Public Member Functions
	gzip_istreambuf (std::istream &src)
	Constructs a gzip-decompressing streambuf.

	gzip_istreambuf (std::istream &src, const detail::ResourceLimits &limits)
	Constructs a gzip-decompressing streambuf with resource limits.

	~gzip_istreambuf () override
	Destroys the streambuf and releases the zlib inflate context.

bool	BudgetExceeded () const
	Returns true if the decompressed size budget was exceeded while reading.

int	underflow () override
	Inflates compressed data into the output buffer when the get area is exhausted.

Detailed Description

Input streambuf that decompresses gzip-compressed data on the fly.

Reads compressed data from the underlying stream and inflates it into an internal output buffer. Uses zlib's inflate with gzip decoding.

Constructor & Destructor Documentation

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

inlineexplicit

Constructs a gzip-decompressing streambuf.

Parameters

src	The input stream containing gzip-compressed data.

Exceptions

InternalError If the zlib inflate context cannot be initialized.

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

inline

Constructs a gzip-decompressing streambuf with resource limits.

Parameters

src	The input stream containing gzip-compressed data.
limits	The resource budgets enforced while inflating.

Exceptions

InternalError If the zlib inflate context cannot be initialized.
