Description
Changes the role name of the active column or the specified column.
Constructor
As(String newRole) - Change the role name of the active column.
As(String original, String newRole) - Change the role name of the specified column.
Notes
Generally you have to feed rows to As directive from some other directive through a From directive. All this is best done using the as method present in every directive. Calling A.as("role") will change the active column role name of the results of A. This will resolve to new As("role").from(A) which resolves to new From(new As("role"),A)'. The as method can also be given two parameters corresponding to the As directive constructor with two parameters.
