| class | ACE_Stream_Iterator< ACE_SYNCH_USE > |
A Stream consists of a stack of <ACE_Modules>, each of which contains two <ACE_Tasks>. Even though the methods in this class are virtual, this class isn't really intended for subclassing unless you know what you are doing. In particular, the <ACE_Stream> destructor calls <close>, which won't be overridden properly unless you call it in a subclass destructor.
| anonymous enum |
| M_DELETE | Indicates that <close> deletes the Tasks. Don't change this value without updating the same enum in class ACE_Module... |
| ACE_Stream<>::ACE_Stream | ( | void * | arg = 0, |
|
| ACE_Module< ACE_SYNCH_USE > * | head = 0, |
|||
| ACE_Module< ACE_SYNCH_USE > * | tail = 0 | |||
| ) |
Create a Stream consisting of <head> and <tail> as the Stream head and Stream tail, respectively. If these are 0 then the <ACE_Stream_Head> and <ACE_Stream_Tail> are used, respectively. <arg> is the value past in to the <open> methods of the tasks.
| ACE_Stream<>::~ACE_Stream | ( | void | ) | [virtual] |
Close down the stream and release all the resources.
| int ACE_Stream<>::close | ( | int | flags = M_DELETE |
) | [virtual] |
Close down the stream and release all the resources.
| int ACE_Stream<>::control | ( | ACE_IO_Cntl_Msg::ACE_IO_Cntl_Cmds | cmd, | |
| void * | args | |||
| ) | [virtual] |
Send control message down the stream.
| ACE_BEGIN_VERSIONED_NAMESPACE_DECL void ACE_Stream<>::dump | ( | void | ) | const [virtual] |
Dump the state of an object.
| ACE_Module< ACE_SYNCH_USE > * ACE_Stream<>::find | ( | const ACE_TCHAR * | mod | ) | [virtual] |
Find a particular ACE_Module.
| int ACE_Stream<>::get | ( | ACE_Message_Block *& | mb, | |
| ACE_Time_Value * | timeout = 0 | |||
| ) | [virtual] |
Read the message <mb> that is stored in the stream head. Wait for upto <timeout> amount of absolute time for the operation to complete (or block forever if <timeout> == 0).
| ACE_BEGIN_VERSIONED_NAMESPACE_DECL ACE_INLINE ACE_Module< ACE_SYNCH_USE > * ACE_Stream<>::head | ( | void | ) | [virtual] |
Return current stream head.
| int ACE_Stream<>::insert | ( | const ACE_TCHAR * | prev_name, | |
| ACE_Module< ACE_SYNCH_USE > * | mod | |||
| ) | [virtual] |
Insert a new module <mod> below the named module <prev_name>.
| int ACE_Stream<>::link | ( | ACE_Stream< ACE_SYNCH_USE > & | ) | [virtual] |
Create a pipe between two Streams.
| int ACE_Stream<>::link_i | ( | ACE_Stream< ACE_SYNCH_USE > & | ) | [private] |
Actually perform the linking of two Streams (must be called with locks held).
| int ACE_Stream<>::open | ( | void * | arg, | |
| ACE_Module< ACE_SYNCH_USE > * | head = 0, |
|||
| ACE_Module< ACE_SYNCH_USE > * | tail = 0 | |||
| ) | [virtual] |
Create a Stream consisting of <head> and <tail> as the Stream head and Stream tail, respectively. If these are 0 then the <ACE_Stream_Head> and <ACE_Stream_Tail> are used, respectively. <arg> is the value past in to the <open> methods of the tasks.
| int ACE_Stream<>::pop | ( | int | flags = M_DELETE |
) | [virtual] |
are invoked to cleanup the tasks.
| int ACE_Stream<>::push | ( | ACE_Module< ACE_SYNCH_USE > * | mod | ) | [virtual] |
Add a new module <mod> right below the Stream head. The <open()> hook methods of the <ACE_Tasks> in this <ACE_Module> are invoked to initialize the tasks.
| int ACE_Stream<>::push_module | ( | ACE_Module< ACE_SYNCH_USE > * | , | |
| ACE_Module< ACE_SYNCH_USE > * | = 0, |
|||
| ACE_Module< ACE_SYNCH_USE > * | = 0 | |||
| ) | [private] |
Must a new module onto the Stream.
| int ACE_Stream<>::put | ( | ACE_Message_Block * | mb, | |
| ACE_Time_Value * | timeout = 0 | |||
| ) | [virtual] |
Send the message <mb> down the stream, starting at the Module below the Stream head. Wait for upto <timeout> amount of absolute time for the operation to complete (or block forever if <timeout> == 0).
| int ACE_Stream<>::remove | ( | const ACE_TCHAR * | mod, | |
| int | flags = M_DELETE | |||
| ) | [virtual] |
Remove the named module <mod> from the stream. This bypasses the strict LIFO ordering of <push> and <pop>.

| int | flags = M_DELETE | |||

Return current stream tail.
| int ACE_Stream<>::top | ( | ACE_Module< ACE_SYNCH_USE > *& | mod | ) | [virtual] |
Return the top module on the stream (right below the stream head).
| int ACE_Stream<>::unlink | ( | void | ) | [virtual] |
Remove a pipe formed between two Streams.
| int ACE_Stream<>::unlink_i | ( | void | ) | [private] |
Actually perform the unlinking of two Streams (must be called with locks held).
| ACE_INLINE int ACE_Stream<>::wait | ( | void | ) | [virtual] |
Synchronize with the final close of the stream.
