public EntityResolverWrapper() 
{

}

Default constructor.

 public EntityResolverWrapper(EntityResolver entityResolver) 
{

}

Wraps the specified SAX entity resolver.

 public EntityResolver getEntityResolver() 
{
        return fEntityResolver;
}

Returns the SAX entity resolver.

}

Resolves an external parsed entity. If the entity cannot be resolved, this method should return null.

 public  void setEntityResolver(EntityResolver entityResolver) 
{
        fEntityResolver = entityResolver;
}

Sets the SAX entity resolver.
