Constructor Detail

ProductItemGroup

public ProductItemGroup()

Constructor

ProductItemGroup

public ProductItemGroup(java.lang.String isim)

Constructor

Parameters:

isim - sets the name

ProductItemGroup

public ProductItemGroup(java.util.Collection o)

Constructor

Parameters:

o - adds o to the product tree, where o is another product tree

Method Detail

addProduct

public void addProduct(ProductItem p)

Method

Parameters:

p - add this product

addProduct

public void addProduct(ProductItemGroup p)

Method

Parameters:

p - add this product tree

prepareForManufacture

public boolean prepareForManufacture(int amount)

Method

Parameters:

amount - prepare manufacture of this amount of product, using the product tree In the project documentation, we were asked to both return false and throw an exception. Although, I implemented both, since we can not realize both, I choose returning false. This method should check that for each type=4 product in the productgroup, there is enough in the stock to produce the given amount. If for any productItem, there is not enough stock, it should give an exception error and return false; otherwise it should return true;

manufactureProduct

public void manufactureProduct(int amount)

Method

Parameters:

amount - produce by the specified amount This method first checks if the associated machine is ready – if so manufactures the given productgroup by the given amount. In doing so, it decreases the stock amounts of all the used components by the given amount and increases the stock amount of the produced product by the given given amount.

removeProduct

public void removeProduct(ProductItem p)

Method

Parameters:

p - remove product p from the product tree

removeProduct

public void removeProduct(ProductItemGroup pp)

Method

printGroup

public void printGroup()

Method prints the whole product tree

printGroup

public void printGroup(ProductItemGroup pp)

Method

Parameters:

pp - print the sub-product tree pp
