方法详细资料

encode

byte[] encode(T t)
       throws IOException

Do byte encode action

参数:

t - generic target object

返回:

encoded byte array

抛出:

IOException - if target object is invalid

decode

T decode(byte[] bytes)
  throws IOException

Do decode action from byte array

参数:

bytes - encoded byte array

返回:

parse byte array to target object

抛出:

IOException - if byte array is invalid

size

int size(T t)
  throws IOException

Calculate size of target object

参数:

t - target object

返回:

size of

抛出:

IOException - if target object is invalid

writeTo

void writeTo(T t,
             com.google.protobuf.CodedOutputStream out)
      throws IOException

Write target object to byte array

参数:

t - target object

out - target CodedOutputStream

抛出:

IOException - if target object is invalid

readFrom

T readFrom(com.google.protobuf.CodedInputStream intput)
    throws IOException

Read object from target byte array input stream

参数:

intput - target input stream object

返回:

unserialize object

抛出:

IOException - if byte array is invalid

getDescriptor

com.google.protobuf.Descriptors.Descriptor getDescriptor()
                                                  throws IOException

Get Descriptor to support dynamic mesage call for protocol buffer

返回:

Descriptors.Descriptor instance

抛出:

IOException - in case of create Descriptors.Descriptor failed
