Detailed Description

Buffer to store encoded data of one ASN.1 type.

Definition at line 121 of file asn1writer.h.

Public Member Functions

• Asn1Buffer (Asn1BufferCache &cache)

  Constructor with cache that owns the buffer.
  

• void destroy ()

  Destroy the buffer.
  

• void add (const Asn1Encoder &encoder, bool force=false)

  Add a constructed ASN.1 type.
  

• void add (const Asn1DataEncoder &encoder, bool force=false)

  Add a primitive ASN.1 type.
  

• bool write (FILE *out) const

  Write binary ASN.1 data to an output file.

  Clear the data of the buffer.
  

Private Types

• typedef std::list< Asn1Buffer * > Members

  STL container to store subtypes.
  

Private Member Functions

• ~Asn1Buffer ()

  Destructor: force creation on the heap.
  

• Asn1Buffer (const Asn1Buffer &)

  Prevent copying until needed: not implemented.
  

• Asn1Buffer & operator= (const Asn1Buffer &)

  Prevent assignment until needed: not implemented.
  

• size_t memberSize () const

  Number of bytes of the members_.
  

• bool getData (const Asn1Encoder &encoder, bool force)

  Get the data of a constructed ASN.1 type.
  

• bool getData (const Asn1DataEncoder &encoder, bool force)

  Get the data of a primitive ASN.1 type.
  

Private Attributes

• size_t totSize_

  Size of binary data, incl. tag and data length.
  

• Asn1Data data_

  Binary ASN.1 data.
  

• Members members_

  Members of the ASN.1 constructed type.
  

• Asn1Tag tag_

  Tag of the encoded data.
  

• Asn1Len dataLen_

  Size of the encoded data.
  

• Asn1Data tagBuf_

  Buffer to encode the tag and data length.
  

• Asn1BufferCache & cache_

  Cache that owns the buffer.
  

Friends

• class Asn1Writer

  Allow the ASN.1 writer to:

  • own a buffer
  • call getData().

  
  

• class Asn1BufferCache

  Give access to totSize_.

Member Function Documentation

void OSB_LIB::Asn1Buffer::add	(	const Asn1DataEncoder &	encoder,
		bool	force = false
	)

Add a primitive ASN.1 type.

Parameters:

	encoder	Encode to use to get the data.
	force	Flag to add the ASN.1 type even if it has no data.

Calls operator() of encoder with data_.

void OSB_LIB::Asn1Buffer::add	(	const Asn1Encoder &	encoder,
		bool	force = false
	)

Add a constructed ASN.1 type.

Parameters:

	encoder	Encode to use to get the data.
	force	Flag to add the ASN.1 type even if it has no data.

Calls operator() of encoder with itself.

void OSB_LIB::Asn1Buffer::clearData

(

)

Clear the data of the buffer.

Returns the content of members_ to the cache_.

For performance reasons only data_ and members_ are cleared, but not the other data members.

void OSB_LIB::Asn1Buffer::destroy

(

)

Destroy the buffer.

bool OSB_LIB::Asn1Buffer::getData	(	const Asn1DataEncoder &	encoder,
		bool	force
	)			[private]

Get the data of a primitive ASN.1 type.

Parameters:

	encoder	Encode to use to get the data.
	force	Flag to add the ASN.1 type even if it has no data.

Returns:

true if ASN.1 data have been generated, else false.

Calls operator() of encoder with data_.

bool OSB_LIB::Asn1Buffer::getData	(	const Asn1Encoder &	encoder,
		bool	force
	)			[private]

Get the data of a constructed ASN.1 type.

Parameters:

	encoder	Encode to use to get the data.
	force	Flag to add the ASN.1 type even if it has no data.

Returns:

true if ASN.1 data have been generated, else false.

Calls operator() of encoder with itself.

size_t OSB_LIB::Asn1Buffer::memberSize

(

)

const [private]

Number of bytes of the members_.

Asn1Buffer& OSB_LIB::Asn1Buffer::operator=

(

const Asn1Buffer &

)

[private]

Prevent assignment until needed: not implemented.

bool OSB_LIB::Asn1Buffer::write

(

FILE *

out

)

const

Write binary ASN.1 data to an output file.

Returns:

true if successful, else false.
