protected void appendClauseChunk(StringBuffer sbuffer,
                     String[] clauseTokens)

    Handles a clause query chunk.
    The default implementation considers the first token as a clause function ID and delegates the call to the function.
    
    Extending query executers can override this to implement custom query clause handling.
    
    Parameters:
    sbuffer - the query text buffer
    clauseTokens - clause tokens
    
    Throws:
    
    JRRuntimeException - if there is no first token or no clause function is found for the ID
