Constructor & Destructor Documentation

util::stream::Link::Link

(

const ChainPosition &

position

)

[explicit]

Constructs an initialized link.

util::stream::Link::Link

(

)

Constructs a link that must subsequently be initialized.

Init

Definition at line 110 of file chain.cc.

util::stream::Link::~Link

(

)

Destructs the link object.

If necessary, this method will pass a poison block to this link's output producer queue.

Member Function Documentation

void util::stream::Link::Init

(

const ChainPosition &

position

)

Initializes the link with the input consumer queue and output producer queue at a given position in the chain.

Here is the caller graph for this function:

util::stream::Link::operator bool

(

)

const [inline]

Returns true if the block at this link encapsulates a valid (non-NULL) block of memory.

This method is a user-defined implicit conversion function to boolean; among other things, this method enables bare instances of this class to be used as the condition of an if statement.

Definition at line 320 of file chain.hh.

const Block& util::stream::Link::operator*

(

)

const [inline]

Gets a const reference to the block at this link.

Definition at line 296 of file chain.hh.

Block& util::stream::Link::operator*

(

)

[inline]

Gets a reference to the block at this link.

Definition at line 291 of file chain.hh.

Link & util::stream::Link::operator++

(

)

Gets the link at the next position in the chain.

Definition at line 143 of file chain.cc.

References util::PCQueue< T >::Consume(), util::PCQueue< T >::Produce(), and util::stream::Block::ValidSize().

Here is the call graph for this function:

const Block* util::stream::Link::operator->

(

)

const [inline]

Gets a const pointer to the block at this link.

Definition at line 306 of file chain.hh.

Block* util::stream::Link::operator->

(

)

[inline]

Gets a pointer to the block at this link.

Definition at line 301 of file chain.hh.

void util::stream::Link::Poison

(

)

Poisons the block at this link, and passes this now-poisoned block to this link's output producer queue.
