de::softpro::doc::OutputStream::OutputStream

(

SIGNDOC_OutputStream *

aImpl )

[inline]

Parameters:

[in]

aImpl

A pointer to the C structure.

virtual de::softpro::doc::OutputStream::~OutputStream

(

)

[inline, virtual]

Destructor.

Member Function Documentation

virtual void de::softpro::doc::OutputStream::close

(

)

[pure virtual]

Close the stream.

This function forces any buffered data to be written and closes the stream.

You should not write to the stream after calling this function.

Implementations of this class may define exceptions thrown by this function.

Implemented in de::softpro::doc::LibraryOutputStream.

virtual void de::softpro::doc::OutputStream::flush

(

)

[pure virtual]

Flush the stream.

This function forces any buffered data to be written.

Implementations of this class may define exceptions thrown by this function.

Implemented in de::softpro::doc::LibraryOutputStream.

SIGNDOC_OutputStream* de::softpro::doc::OutputStream::getImpl

(

)

[inline]

Internal.

virtual void de::softpro::doc::OutputStream::seek

(

int

aPos )

[pure virtual]

Seek to the specified position.

Throws an exception if the position is invalid or if seeking is not supported.

Parameters:

[in]

aPos

The position (the first octet is at position zero).

Implemented in de::softpro::doc::LibraryOutputStream.

virtual int de::softpro::doc::OutputStream::tell

(

)

const [pure virtual]

Retrieve the current position.

Throws an exception if the position cannot represented as non-negative int or if seeking is not supported.

Returns:

The current position (the first octet is at position zero)

Implemented in de::softpro::doc::LibraryOutputStream.

virtual void de::softpro::doc::OutputStream::write	(	const void *	aSrc,
		int	aLen
	)		[pure virtual]

Write octets to the stream.

Throws an exception on error.

Parameters:

[in]	aSrc	Pointer to buffer to be written.
[in]	aLen	Number of octets to write.

Implemented in de::softpro::doc::LibraryOutputStream.
