示例1: unserialize
void String::unserialize(VariableUnserializer *uns,
char delimiter0 /* = '"' */,
char delimiter1 /* = '"' */) {
int64_t size = uns->readInt();
if (size >= RuntimeOption::MaxSerializedStringSize) {
throw Exception("Size of serialized string (%d) exceeds max", int(size));
}
if (size < 0) {
throw Exception("Size of serialized string (%d) must not be negative",
int(size));
}
uns->expectChar(':');
uns->expectChar(delimiter0);
StringData *px = StringData::Make(int(size));
auto const buf = px->bufferSlice();
assert(size <= buf.len);
uns->read(buf.ptr, size);
px->setSize(size);
if (m_px) decRefStr(m_px);
m_px = px;
px->setRefCount(1);
uns->expectChar(delimiter1);
}
示例2: concat3
String concat3(const String& s1, const String& s2, const String& s3) {
StringSlice r1 = s1.slice();
StringSlice r2 = s2.slice();
StringSlice r3 = s3.slice();
int len = r1.len + r2.len + r3.len;
StringData* str = StringData::Make(len);
auto const r = str->bufferSlice();
memcpy(r.ptr, r1.ptr, r1.len);
memcpy(r.ptr + r1.len, r2.ptr, r2.len);
memcpy(r.ptr + r1.len + r2.len, r3.ptr, r3.len);
str->setSize(len);
return str;
