All content below this line refers to {{#multireplace:System.Classes.TCollection.GetAttr|H21=!|H25=%|H28=(|H29=)|H2A=*|H2B=+|H2F=/|H3C=<|H3D==|H3E=>|H5B=[|H5D=]|H5E=^|H7C=|}}.
Returns the name of a custom attribute that can be retrieved using the GetItemAttr method.
TCollection descendants can associate user-defined attributes with the items in the collection. Each attribute has a name and, for each item in the collection, a value that is a string. The GetAttr method returns the name of an attribute.
Index identifies the attribute whose name is requested. This is a value between 0 and n-1, where n is the value returned by GetAttrCount.
As implemented by TCollection, GetAttr always returns an empty string, because TCollection defines no custom attributes.
