Detailed Description

Representation of the class holding a hierarchy of loggers.

Intended use:

Internal

Review Status

Test programs:

tLoggerHolder

Prerequisite

• LogIO

Synopsis

The LoggerHolderRep class is the reference counted implementation of LoggerHolder. See that class for more information.

Motivation

Reference counting was needed to be able to keep a LoggerHolder object after the (ImageInterface) object containing it is gone.

Member Typedef Documentation

const_iterator

typedef LoggerHolderIterator casacore::LoggerHolderRep::const_iterator

Define the STL-style iterators.

Only a const forward iterator is available. It makes it possible to iterate through all messages in the logger.

LoggerHolder logger("log.name", False)
for (LoggerHolder::const_iterator iter=arr.begin();
iter!=arr.end(); iter++) {
cout << iter.message() << endl;
}

STL-style typedefs.

Bool

nullSink

)

Create with a NullSink or MemoryLogSink (default).

Referenced by LoggerHolderRep(), and operator=().

LoggerHolderRep() [2/3]

casacore::LoggerHolderRep::LoggerHolderRep	(	const String &	logTableName,
		Bool	isWritable )

Create with a TableLogSink.

LoggerHolderRep() [3/3]

casacore::LoggerHolderRep::LoggerHolderRep

Member Function Documentation

addParent()

void casacore::LoggerHolderRep::addParent

(

const LoggerHolder &

)

Add a logger from a parent.

append()

void casacore::LoggerHolderRep::append

(

const LoggerHolder &

other

)

Append the entries of the other logger to this one.

begin()

const_iterator casacore::LoggerHolderRep::begin

(

)

const

Get the begin and end iterator object.

clear()

void casacore::LoggerHolderRep::clear

(

)

Clear the log.

It removes the parents and removes all messages from the sink.

doReopen()

void casacore::LoggerHolderRep::doReopen ( )

private

Do the actual reopen.

Referenced by reopen().

end()

const_iterator casacore::LoggerHolderRep::end

(

)

const

flush()

void casacore::LoggerHolderRep::flush

(

)

Flush the log table.

isTempClosed()

Bool casacore::LoggerHolderRep::isTempClosed ( ) const

inline

Is the log table temporarily closed?

Definition at line 278 of file LoggerHolder.h.

References itsIsClosed.

logio()

LogIO & casacore::LoggerHolderRep::logio

(

)

Get access to the logger.

It assumes that it will be used to post a message, so it reopens the log table for read/write if needed).

operator=()

LoggerHolderRep & casacore::LoggerHolderRep::operator=

(

const LoggerHolderRep &

)

Assignment.

It removes the current parents.

References LoggerHolderRep().

parents()

const Block< LoggerHolder > & casacore::LoggerHolderRep::parents ( ) const

inline

Return the block of parents.

Definition at line 298 of file LoggerHolder.h.

References itsParents.

removeParents()

void casacore::LoggerHolderRep::removeParents

(

)

Remove all parents.

reopen()

void casacore::LoggerHolderRep::reopen ( )

inline

Reopen the log table if needed (after a tempClose).

Definition at line 260 of file LoggerHolder.h.

References doReopen(), and itsIsClosed.

reopenRW()

void casacore::LoggerHolderRep::reopenRW

(

)

Reopen a readonly logtable for read/write (if needed).

resync()

void casacore::LoggerHolderRep::resync

(

)

Resync the log table (if needed).

sink()

LogSink & casacore::LoggerHolderRep::sink

(

)

Get access to the log sink (reopen the log table if needed).

It is not assumed you want to write. If you want to do that, you should first call reopenRW() to ensure you can write.

tempClose()

void casacore::LoggerHolderRep::tempClose

(

Bool

closeParents = True

)

Temporarily close all log tables.

By default the possible parent log tables are also closed.

References casacore::True.

unlock()

void casacore::LoggerHolderRep::unlock

(

)

Unlock the log table.
