# Data Structures
|
|
|
|
## Classes
|
|
- **MemberInfo**
|
|
a class that encapsulates the data contained in a `<top_level_object>` or `<member>` xml element
|
|
- **EnumInfo**
|
|
a class that encapsulates the data contained in an `<enumeration>` xml element
|
|
|
|
## Lists
|
|
- **allInstances**
|
|
a list of `MemberInfo`s
|
|
- **rootInstances**
|
|
another list of `MemberInfo`s
|
|
|
|
## Hash Maps
|
|
- **typeHashMap**
|
|
a hash map whose keys are strings and whose values are lists of `MemberInfo`s
|
|
- **enumHashMap**
|
|
a hash map whose keys are strings and whose values are `EnumInfo`s
|
|
|
|
# Logic Pseudo-Code
|
|
|
|
```
|
|
for each topLevelObject in (xml elements of type <top_level_object>):
|
|
info = new MemberInfo(topLevelObject)
|
|
allInstances.add(info)
|
|
rootInstances.add(info)
|
|
|
|
for each clazz in (xml elements of type <class>):
|
|
memberList = new List()
|
|
typeHashMap[clazz.name] = memberList
|
|
for each member in (xml element of type <member>):
|
|
info = new MemberInfo(member)
|
|
allInstances.add(info)
|
|
memberList.add(info)
|
|
|
|
for each enum in (xml elements of type <enumeration>):
|
|
enumHashMap[enum.name] = new EnumInfo(enum)
|
|
|
|
for each instance in allInstances:
|
|
instance.children = typeHashMap[instance.type] // one of these
|
|
instance.enumeration = enumHashMap[instance.type] // will be NULL
|
|
```
|

# Walking the Tree
|
|
The entire variable hierarchy can be obtained via a pre-order depth-first traversal of `rootInstances`. The other data structures are now redundant and can be discarded. |
