solvers.linearSystem.btf.topLevelBlocks.B2Block

public class B2Block
extends TopLevelBlock

This class implements the B2 Block of the B matrix. The Factory Methods newMacroBlock and subBlockCopy are implemented to return the correct block type in the parallel hierarchy. Type 1 Macro Blocks are selected for lower class linear systems

Description copied from class: TopLevelBlock

Factory Method for sub-block creation This method is to be overridden by subclasses to instantiate a copy of the current block of correct type

Specified by:

subBlockCopy in class TopLevelBlock

Parameters:

current_class - The class for which the copy is created

Returns:

A shallow copy of calling block, for the current_class. Without macro blocks.

Throws:

BTFMatrixErrorException

InternalErrorException

InconsistentLinearSystemException

newMacroBlock

protected MacroBlock newMacroBlock(Position block_position,
 int h)
                            throws InternalErrorException,
InconsistentLinearSystemException

Description copied from class: TopLevelBlock

Factory Method for Macro Blocks To be overridden by subclasses in order to create the appropriate subclass of MacroBlock in the parallel hierarchy. i.e. XBlocks are composed of XMacroBlocks

Specified by:

newMacroBlock in class TopLevelBlock

Parameters:

block_position - Starting position for the new macro block

h - Number of non-zeros associated with the macro block

Throws:

InternalErrorException

InconsistentLinearSystemException
