ExtendedDataModel.getRowKey()

setRowKey

public void setRowKey(java.lang.Object key)

This method normally called by Visitor before request Data Row. (non-Javadoc)

Specified by:

setRowKey in class org.ajax4jsf.model.ExtendedDataModel

See Also:

ExtendedDataModel.setRowKey(java.lang.Object)

walk

public void walk(javax.faces.context.FacesContext context,
                 org.ajax4jsf.model.DataVisitor visitor,
                 org.ajax4jsf.model.Range range,
                 java.lang.Object argument)
          throws java.io.IOException

This is main part of Visitor pattern. Method called by framework many times during request processing. (non-Javadoc)

Specified by:

walk in class org.ajax4jsf.model.ExtendedDataModel

Throws:

java.io.IOException

See Also:

ExtendedDataModel.walk(javax.faces.context.FacesContext, org.ajax4jsf.model.DataVisitor, org.ajax4jsf.model.Range, java.lang.Object)

loadData

protected java.util.List<T> loadData(int startRow,
                                     int endRow)

Load range of data items from the source. Starting from startRow, and up to but excluding endRow

Parameters:

startRow -

endRow -

Returns:

list of ordered data

getRowCount

public int getRowCount()

Specified by:

getRowCount in class javax.faces.model.DataModel

getRowData

public T getRowData()

This is main way to obtain data row. It is intensively used by framework. We strongly recommend use of local cache in that method. (non-Javadoc)

Specified by:

getRowData in class javax.faces.model.DataModel

See Also:

DataModel.getRowData()

getKey

public java.lang.Object getKey(T o)

getObjectByKey

public T getObjectByKey(java.lang.Object key)

getRowIndex

public int getRowIndex()

Unused rudiment from old JSF staff. (non-Javadoc)

Specified by:

getRowIndex in class javax.faces.model.DataModel

See Also:

DataModel.getRowIndex()

setRowIndex

public void setRowIndex(int rowIndex)

Unused rudiment from old JSF staff. (non-Javadoc)

Specified by:

setRowIndex in class javax.faces.model.DataModel

See Also:

DataModel.setRowIndex(int)

getWrappedData

public java.lang.Object getWrappedData()

Unused rudiment from old JSF staff. (non-Javadoc)

Specified by:

getWrappedData in class javax.faces.model.DataModel

See Also:

DataModel.getWrappedData()

setWrappedData

public void setWrappedData(java.lang.Object data)

Unused rudiment from old JSF staff. (non-Javadoc)

Specified by:

setWrappedData in class javax.faces.model.DataModel

See Also:

DataModel.setWrappedData(java.lang.Object)

isRowAvailable

public boolean isRowAvailable()

Never called by framework. (non-Javadoc)

Specified by:

isRowAvailable in class javax.faces.model.DataModel

See Also:

DataModel.isRowAvailable()

getSerializableModel

public org.ajax4jsf.model.SerializableDataModel getSerializableModel(org.ajax4jsf.model.Range range)

This method suppose to produce SerializableDataModel that will be serialized into View State and used on a post-back. In current implementation we just mark current model as serialized. In more complicated cases we may need to transform data to actually serialized form.

Overrides:

getSerializableModel in class org.ajax4jsf.model.ExtendedDataModel

getDataProvider

public org.richfaces.model.DataProvider<T> getDataProvider()

setDataProvider

public void setDataProvider(org.richfaces.model.DataProvider<T> dataProvider)
