Member Function Documentation

deserialize() [1/2]

virtual Reader& eip::EncapHeader::deserialize ( Reader &  reader, size_t  length  )

inlinevirtual

Deserialize data from the given reader with the length given. Length must be 24 or a length_error is thrown

Parameters

reader	Reader to use for deserialization
length	Length expected for data, must be 24

Returns

the reader again

Exceptions

std::length_error

if the buffer is overrun while deserializing

Implements eip::serialization::Serializable.

Definition at line 89 of file encap_header.h.

deserialize() [2/2]

Reader & eip::EncapHeader::deserialize ( Reader &  reader )

virtual

Deserialize data from the given reader without length information

Parameters

reader

Reader to use for deserialization

Returns

the reader again

Exceptions

std::length_error

if the buffer is overrun while deserializing

Implements eip::serialization::Serializable.

Definition at line 46 of file encap_header.cpp.

getLength()

virtual size_t eip::EncapHeader::getLength ( ) const

inlinevirtual

Always returns 24, the size of the encapsulation packer header

Returns

Total length in bytes to be serialized, always 24 bytes

Implements eip::serialization::Serializable.

Definition at line 68 of file encap_header.h.

serialize()

Writer & eip::EncapHeader::serialize ( Writer &  writer ) const

virtual

Serialize data into the given buffer

Parameters

writer

Writer to use for serialization

Returns

the writer again

Exceptions

std::length_error

if the buffer is too small for the header data

Implements eip::serialization::Serializable.
