const BuilderPtr real(double x) override
Adds a real value x to the accumulated data.
const BuilderPtr endlist() override
Ends a nested list.
static const BuilderPtr fromempty(const BuilderOptions &options)
Create an empty Float64Builder.
const BuilderPtr timedelta(int64_t x, const std::string &unit) override
Adds a timedelta value x to the accumulated data.
void field(const char *key, bool check) override
Sets the pointer to a given record field key; the next command will fill that slot.
GrowableBuffer< double > buffer()
Contains the accumulated real numbers (double).
const BuilderPtr complex(std::complex< double > x) override
Adds a complex value x to the accumulated data.
const BuilderPtr index(int64_t index) override
Sets the pointer to a given tuple field index; the next command will fill that slot.
int64_t length() const override
Current length of the accumulated array.
const BuilderPtr endrecord() override
Ends a record.
Float64Builder(const BuilderOptions &options, GrowableBuffer< double > buffer)
Create a Float64Builder from a full set of parameters.
static const BuilderPtr fromint64(const BuilderOptions &options, const GrowableBuffer< int64_t > &old)
Create a Float64Builder from an existing Int64Builder.

Adds an integer value x to the accumulated data.
const BuilderPtr datetime(int64_t x, const std::string &unit) override
Adds a datetime value x to the accumulated data.
const BuilderPtr beginrecord(const char *name, bool check) override
Begins building a record with an optional name.
const BuilderPtr null() override
Adds a null value to the accumulated data.
const std::string to_buffers(BuffersContainer &container, int64_t &form_key_id) const override
Copy the current snapshot into the BuffersContainer and return a Form as a std::string (JSON).

Begins building a nested list.
const BuilderPtr boolean(bool x) override
Adds a boolean value x to the accumulated data.
const BuilderPtr begintuple(int64_t numfields) override
Begins building a tuple with a fixed number of fields.
const BuilderPtr endtuple() override
Ends a tuple.
const std::string classname() const override
User-friendly name of this class: "Float64Builder".
void clear() override
Removes all accumulated data without resetting the type knowledge.
