Class XMacroBlock

java.lang.Object

solvers.linearSystem.btf.ComponentBlock

solvers.linearSystem.btf.macroBlocks.XMacroBlock

public class XMacroBlock
extends MacroBlock

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

XMacroBlock

public XMacroBlock(MacroBlock full_block,
 int current_class)

Method Details

subBlockCopy

protected MacroBlock subBlockCopy(int current_class)

Description copied from class: MacroBlock

Factory Method for sub-block creation This method is to be overridden by subclasses to instantiate a copy of the current block (of the correct type) For instance, a copy of an XMacroBlocks needs to be a XMacroBlock

Specified by:

subBlockCopy in class MacroBlock

Parameters:

current_class - The class for which the copy is created

Returns:

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

LUPDecompose

public void LUPDecompose(boolean in_place)
                  throws InconsistentLinearSystemException

Throws:

InconsistentLinearSystemException

newMicroBlock

protected MicroBlock newMicroBlock(Position block_position,
 int h)
                            throws InconsistentLinearSystemException,
InternalErrorException

Description copied from class: MacroBlock

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

Specified by:

newMicroBlock in class MacroBlock

Parameters:

block_position - Starting position for the new macro block

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

Throws:

InconsistentLinearSystemException

InternalErrorException
