public Page(String url,
            int urlID)

Construct a new page object.

Parameters:

url - URL of the Page

urlID - assigned ID for this page

Method Detail

public int getURLID()

Get the urlID of this URL

Returns:

int of url

getURL

public String getURL()

Get the url String for this URL object

Returns:

String of url

equals

public boolean equals(Object obj)

Override for the equals() method so that contains() will do proper comparison for ArrayList

Overrides:

equals in class Object

Parameters:

obj - Page object to be compared

Returns:

True, if the two URLs are equal or the two URLIDs are the same; false, otherwise.

compareTo

public int compareTo(Page candidate)

Since we implement the Comparable interface, we must provide a method that describes how two Page objects should be compared. We will be sorting our Page ArrayList by URLID, so we need to sort our List in ascending order (lowest ID's first).

Specified by:

compareTo in interface Comparable<Page>

Parameters:

candidate - Page that 'this' Page is being compared to

Returns:

-1 if this page has a lower ID, 0 if the same, 1 if this ID is higher.
