IntPool

class emlib.containers.IntPool(capacity, start=0, fixedsize=True)

Bases: object

A pool of intergers

A pool will contain the integers in the range [start, start + capacity)

Parameters:

• capacity (int) – the capacity (size) of the pool.

• start – first element

• fixedsize – if True, this pool cannot be extended. Otherwise, when a pop operation would result in an empty pool the pool is doubled in size, adding the new items. A pool cannot be extended by adding elements outside its range, so a push operation might still fail if the item is outside the range of the pool

Example

>>> from emlib.containers import IntPool
>>> pool = IntPool(10)
>>> token = pool.pop()
>>> len(pool)
9
>>> pool.push(token)
>>> len(pool)
10
>>> pool.push(4)
ValueError: token 4 already in pool

Methods Summary

pop()	Take an item from the pool
push(token)	Return an item to the pool
