Public Member Methods
DLLLOCAL const char *	getName () override
	Returns the name of the class.
DLLLOCAL int64	peek (ExceptionSink *xsink) override
	Peeks the next byte from the input stream.
DLLLOCAL int64	read (void *ptr, int64 limit, ExceptionSink *xsink) override
	Reads up to `limit` bytes from the input stream.
Public Member Methods inherited from InputStream
DLLLOCAL QoreValue	peekHelper (ExceptionSink *xsink)
	Helper method that checks that the current thread is the same as when the instance was created, calls peek() and wraps the result to Qore's `int` value.
DLLLOCAL BinaryNode *	readHelper (int64 limit, ExceptionSink *xsink)
	Helper method that checks that the current thread is the same as when the instance was created, calls read() and wraps the read data to Qore's `binary` value.
Public Member Methods inherited from StreamBase
DLLLOCAL bool	check (ExceptionSink *xsink)
	Checks that the current thread is the same as when the instance was created or assigned via unassignThread() and reassignThread() and that the stream has not yet been closed.
DLLLOCAL int	getThreadId ()
	Get currently assigned thread id.
DLLLOCAL void	reassignThread (ExceptionSink *xsink)
	Reassigns current thread as thread used for stream manipulation, see check()
DLLLOCAL void	unassignThread (ExceptionSink *xsink)
	Unassigns current thread as thread used for stream manipulation, see check()
Public Member Methods inherited from AbstractPrivateData
virtual DLLLOCAL void	deref ()
	decrements the reference count of the object without the possibility of throwing a Qore-language exception
virtual DLLLOCAL void	deref (ExceptionSink *xsink)
	decrements the reference count of the object
DLLLOCAL void	ref () const
	increments the reference count of the object
Public Member Methods inherited from QoreReferenceCounter
DLLEXPORT	QoreReferenceCounter ()
	Creates the reference counter object.
DLLEXPORT	QoreReferenceCounter (const QoreReferenceCounter &old)
	Creates a new object with a reference count of 1.
DLLEXPORT	~QoreReferenceCounter ()
	destroys the reference counter object
DLLEXPORT bool	is_unique () const
	Returns true if the reference count is 1.
DLLEXPORT bool	optRef ()
	Make a strong reference only if the object is valid.
DLLEXPORT int	reference_count () const
	Gets the reference count.
DLLEXPORT bool	ROdereference () const
	Atomically decrements the reference count.
DLLEXPORT void	ROreference () const
	Atomically increments the reference count.

Additional Inherited Members
Private Member Methods inherited from InputStream
	InputStream ()=default
	Constructor.
Private Member Methods inherited from StreamBase
	StreamBase ()
	Constructor.
Private Member Methods inherited from AbstractPrivateData
virtual DLLLOCAL	~AbstractPrivateData ()
	as these objects are reference counted, the destructor should be called only when the reference count = 0 and not manually

Detailed Description

Private data for the Qore::BinaryInputStream class.

Member Function Documentation

getName()

DLLLOCAL const char * BinaryInputStream::getName ( )

inlineoverridevirtual

Returns the name of the class.

Returns

the name of the class

Implements StreamBase.

peek()

DLLLOCAL int64 BinaryInputStream::peek ( ExceptionSink *  xsink )

inlineoverridevirtual

Peeks the next byte from the input stream.

Parameters

xsink

the exception sink

Returns

the next byte available to be read, -1 indicates end of the stream, -2 indicates an error

Implements InputStream.

read()

DLLLOCAL int64 BinaryInputStream::read ( void *  ptr, int64  limit, ExceptionSink *  xsink  )

inlineoverridevirtual

Reads up to `limit` bytes from the input stream.

Parameters

ptr	the destination buffer to read data into
limit	the maximum number of bytes to read, must be > 0
xsink	the exception sink

Returns

the number of bytes read, 0 indicates the end of the stream

Implements InputStream.
