An attribute set is a map containing an entry for each parameter. The default parameter (unnamed quoted string) is named _DEFAULT in the map.

An attribute set is a hash containing an entry for each parameter. The default parameter (unnamed quoted string) is named _DEFAULT in the hash.
  Attributes declared later in the string will override those of the same name defined earlier. The one exception to this is the _DEFAULT key, where

As well as standard TWiki syntax (parameter values double-quoted) it also parses single-quoted values, unquoted spaceless values, spaces around the =, and commas as well as spaces separating values, though none of these alternatives is advertised in documentation and the extended syntax can be turned off by passing the 'strict' parameter

As well as the default TWiki syntax (parameter values double-quoted) this class also parses single-quoted values, unquoted spaceless values, spaces around the =, and commas as well as spaces separating values. The extended syntax has to be enabled by passing the $friendly parameter

StaticMethod extractValue () -> $string

Legacy support, formerly known as extractNameValuePair. This static method uses context information to determine how a value string is to be parsed. For example, if you have an attribute string like this:

"abc def="ghi" jkl" def="qqq"

then call extractValue( "def" ), it will return "ghi".

ObjectMethod get ($key) -> $value

$key Attribute to get
Get an attr value from the map.

Synonymous with $attrs->{$key}. Retained mainly for compatibility with the old AttrsContrib .
