Method Detail

getRowCount
public int getRowCount()
We don't know how many rows the result set has without scrolling through the whole thing.- Specified by:
getRowCountin classDataModel<Map<String,Object>>- Returns:
- the number of rows available.
-
getRowData
public Map<String,Object> getRowData()
Get the actual data of this row wrapped into a map. The specification is very strict about what has to be returned from here, so check the spec before modifying anything here.- Specified by:
getRowDatain classDataModel<Map<String,Object>>- Returns:
- The object associated with the current row index.
-
getRowIndex
public int getRowIndex()
Description copied from class:DataModelGet the current row index.- Specified by:
getRowIndexin classDataModel<Map<String,Object>>- Returns:
- The current row index.
-
getWrappedData
public Object getWrappedData()
Description copied from class:DataModelGet the entire collection of data associated with this component. Note that the actual type of the returned object depends upon the concrete subclass of DataModel; the object will represent an "ordered sequence of components", but may be implemented as an array, java.util.List, java.sql.ResultSet or other similar types.- Specified by:
getWrappedDatain classDataModel<Map<String,Object>>- Returns:
- the wrapped object.
-
isRowAvailable
public boolean isRowAvailable()
Description copied from class:DataModelReturns true if a call to getRowData will return a valid object.- Specified by:
isRowAvailablein classDataModel<Map<String,Object>>- Returns:
- true if a call to getRowData will return a valid object. false otherwise.
-
setRowIndex
public void setRowIndex(int rowIndex)
Description copied from class:DataModelSet the current row index. This affects the behaviour of the getRowData method in particular.- Specified by:
setRowIndexin classDataModel<Map<String,Object>>- Parameters:
rowIndex- The row index. It may be -1 to indicate "no row", or may be a value between 0 and getRowCount()-1.
-
setWrappedData
public void setWrappedData(Object data)
Description copied from class:DataModelSet the entire list of data associated with this component. Note that the actual type of the provided object must match the expectations of the concrete subclass of DataModel. See getWrappedData.- Specified by:
setWrappedDatain classDataModel<Map<String,Object>>- Parameters:
data- The object to be wrapped.
