Abstract boundary condition class for finite difference problems. 
◆ Side
◆ applyBeforeApplying()
  
  | 
        
          | virtual void applyBeforeApplying | ( | operator_type & |  | ) | const |  | pure virtual | 
 
This method modifies an operator \( L \) before it is applied to an array \( u \) so that \( v = Lu \) will satisfy the given condition. 
Implemented in DirichletBC, and NeumannBC.
 
 
◆ applyAfterApplying()
  
  | 
        
          | virtual void applyAfterApplying | ( | array_type & |  | ) | const |  | pure virtual | 
 
This method modifies an array \( u \) so that it satisfies the given condition. 
 
 
◆ applyBeforeSolving()
  
  | 
        
          | virtual void applyBeforeSolving | ( | operator_type & | , |  
          |  |  | array_type & | rhs |  
          |  | ) |  | const |  | pure virtual | 
 
This method modifies an operator \( L \) before the linear system \( Lu' = u \) is solved so that \( u' \) will satisfy the given condition. 
 
 
◆ applyAfterSolving()
  
  | 
        
          | virtual void applyAfterSolving | ( | array_type & |  | ) | const |  | pure virtual | 
 
This method modifies an array \( u \) so that it satisfies the given condition. 
 
 
◆ setTime()
  
  | 
        
          | virtual void setTime | ( | Time | t | ) |  |  | pure virtual | 
 
This method sets the current time for time-dependent boundary conditions. 
Implemented in DirichletBC, and NeumannBC.
