Styles are typically
implemented for each entity type in ACA. So wall has a wall style and windows
has windows style, so on and so forth. Styles are containers of settings for
that object type. So when we create a wall style and create walls with that
style, all these walls will contains the behavior. |

In the API, Styles
derive from dictionary record. Style dictionary is a collection of
objects that contain the dictionary
records. These are derived from AutoCAD dictionary object. So there will be
dictionary wall style that is the container for wall styles and they are all
stored in dictionaries. The constructor will take a parameter and it has to
know the database. Most of them exposes the get standard style and so any
time we open a new drawing (even if we do not use any template to open a
drawing), if we draw a wall, it will still initialize and create a default
wall style. This is because the wall needs to know what style it is in order
to display properly. So getStandardStyle will get the style even in cases
when no style has been initialized before. This method helps gain access to
default standard style for that type. |

Since they are
essentially dictionaries, they expose properties and behavior like
dictionaries. For example, they expose - |
|
Record property
which is a collection of style ids. |
|
GetAT will get a
specific style and throw an exception if it does not find any. |

NamesInUse – helps
in checking if your suggested name conflicts with existing style names and so
is a good approach to check before creating a new one. |
