Method Detail

getDIFFERENTIABLES

public java.util.ArrayList<Differentiable> getDIFFERENTIABLES()

count

public int count()

Returns:

The number of Differentiable objects stored by an object of this class.

contains

public boolean contains(java.lang.String name)

Parameters:

name - The name of the Differentiable.

Returns:

true if a Differentiable exists by the name supplied.

indexOf

public int indexOf(java.lang.String name)

Parameters:

name - The name of the dependent variable of the Differentiable.

Returns:

the index of the Differentiable object that has the name supplied. If no such Differentiable object exists, then it returns -1.

getDifferentiable

public Differentiable getDifferentiable(java.lang.String name)
                                 throws java.lang.ClassNotFoundException

Parameters:

name - The name of the Differentiable.

Returns:

the Differentiable object that has the name supplied if it exists. If no such Differentiable object exists, then it returns null.

Throws:

java.lang.ClassNotFoundException - if no Differentiable object by that name exists.

getDifferentiable

public Differentiable getDifferentiable(int index)
                                 throws java.lang.ClassNotFoundException

Parameters:

index - The index of the Differentiable in this DifferentiableManager object. If no such index exists, then it returns null.

Throws:

java.lang.ClassNotFoundException - if no Differentiable object by that name exists.

lookUp

public Differentiable lookUp(java.lang.String name)

Attempts to retrieve a Differentiable object from a DifferentiableManager based on its name.

Parameters:

name - The name of the Differentiable object.

Returns:

the Differentiable object that has that name or null if the Differentiable is not found.

add

public void add(Differentiable diff)

Parameters:

diff - The Differentiable object to add to this object.

delete

public void delete(java.lang.String name)

Removes a Differentiable object from this DifferentiableManager.

firstDifferentiable

public Differentiable firstDifferentiable()

lastDifferentiable

public Differentiable lastDifferentiable()

update

public int update(java.lang.String name,
                  java.lang.String newName)

It updates the name of a Differentiable object in this DifferentiableManager with the parameter newName.

Parameters:

name - The name of the Differentiable in this DifferentiableManager that we wish to update.

newName - The new name to give the Differentiable.

Returns:

The index of the object, if a Differentiable by that name is already recorded in the DifferentiableManager and -1 the Differentiable is not found.

update

public int update(java.lang.String name,
                  java.util.ArrayList<java.lang.String> data)

Updates a Differentiable object in this DifferentiableManager.

Parameters:

name - The name of the Differentiable object to be updated.

data - The data to be used to update the object if found.

Returns:

The index of the object, if a Differentiable by that name is already recorded in the DifferentiableManager and -1 the Differentiable is not found.

clearAll

public void clearAll()
