Detailed Description

Represents the content of a file (Binary Large Object).

This is the lowest-level object in the VCS, storing only raw file bytes. The Blob object is immutable; its hash is solely dependent on its content.

Constructor & Destructor Documentation

Blob()

svcs::core::Blob::Blob

(

std::string

raw_data

)

Constructor for the Blob object.

Initializes the object and immediately computes its hash ID based on the raw_data.

Parameters

raw_data

The raw file content to be stored and hashed.

Member Function Documentation

getData()

const std::string & svcs::core::Blob::getData ( ) const

nodiscard

Returns the raw data content stored in the Blob.

Returns

const std::string& A constant reference to the file content.

getType()

std::string svcs::core::Blob::getType ( ) const

nodiscardoverridevirtual

Returns the type of the VCS object.

Returns

std::string Always returns "blob". Pure virtual method to get the type of the VCS object.

This is crucial for object storage and reconstruction (e.g., "commit", "blob", "tree").

Returns

std::string The type identifier of the object.

Implements svcs::core::VcsObject.

serialize()

std::string svcs::core::Blob::serialize ( ) const

nodiscardoverridevirtual

Serializes the object's core data for hashing and storage.

Returns

std::string Returns the raw file content (data) itself. Pure virtual method to serialize the object's core data.

The returned string content is what will be hashed and stored in the database.

Returns

std::string The standardized, serialized data of the object.

Implements svcs::core::VcsObject.
