.SH "Detailed Description"
.PP 
inotify watch class 

It holds information about the inotify watch on a particular inode.
.PP
If the INOTIFY_THREAD_SAFE is defined this class is thread-safe. 
.SH "Constructor & Destructor Documentation"
.PP 
.SS "InotifyWatch::InotifyWatch (const std::string & rPath, int32_t uMask, bool fEnabled = \fCtrue\fP)\fC [inline]\fP"
.PP
Constructor. 
.PP
Creates an inotify watch. Because this watch is inactive it has an invalid descriptor (-1).
.PP
\fBParameters:\fP
.RS 4
\fIrPath\fP watched file path 
.br
\fIuMask\fP mask for events 
.br
\fIfEnabled\fP events enabled yes/no 
.RE
.PP

.SS "InotifyWatch::~InotifyWatch ()\fC [inline]\fP"
.PP
Destructor. 
.PP
.SH "Member Function Documentation"
.PP 
.SS "void InotifyWatch::__Disable ()\fC [private]\fP"
.PP
Disables the watch (due to removing by the kernel). 
.PP
This method must be called after receiving an event. It ensures the watch object is consistent with the kernel data. 
.SS "int32_t InotifyWatch::GetDescriptor () const\fC [inline]\fP"
.PP
Returns the watch descriptor. 
.PP
\fBReturns:\fP
.RS 4
watch descriptor; -1 for inactive watch 
.RE
.PP

.SS "\fBInotify\fP* InotifyWatch::GetInotify ()\fC [inline]\fP"
.PP
Returns the appropriate inotify class instance. 
.PP
\fBReturns:\fP
.RS 4
inotify instance 
.RE
.PP

.SS "uint32_t InotifyWatch::GetMask () const\fC [inline]\fP"
.PP
Returns the watch event mask. 
.PP
\fBReturns:\fP
.RS 4
event mask 
.RE
.PP

.SS "const std::string& InotifyWatch::GetPath () const\fC [inline]\fP"
.PP
Returns the watched file path. 
.PP
\fBReturns:\fP
.RS 4
file path 
.RE
.PP

.SS "bool InotifyWatch::IsEnabled () const\fC [inline]\fP"
.PP
Checks whether the watch is enabled. 
.PP
\fBReturns:\fP
.RS 4
true = enables, false = disabled 
.RE
.PP

.SS "bool InotifyWatch::IsRecursive () const\fC [inline]\fP"
.PP
Checks whether the watch is recursive. 
.PP
A recursive watch monitors a directory itself and all its subdirectories. This watch is a logical object which may have many underlying kernel watches.
.PP
\fBReturns:\fP
.RS 4
currently always false (recursive watches not yet supported) 
.RE
.PP
\fBAttention:\fP
.RS 4
Recursive watches are currently NOT supported. They are planned for future versions. 
.RE
.PP

.SS "void InotifyWatch::SetEnabled (bool fEnabled)  throw (\fBInotifyException\fP)"
.PP
Enables/disables the watch. 
.PP
If the watch is active (added to an instance of \fBInotify\fP) this method may fail due to unsuccessful re-setting the watch in the kernel.
.PP
Re-setting the current state has no effect.
.PP
\fBParameters:\fP
.RS 4
\fIfEnabled\fP set enabled yes/no
.RE
.PP
\fBExceptions:\fP
.RS 4
\fI\fBInotifyException\fP\fP thrown if enabling/disabling fails 
.RE
.PP

.SS "void InotifyWatch::SetMask (uint32_t uMask)  throw (\fBInotifyException\fP)"
.PP
Sets the watch event mask. 
.PP
If the watch is active (added to an instance of \fBInotify\fP) this method may fail due to unsuccessful re-setting the watch in the kernel.
.PP
\fBParameters:\fP
.RS 4
\fIuMask\fP event mask
.RE
.PP
\fBExceptions:\fP
.RS 4
\fI\fBInotifyException\fP\fP thrown if changing fails
