in the BC4J layer. This class:

• Is responsible for updating the Control Bindings with attribute values from the BC4J Row objects for all attributes that this Control Binding is bound to by calling setValueAt() method for each attribute value with approprate row, column and value information.
• Declares (abstract) methods that all subclasses need to implement to handle Scroll and Navigation events from the BC4J RowIterator.

Constructor Detail

JUCtrlRangeBinding

public JUCtrlRangeBinding(java.lang.Object control,
                          DCIteratorBinding iterBinding,
                          java.lang.String[] attrNames)

This constructor passes on the control, iterator, and attribute binding information to its super.

Method Detail

getValueAt

public java.lang.Object getValueAt(int rowIndex,
                                   int attrIndex)

Returns the value as stored in the control at a given row and column index. This value is used by the binding to update attribute values in BC4J rows.

addControlToPanel

public void addControlToPanel(java.lang.Object panel,
                              java.lang.Object layoutObject,
                              java.lang.Object layoutCons)

Description copied from class: JUControlBinding

*** For internal framework use only ***

Specified by:

addControlToPanel in class JUControlBinding

setValueAt

public void setValueAt(java.lang.Object value,
                       int rowIndex,
                       int attrIndex)

getRangeStart

public int getRangeStart()

getRangeSize

public int getRangeSize()

getEstimatedRowCount

public long getEstimatedRowCount()

Returns the number of rows in the collection defined by the associated ViewObject's query (if this control is in data display mode). If this control is in find mode, returns the number of rows in the associated ViewCriteria object.

updateValuesFromRow

public void updateValuesFromRow(Row row)

This method is called in the framework when values of a single row need to be updated in a control (typically on a navigation event).

Overrides:

updateValuesFromRow in class JUCtrlValueBinding

getRangeSet

public java.util.List getRangeSet()

Returns a list of Map elements over the range of rows from the associated iterator binding. The elements in this list are wrapper objects over the indexed row in the range that restricts access to only the attributes that this control-binding is bound to. The map exposes the following properties for each row in the range:

index - returns Range Index of the row

key - returns Key of the row

keyStr - returns String format of the key of the row at this index()

currencyString - if this row is the current row, returns * else returns a space " ".

attributeValues - returns array of attribute values for attributes that are bound in this rangeBinding from the row

createValueBindingRef

protected JUCtrlValueBindingRef createValueBindingRef(JUCtrlRangeBinding rangeBinding,
                                                      int index,
                                                      Row row)

updateValuesFromRows

public void updateValuesFromRows(Row[] rows,
                                 boolean clear)

This method is invoked in the framework to update values displayed in the associated control. This implementation updates all values given in the array of rows irrespective of the clear flag (which indicates whether to clear out the existing displayed values or not).

Specified by:

updateValuesFromRows in class JUCtrlValueBinding

updateRangeScrolled

public void updateRangeScrolled(ScrollEvent event)

Method to handle scroll events from the BC4J iterator. Subclasses need to implement this method to update the currently displayed rowset (if desired).

Specified by:

updateRangeScrolled in class JUCtrlValueBinding

See Also:

ScrollEvent

updateNavigated

public void updateNavigated(NavigationEvent event)

Method to handle Navigation event from the BC4J iterator. Subclasses need to implement this method to update their current row display (if desired).

Specified by:

updateNavigated in class JUCtrlValueBinding

refreshControl

public void refreshControl()

*** For internal framework use only ***

Updates the values in a control that is bound using an Iterator already in use. (a valid row iterator) If you do not call this method, your control won't update unless you refresh the Iterator.

Specified by:

refreshControl in class DCControlBinding

resetInputState

protected void resetInputState()

Empty method to support DCControlBinding contract.

Overrides:

resetInputState in class JUCtrlValueBinding

internalGet

protected java.lang.Object internalGet(java.lang.String key)

Subclasses should override this to handle a specific key. If they do find the key valid, they should also set the mInternalGet_KeyResolved to 'true' so that bean-introspection is not done for valid null-value returns from the internalGet() call.

Properties returned vis getter on this control bindings are:

rangeSet - returns getRangeSet()

estimatedRowCount - returns getEstimatedRowCount()

Overrides:

internalGet in class JUCtrlValueBinding

release

protected void release(int flags)

Overrides:

release in class JUCtrlValueBinding

needsEstimatedRowCount

protected boolean needsEstimatedRowCount()

Overrides:

needsEstimatedRowCount in class DCControlBinding
