示例1: Serialize
// Serializes to the given vector.
void TessdataManager::Serialize(GenericVector<char> *data) const {
ASSERT_HOST(is_loaded_);
// Compute the offset_table and total size.
int64_t offset_table[TESSDATA_NUM_ENTRIES];
int64_t offset = sizeof(int32_t) + sizeof(offset_table);
for (int i = 0; i < TESSDATA_NUM_ENTRIES; ++i) {
if (entries_[i].empty()) {
offset_table[i] = -1;
} else {
offset_table[i] = offset;
offset += entries_[i].size();
}
}
data->init_to_size(offset, 0);
int32_t num_entries = TESSDATA_NUM_ENTRIES;
TFile fp;
fp.OpenWrite(data);
fp.Serialize(&num_entries);
fp.Serialize(&offset_table[0], countof(offset_table));
for (int i = 0; i < TESSDATA_NUM_ENTRIES; ++i) {
if (!entries_[i].empty()) {
fp.Serialize(&entries_[i][0], entries_[i].size());
}
}
}示例2: SaveDocument
// Writes all the pages to the given filename. Returns false on error.
bool DocumentData::SaveDocument(const char* filename, FileWriter writer) {
TFile fp;
fp.OpenWrite(NULL);
if (!pages_.Serialize(&fp) || !fp.CloseWrite(filename, writer)) {
tprintf("Serialize failed: %s\n", filename);
return false;
}
return true;
}示例3: SaveToBuffer
bool DocumentData::SaveToBuffer(GenericVector<char>* buffer) {
TFile fp;
fp.OpenWrite(buffer);
return pages_.Serialize(&fp);
}
