Member Function Documentation

calculate_encode_length()

unsigned long long Gcs_empty_stage_metadata::calculate_encode_length ( ) const

finalvirtual

Calculate the length required to encode this object.

Implements Gcs_stage_metadata.

clone()

std::unique_ptr< Gcs_stage_metadata > Gcs_empty_stage_metadata::clone ( )

finalvirtual

Creates a deep copy of this object.

Returns

a deep copy of this object.

Implements Gcs_stage_metadata.

decode()

unsigned long long Gcs_empty_stage_metadata::decode ( unsigned char const *  buffer )

finalvirtual

Decode the contents of the buffer and sets the field values according to the values decoded.

The buffer MUST be encoded in little endian format.

Parameters

buffer

The buffer to decode from.

Returns

Encoded size.

Implements Gcs_stage_metadata.

dump()

void Gcs_empty_stage_metadata::dump ( std::ostringstream &  output ) const

finalvirtual

Create a string representation of the header to be logged.

Parameters

output

Reference to the output stream where the string will be created

Implements Gcs_stage_metadata.

encode()

unsigned long long Gcs_empty_stage_metadata::encode ( unsigned char *  buffer ) const

finalvirtual

Encode the contents of this instance into the buffer.

The encoding SHALL be done in little endian format.

Parameters

buffer

The buffer to encode to.

Returns

Length of the encoded information.

Implements Gcs_stage_metadata.
