示例1: ExtractStringToken
static vsString ExtractStringToken( vsString &string )
{
vsString token;
size_t index = string.find(' ');
if ( index == vsString::npos )
{
token = string;
string = "";
}
else
{
token = string.substr(0, index);
string.erase(0,index+1);
// string = string.substr(index, vsString::npos);
}
return token;
}示例2: ExtractWhitespaceStringToken
static vsString ExtractWhitespaceStringToken( vsString &string ) // pull out a string defined by whitespace
{
vsString label;
size_t len = string.length();
size_t index = 0;
for ( index = 0; index < len; index++ )
{
if ( IsWhitespace(string[index]) ) // this character isn't alphabetic, so isn't part of the label
{
index--; // back up one character
break; // exit the loop
}
}
label = string.substr(0, index+1);
string.erase(0,index+1);
return label;
}示例3: ExtractNumberToken
static vsString ExtractNumberToken( vsString &string )
{
vsAssert(IsNumeric(string[0]), "Tried to extract a number from something that isn't a number!");
// okay. We need to find
vsString numberString;
size_t len = string.length();
size_t index = 0;
for ( index = 0; index < len; index++ )
{
if ( !IsNumeric(string[index]) ) // this character isn't alphabetic, so isn't part of the label
{
index--; // back up one character
break; // exit the loop
}
}
numberString = string.substr(0, index+1);
string.erase(0,index+1);
return numberString;
