【源码】protobuf 中各个压缩（Serialize）、解压缩（Parse）函数辨析

PROTOBUF_ATTRIBUTE_REINITIALIZES bool ParseFromString(ConstStringParam data);

PROTOBUF_ATTRIBUTE_REINITIALIZES bool ParsePartialFromString(

ConstStringParam data);

// Parse a protocol buffer contained in an array of bytes.

PROTOBUF_ATTRIBUTE_REINITIALIZES bool ParseFromArray(const void* data,

int size);

PROTOBUF_ATTRIBUTE_REINITIALIZES bool ParsePartialFromArray(const void* data,

int size);

// Reads a protocol buffer from the stream and merges it into this

// Message. Singular fields read from the what is

// already in the Message and repeated fields are appended to those

// already present.

//

// It is the responsibility of the caller to call input->LastTagWas()

// (for groups) or input->ConsumedEntireMessage() (for non-groups) after

// this returns to verify that the message’s end was delimited correctly.

//

// ParseFromCodedStream() is implemented as Clear() followed by

// MergeFromCodedStream().

bool MergeFromCodedStream(io::CodedInputStream* input);

// Like MergeFromCodedStream(), but succeeds even if required fields are

// missing in the input.

//

// MergeFromCodedStream() is just implemented as MergePartialFromCodedStream()

// followed by IsInitialized().

bool MergePartialFromCodedStream(io::CodedInputStream* input);

// Merge a protocol buffer contained in a string.

bool MergeFromString(ConstStringParam data);
