.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Via \fIWeather::Com::AirPressure\fR one can access the barometric
pressure and its tendency.
.PP
This class will \fBnot\fR be updated automatically with each call to one
of its methods. You need to call the \f(CW\*(C`pressure()\*(C'\fR method of the parent
object again to update your object.
.SH "CONSTRUCTOR"
.IX Header "CONSTRUCTOR"
You usually would not construct an object of this class yourself. 
This is implicitely done when you call the \f(CW\*(C`pressure()\*(C'\fR method 
of one current conditions or forecast object.
.SH "METHODS"
.IX Header "METHODS"
.Sh "\fIpressure()\fP"
.IX Subsection "pressure()"
Returns the barometric pressure.
.Sh "tendency([$language])"
.IX Subsection "tendency([$language])"
Returns the tendency of the barometric pressure.
.PP
This attribute is \fIdynamic language enabled\fR.
