Method Detail
-
add
public int add(int listID)
Allocates a new index resource and adds it to the front of the linked list indexed by listID.- Parameters:
listID
- the id of the list to add to.- Throws:
java.lang.IndexOutOfBoundsException
- thrown if the listID is not in the the range [0, numLists).
-
append
public int append(int listID)
Allocates a new index resource and adds it to the end of the linked list indexed by listID.- Parameters:
listID
- the id of the list to add to.- Throws:
java.lang.IndexOutOfBoundsException
- thrown if the listID is not in the the range [0, numLists).
-
remove
public void remove(int listID, int index)
Remove the index resource from the linked list indexed by listID.- Parameters:
listID
- the id of the list from which to removed the value at index.index
- the index of the value to be removed from the specified list.- Throws:
java.lang.IndexOutOfBoundsException
- thrown if the listID is not in the the range [0, numLists).
-
removeAll
public void removeAll(int listID)
Removes all indexes from the specified list.- Parameters:
listID
- the list to be emptied.
-
getNewCapacity
public int getNewCapacity()
Computes the next size that should be used to grow the index capacity.
-
getSize
public int getSize()
Returns the current number of used index resources.
-
getCapacity
public int getCapacity()
Returns the current index capacity.
-
getNumLists
public int getNumLists()
Returns the number of linked list being managed.
-
next
public final int next(int index)
Returns the next index resource that follows the given index in a linked list. The index should be an index that is in some linked list. Otherwise, the results are undefined( probably give you the next index on the free list )- Parameters:
index
- the index to search after for the next index.- Throws:
java.lang.IndexOutOfBoundsException
- thrown if the index is not in the the range [0, capacity].
-
first
public final int first(int listID)
Returns the first index resource on the linked list indexed by listID.- Throws:
java.lang.IndexOutOfBoundsException
- thrown if the listID is not in the the range [0, numLists].
-
growCapacity
public void growCapacity(int newCapacity)
Increases the index resource pool.- Parameters:
newCapacity
- the new number of resource indexes to manage. if this number is smaller than the current number of resource indexes, then nothing changes.
-
growNumLists
public void growNumLists(int newListSize)
Increases the number of managed linked lists.- Parameters:
newListSize
- the new number of linked lists. If this number is smaller than the current number of linked lists, then nothing changes.
-
clear
public void clear()
Removes all indexes from all lists.
-
getListSize
public int getListSize(int listID)
Returns the number of indexes in the specified list.- Parameters:
listID
- the id of the list from which to get the number of indexes.- Throws:
java.lang.IndexOutOfBoundsException
- thrown if the listID is not in the the range [0, numLists).
