All content below this line refers to {{#multireplace:System.Classes.TCollectionItem|H21=!|H25=%|H28=(|H29=)|H2A=*|H2B=+|H2F=/|H3C=<|H3D==|H3E=>|H5B=[|H5D=]|H5E=^|H7C=|}}.
TCollectionItem represents an item in a collection.
A TCollection holds a group of TCollectionItem objects. TCollectionItems are created and destroyed by TCollection's Add and Clear methods. Each TCollectionItem has a Collection property that points to the TCollection object to which the item belongs.
Objects descending from TCollection can contain objects descending from TCollectionItem. For example, a TDBGridColumns object contains TColumn objects; these two classes are used by TDBGrid to represent grid columns.
