◆ ParamCheck1

#define ParamCheck1 (   exp)
Value:
std::cout << exp << " in " << __func__ << "() in " << __LINE__ << " in " \
<< __FILE__;

◆ DealData()

template<typename T >
void DealData ( const vector< string > &  vbuf,
vector< OCP_USI > &  obj,
vector< T > &  region 
)

DealData change a series of product of integers into two arrays. For example, 8*1 16*2 8*3 16*4 -> obj <8, 16, 8, 16> & val <1, 2, 3, 4>.

Definition at line 59 of file UtilInput.hpp.

60 {
61  obj.resize(0);
62  region.resize(0);
63  for (auto& str : vbuf) {
64  auto pos = str.find('*');
65  if (pos != string::npos) {
66  USI len = str.size();
67  OCP_USI num = stoi(str.substr(0, pos));
68  USI val = stoi(str.substr(pos + 1, len - (pos + 1)));
69  obj.push_back(num);
70  region.push_back(val);
71  }
72  }
73 }
unsigned int USI
Generic unsigned integer.
Definition: OCPConst.hpp:23
unsigned int OCP_USI
Long unsigned integer.
Definition: OCPConst.hpp:25

◆ DealDefault()

void DealDefault ( vector< string > &  result)

DealDefault is used to deal with the expression with asterisk, for example m*n -> <n,...,n> size m , m* -> <DEFAULT,..., DEFAULT> size m.

Definition at line 50 of file UtilInput.cpp.

51 {
52  vector<string> tmp;
53  for (auto& str : result) {
54  auto pos = str.find('*');
55  if (pos == string::npos) {
56  tmp.push_back(str);
57  } else {
58  USI num = atoi(str.substr(0, pos).c_str()); // non number -> 0
59  USI len = str.size();
60  string val = "DEFAULT";
61  if (num == 0) {
62  tmp.push_back(str);
63  } else {
64  if (pos != len - 1) {
65  val = str.substr(pos + 1, len - (pos + 1));
66  }
67  for (USI i = 0; i < num; i++) tmp.push_back(val);
68  }
69  }
70  }
71  swap(result, tmp);
72 }

◆ Map_Str2Int()

constexpr long long Map_Str2Int ( const char *  mystr,
const USI len 
)
inlineconstexpr

Map_str2int is used to map string to integer, which used to match the keyword efficiently in input file in the switch structure.

Definition at line 34 of file UtilInput.hpp.

35 {
36  long long res = 0;
37  long long t = 100;
38  for (USI i = 0; i < len; i++) {
39  res += (int)mystr[len - 1 - i] * t;
40  t *= 100;
41  }
42  return res;
43 }

◆ ReadLine()

OCP_BOOL ReadLine ( ifstream &  ifs,
vector< string > &  result 
)

ReadLine is the core function while inputting the file. It will capture the next line which is meanningful, for example, not blank line or comments, and then gets rid of some useless characters such as space, commas. Finally, the segments of rest string will be stored in result. And if return OCP_FALSE, it indicates we have reach the end of file.
