Getting data from ADF bindings programmatically

These are some useful code snippets to work with ADF bindings programmatically:

// get the binding container  
BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();  
  
// get an ADF attributevalue from the ADF page definitions  
AttributeBinding attr = (AttributeBinding)bindings.getControlBinding("test");  
attr.setInputValue("test");  
  
// get an Action or MethodAction  
OperationBinding method = bindings.getOperationBinding("methodAction");  
method.execute();  
List errors = method.getErrors();  
  
method = bindings.getOperationBinding("methodAction");  
Map paramsMap = method.getParamsMap();  
paramsMap.put("param","value")  ;        
method.execute();  

// Get the data from an ADF tree or table  
DCBindingContainer dcBindings = 
        (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();  
  
FacesCtrlHierBinding treeData = (FacesCtrlHierBinding)bc.getControlBinding("tree");  
Row[] rows = treeData.getAllRowsInRange();  
  
// Get a attribute value of the current row of iterator  
DCIteratorBinding iterBind= (DCIteratorBinding)dcBindings.get("testIterator");  
String attribute = (String)iterBind.getCurrentRow().getAttribute("field1");  
  
// Get the error  
String error = iterBind.getError().getMessage();  

// refresh the iterator  
bindings.refreshControl();  
iterBind.executeQuery();  
iterBind.refresh(DCIteratorBinding.RANGESIZE_UNLIMITED);  
  
// Get all the rows of a iterator  
Row[] rows = iterBind.getAllRowsInRange();  
TestData dataRow = null;  
for (Row row : rows) {  
  dataRow = (TestData)((DCDataRow)row).getDataProvider();  
}  

// Get the current row of a iterator , a different way  
FacesContext ctx = FacesContext.getCurrentInstance();  
ExpressionFactory ef = ctx.getApplication().getExpressionFactory();  
ValueExpression ve = ef.createValueExpression(ctx.getELContext(), 
                "#{bindings.testIter.currentRow.dataProvider}", TestHead.class);  
TestHead test = (TestHead)ve.getValue(ctx.getELContext());  

 
// get the selected rows from a table component  
RowKeySet selection = resultTable.getSelectedRowKeys();  
Object[] keys = selection.toArray();  
List receivers = new ArrayList(keys.length);  
for ( Object key : keys ) {  
  User user = modelFriends.get((Integer)key);  
}  
  
// get  selected Rows of a table 2  
for (Object facesRowKey : table.getSelectedRowKeys()) {  
 table.setRowKey(facesRowKey);  
 Object o = table.getRowData();  
 JUCtrlHierNodeBinding rowData = (JUCtrlHierNodeBinding)o;  
 Row row = rowData.getRow();  
 Test testRow = (Test)((DCDataRow)row).getDataProvider() ;  
}
