Detailed Description

Utility class to serialize thrift objects to a binary format. This object should be reused if possible to reuse the underlying memory. Note: thrift will encode NULLs into the serialized buffer so it is not valid to treat it as a string.

Constructor & Destructor Documentation

impala::ThriftSerializer::ThriftSerializer	(	bool	compact,
		int	initial_buffer_size = `1024`
	)

If compact, the objects will be serialized using the Compact Protocol. Otherwise, we'll use the binary protocol. Note: the deserializer must be matching.

template<class T >

Status impala::ThriftSerializer::Serialize	(	T *	obj,
		std::vector< uint8_t > *	result
	)

inline

Serializes obj into result. Result will contain a copy of the memory.

template<class T >

Status impala::ThriftSerializer::Serialize	(	T *	obj,
		uint32_t *	len,
		uint8_t **	buffer
	)

inline

Serialize obj into a memory buffer. The result is returned in buffer/len. The memory returned is owned by this object and will be invalid when another object is serialized.
