Inheritance diagram for keepass::hashed_istreambuf:

Public Member Functions
	hashed_istreambuf (std::istream &src)
	Constructs an input streambuf that reads from the given stream.
bool	BudgetExceeded () const
	Returns true if a resource budget was exceeded while reading.
	hashed_istreambuf (std::istream &src, const detail::ResourceLimits &limits)
	Constructs an input streambuf with explicit resource limits.
int	underflow () override
	Reads and verifies the next block when the get area is exhausted.

Detailed Description

Input streambuf that reads SHA-256-hashed, block-structured data.

Each block consists of a BlockHeader followed by the raw data. The hash in the header is verified against the data on read. An empty block with a zero hash signals end-of-stream.

Constructor & Destructor Documentation

hashed_istreambuf() [1/2]

keepass::hashed_istreambuf::hashed_istreambuf ( std::istream &  src )

inlineexplicit

Constructs an input streambuf that reads from the given stream.

Parameters

src	The input stream to read hashed blocks from.

hashed_istreambuf() [2/2]

keepass::hashed_istreambuf::hashed_istreambuf ( std::istream &  src, const detail::ResourceLimits &  limits  )

inline

Constructs an input streambuf with explicit resource limits.

Parameters

src	The input stream to read hashed blocks from.
limits	The resource budgets enforced while reading.
