Detailed Description

An output stream that writes data to a memory buffer If the buffer is to small, it will be enlarged automatically.

Constructor & Destructor Documentation

PdfMemoryOutputStream() [1/2]

PdfMemoryOutputStream::PdfMemoryOutputStream

(

size_t

initialSize = INITIAL_SIZE

)

Construct a new PdfMemoryOutputStream

Parameters

lInitial

initial size of the buffer

PdfMemoryOutputStream() [2/2]

PdfMemoryOutputStream::PdfMemoryOutputStream	(	char *	buffer,
		size_t	len
	)

Construct a new PdfMemoryOutputStream that writes to an existing buffer

Parameters

buffer	handle to the buffer
len	length of the buffer

Member Function Documentation

Close()

void PdfMemoryOutputStream::Close ( )

overridevirtual

Close the PdfOutputStream. This method may throw exceptions and has to be called before the destructor to end writing.

No more data may be written to the output device after calling close.

Implements mm::PdfOutputStream.

GetLength()

size_t mm::PdfMemoryOutputStream::GetLength ( ) const

inline

Returns

the length of the written data

TakeBuffer()

unique_ptr< char[]> PdfMemoryOutputStream::TakeBuffer

(

size_t &

length

)

Returns

a handle to the internal buffer.

The internal buffer is now owned by the caller and will not be deleted by PdfMemoryOutputStream. Further calls to Write() are not allowed.

The caller has to free() the returned malloc()'ed buffer!
