## org.apache.commons.collections.collection
Class UnmodifiableBoundedCollection

    java.lang.Object
      org.apache.commons.collections.collection.AbstractCollectionDecorator
          org.apache.commons.collections.collection.AbstractSerializableCollectionDecorator
              org.apache.commons.collections.collection.UnmodifiableBoundedCollection

All Implemented Interfaces:
  java.io.Serializable, java.lang.Iterable, java.util.Collection, BoundedCollection

    public final class UnmodifiableBoundedCollection

extends AbstractSerializableCollectionDecorator
implements BoundedCollection

`UnmodifiableBoundedCollection` decorates another `BoundedCollection` to ensure it can't be altered.

If a BoundedCollection is first wrapped in some other collection decorator, such as synchronized or predicated, the BoundedCollection methods are no longer accessible. The factory on this class will attempt to retrieve the bounded nature by examining the package scope variables.

This class is Serializable from Commons Collections 3.1.

Since:
  Commons Collections 3.0

Method Detail

### decorate

    public static BoundedCollection decorate(BoundedCollection coll)

  Factory method to create an unmodifiable bounded collection.

  Parameters:
    `coll` - the `BoundedCollection` to decorate, must not be null
  Returns:
    a new unmodifiable bounded collection
  Throws:
    `java.lang.IllegalArgumentException` - if bag is null

### decorateUsing

  Factory method to create an unmodifiable bounded collection.

  This method is capable of drilling down through up to 1000 other decorators to find a suitable BoundedCollection.

  Parameters:
    `coll` - the `BoundedCollection` to decorate, must not be null
  Returns:
    a new unmodifiable bounded collection
