public BooleanClause(Query query,
    Occur occur) 
{
    this.query = query;

}

Constructs a BooleanClause.

{
    if (o == null || !(o instanceof BooleanClause))
      return false;
    BooleanClause other = (BooleanClause)o;
    return this.query.equals(other.query)

}

Returns true if o is equal to this.

 public Occur getOccur() 
{
    return occur;
}

 public Query getQuery() 
{
    return query;
}

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

Returns a hash code value for this object.

{
    return Occur.MUST_NOT == occur;
}

 public boolean isRequired() 
{
    return Occur.MUST == occur;
}

}

 public  void setQuery(Query query) 
{

}

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