FixedLengthFIFO
public FixedLengthFIFO(int size)
- Construct a FIFO of a fixed (maximum) length.
- Parameters:
size - The maximum number of items to hold in the FIFO
size
public int size()
- Specified by:
size in interface java.util.Collection<T>- Specified by:
size in interface java.util.List<T>
isEmpty
public boolean isEmpty()
- Specified by:
isEmpty in interface java.util.Collection<T>- Specified by:
isEmpty in interface java.util.List<T>
contains
public boolean contains(java.lang.Object o)
- Specified by:
contains in interface java.util.Collection<T>- Specified by:
contains in interface java.util.List<T>
iterator
public java.util.Iterator<T> iterator()

add
public boolean add(T o)
- Add an element to the FIFO. Unlike a normal List, this FIFO
will not grow indefinitely, but adding will not make the FIFO
exceed its fixed size.
- Specified by:
add in interface java.util.Collection<T>- Specified by:
add in interface java.util.List<T>
- Parameters:
o -
- Returns:
- True, since you can always add one more object.
remove
public boolean remove(java.lang.Object o)
- Remove the given element if it's still in the FIFO.
- Specified by:
remove in interface java.util.Collection<T>- Specified by:
remove in interface java.util.List<T>
- Parameters:
o - The element to be removed.
