Member Typedef Documentation

typedef std::list<Asn1Buffer*> OSB_LIB::Asn1BufferCache::Buffers [private]

STL container for the buffers.

A std::set<Asn1Buffer*> would allow better control over the buffers in use.
However performance tests have shown that rebalancing of the set's tree after insert/erase is too expensive. (Old logic should be available in older versions of the file.)

Member Function Documentation

Asn1Buffer* OSB_LIB::Asn1BufferCache::get

(

)

[private]

Get a buffer from the cache.

Returns:

An Asn1Buffer, it has no content.
The buffer should be returned to the cache with put() if it is no more used.

Takes a buffer from pool_ (or creates a new buffer if the pool is empty) and returns it to the called.

Asn1BufferCache& OSB_LIB::Asn1BufferCache::operator=

(

const Asn1BufferCache &

)

[private]

Prevent assignment until needed: not implemented.

void OSB_LIB::Asn1BufferCache::put

(

Asn1Buffer *

buf

)

[private]

Put a buffer to the cache.

Parameters:

buf

Asn1Buffer to add, its data is cleared.
