.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Log::Message::Item is a class that generates generic Log items.
These items are stored on a Log::Message stack, so see the Log::Message
manpage about details how to retrieve them.
.PP
You should probably not create new items by yourself, but use the
storing mechanism provided by Log::Message.
.PP
However, the accessors and handlers are of interest if you want to do
fine tuning of how your messages are handled.
.PP
The accessors and methods are described below, the handlers are
documented in the Log::Message::Handlers manpage.
.SH "Methods and Accessors"
.IX Header "Methods and Accessors"
.Sh "remove"
.IX Subsection "remove"
Calling remove will remove the object from the stack it was on, so it
will not show up any more in subsequent fetches of messages.
.PP
You can still call accessors and handlers on it however, to handle it
as you will.
.Sh "id"
.IX Subsection "id"
Returns the internal \s-1ID\s0 of the item. This may be useful for comparing
since the \s-1ID\s0 is incremented each time a new item is created.
Therefore, an item with \s-1ID\s0 4 must have been logged before an item with
\&\s-1ID\s0 9.
.Sh "when"
.IX Subsection "when"
Returns the timestamp of when the message was logged
.Sh "message"
.IX Subsection "message"
The actual message that was stored
.Sh "level"
.IX Subsection "level"
The severity type of this message, as well as the name of the handler
that was called upon storing it.
.Sh "tag"
.IX Subsection "tag"
Returns the identification tag that was put on the message.
.Sh "shortmess"
.IX Subsection "shortmess"
Returns the equivalent of a \f(CW\*(C`Carp::shortmess\*(C'\fR for this item.
See the \f(CW\*(C`Carp\*(C'\fR manpage for details.
.Sh "longmess"
.IX Subsection "longmess"
Returns the equivalent of a \f(CW\*(C`Carp::longmess\*(C'\fR for this item, which
is essentially a stack trace.
See the \f(CW\*(C`Carp\*(C'\fR manpage for details.
.Sh "parent"
.IX Subsection "parent"
Returns a reference to the Log::Message object that stored this item.
This is useful if you want to have access to the full stack in a
handler.
