java.lang.Objectcern.colt.PersistentObject
cern.colt.map.AbstractMap
Abstract base class for hash maps holding objects or primitive data types such as int, float, etc. as keys and/or values.
First see the package summary and javadoc tree view to get the broad picture.
Note that implementations are not synchronized.

| abstract  void | clear()Removes all (key,value) associations from the receiver. | 
|  void | ensureCapacity(int minCapacity)Ensures that the receiver can hold at least the specified number of elements without needing to allocate new internal memory. | 
|  boolean | isEmpty()Returns true if the receiver contains no (key,value) associations. | 
|  int | size()Returns the number of (key,value) associations currently contained. | 
|  void | trimToSize()Trims the capacity of the receiver to be the receiver's current size. |

public abstract void clear()
public void ensureCapacity(int minCapacity)
This method never need be called; it is for performance tuning only. Calling this method before put()ing a large number of associations boosts performance, because the receiver will grow only once instead of potentially many times.
This default implementation does nothing. Override this method if necessary.
minCapacity - the desired minimum capacity.public boolean isEmpty()
public int size()
public void trimToSize()
This default implementation does nothing. Override this method if necessary.
