Getmetacount (function)

Returns the number of times an attribute or a field is encountered in the current metadata hierarchy. It can also be used to ver-

ify whether a field or attribute exists by comparing the returned value to zero. Note that attributes can only appear once, and

thus can only yield two possible values, either zero or one.

Syntax

getmetacount(name: string[, flags: integer, path: string]) integer

Arguments

name

The name of the metadata value to count.

flags

Optional integer value to define the behavior of the command.The default behavior uses 0. The flag value to enter should be

the sum of all desired flags. (Eg: GetAttribute and FailIfNotFound would give a flag value of '5').

Name Value Behavior

GetAttribute 1

Search for the name argument in the attribute instead of

the default field .
