Public Member Functions
	Eitem (Evector< T > &vec, const Einteger &idx)
	Constructs a proxy item using an encrypted index.

	Eitem (Evector< T > &vec, const size_t idx)
	Constructs a proxy item using a plaintext index.

	operator T () const
	Implicit conversion to the underlying encrypted type T.

template<typename V , typename = std::enable_if_t<std::is_constructible_v<V, T> && !std::is_same_v<V, T>>>
	operator V () const
	Implicit conversion to any type constructible from T (e.g., derived types like Euint64).

const T &	operator= (const T &value)

Detailed Description

template<typename T, typename U>
class computefhe::Eitem< T, U >

Proxy object for accessing and modifying elements in an Evector using encrypted indices.

Eitem acts as a bridge between the vector and encrypted logic. When an operation is performed on an Eitem initialized with an encrypted index, the library performs the operation across all elements of the underlying vector using multiplexers (MUX) to ensure the secret index is not leaked.

Template Parameters

T	The encrypted type stored in the vector (i.e., Einteger).
U	The corresponding plaintext type for constant operations.

The documentation for this class was generated from the following file:
