getDefaultBeanClassName

public java.lang.String getDefaultBeanClassName()

Description copied from class: InstantiateBeanAction

Returns the default TableBean class name that should be used unless another class name was explicitly defined in the request.

Specified by:

getDefaultBeanClassName in class InstantiateBeanAction

Returns:

Returns the default TableBean class name.

getRequiredBeanClassName

public java.lang.String getRequiredBeanClassName()

Description copied from class: InstantiateBeanAction

Returns the reqired TableBean class name. If a custom class name was explicitly defined in the request that class has to be assignable to the class returned by this method.

Specified by:

getRequiredBeanClassName in class InstantiateBeanAction

Returns:

Returns the required TableBean class name.

getAlwaysInstantiate

public boolean getAlwaysInstantiate()

Description copied from class: InstantiateBeanAction

Returns whether to always instantiate a TableBean when this action executes. If not, any existing TableBean that was found will be reused.

Specified by:

getAlwaysInstantiate in class InstantiateBeanAction

Returns:

Returns whether to always instantiate.
