關於從映射中檢索數據的問題

這是智能合約。

pragma solidity ^0.4.8;

contract RecordCreation {

uint public count;
mapping (address => string) public usertype;
struct Patientdetails{

}
Patientdetails[] public patientdetails;

mapping (address => uint[]) public PatientDocuments;
function RecordCreation(){

}
//Function user type definition
function userDefinition(string utype1) payable returns(bool result) {

}
//Data Submission Function
function patientDataSubmission() payable returns (bool result){

}
//Documents Count Retrieval Function for  a Patient
function countOfDataSubmission(address patientaddress) payable returns (uint result){

}
function getPatientsCount(address patientaddress)
   constant returns (uint count) {

}

}
