public BooleanClause(Query query,
    BooleanClause.Occur occur) 
{

}

Constructs a BooleanClause.

 public boolean equals(Object o) 
{
    if (!(o instanceof BooleanClause))
      return false;
    BooleanClause other = (BooleanClause)o;
    return this.query.equals(other.query)

}

Returns true iff o is equal to this.

{
    return occur;
}

 public Query getQuery() 
{
    return query;
}

 public int hashCode() 
{
    return query.hashCode() ^ (Occur.MUST.equals(occur)?1:0) ^ (Occur.MUST_NOT.equals(occur)?2:0);
}

Returns a hash code value for this object.

{
    return Occur.MUST_NOT.equals(occur);
}

{
    return Occur.MUST.equals(occur);
}

{
    this.occur = occur;
}

 public  void setQuery(Query query) 
{
    this.query = query;
}

 public String toString() 
{
    return occur.toString() + query.toString();
