FundamentalDiagramImpl

public FundamentalDiagramImpl(FundamentalDiagramImpl fundamentalDiagramImpl)

Copy Constructor

Parameters:

fundamentalDiagramImpl - to copy

Method Detail

getFreeFlowBranch

public FundamentalDiagramBranch getFreeFlowBranch()

Free flow branch of the FD

Specified by:

getFreeFlowBranch in interface FundamentalDiagram

Returns:

free flow branch

getCongestedBranch

public FundamentalDiagramBranch getCongestedBranch()

Congested branch of the FD

Specified by:

getCongestedBranch in interface FundamentalDiagram

Returns:

congested branch

relaxedHashCode

public int relaxedHashCode(int scale)

A fundamental diagram is based on a limited number of double variables to define it. In case we want to use the same FD for extremely similar variables we can use this relaxed hash code that ensures that for the given precision level identical hashes are created even if the underlying floating point variables differ beyond this precision.

Specified by:

relaxedHashCode in interface FundamentalDiagram

Parameters:

scale - indicating how many decimals to consider, e.g., 2 considers 2 decimals for precision

Returns:

created relaxed hash code

clone

public abstract FundamentalDiagram clone()

Clone the fundamental diagram

Specified by:

clone in interface FundamentalDiagram

Overrides:

clone in class Object

Returns:

cloned instance
