Constructor Detail

PartialDependency

public PartialDependency()

Default Constructor for a PartialDependency. Dependency and Successors are both set to 0.

PartialDependency

public PartialDependency(int successors,
                 double dependency)

Constructor that accepts successors and dependency for initialization.

Parameters:

successors - The number of successors that still have yet to be processed.

dependency - The dependency of a single node and a single source.

Method Detail

getDependency

public double getDependency()

Gets the dependency.

Returns:

The dependency value.

setDependency

public void setDependency(double dependency)

Sets the dependency value.

Parameters:

dependency - The value to set dependency to.

getSuccessors

public int getSuccessors()

Gets the number of successors that need to be processed.

Returns:

The successors value.

setSuccessors

public void setSuccessors(int successors)

Sets the number of successors.

Parameters:

successors - The value to set successors to.

addSuccessors

public void addSuccessors(int diff)

Update the successor count by a delta

Parameters:

diff - Value to increase the successors by.

addDependency

public void addDependency(double diff)

Add to the accumulated dependency value by a delta

Parameters:

diff - Value to accumulate by.
