DOH (Dave's Object Hack)
|
|
|
|
Overview:
|
|
---------
|
|
DOH is a small C library that provides a number of simple yet powerful
|
|
data structures for building flexible applications. The data
|
|
structures are built around a dynamic type model in which any given
|
|
object is allowed to support one or more classes of operations.
|
|
|
|
Common Operations (for all types)
|
|
---------------------------------
|
|
Delete(obj) Decrease the reference count and destroy if zero
|
|
Copy(obj) Make a copy of an object.
|
|
Str(obj) Create a string representation of obj.
|
|
Data(obj) Return pointer to raw data in an object
|
|
Len(obj) Length of an object
|
|
Hash(obj) Hash value (used for mapping)
|
|
Cmp(obj1,obj2) Compare two objects.
|
|
Name(obj) Return the object name
|
|
First(obj) Return first object (iterator)
|
|
Next(obj) Return next object
|
|
|
|
Mapping Operations (for hash table behavior)
|
|
--------------------------------------------
|
|
Getattr(hash,key) Get an attribute
|
|
Setattr(hash,key,value) Set an attribute
|
|
Delattr(hash,key) Delete an attribute
|
|
Firstkey(hash,key) Get first key
|
|
Nextkey(hash,key) Get next key
|
|
Getattrf(hash,key,format,...) Formatted attribute get
|
|
Setattrf(hash,key,format,...) Formatted attribute set
|
|
|
|
Sequence Operations
|
|
-------------------
|
|
Getitem(list,index) Get an item
|
|
Setitem(list,index,val) Set an item
|
|
Delitem(list,index,val) Delete an item
|
|
Insert(list,index,val) Insert an item
|
|
Append(list,val) Append to end
|
|
|
|
File Operations
|
|
---------------
|
|
Read(obj,buffer,len) Read data
|
|
Write(obj,buffer,len) Write data
|
|
Getc(obj) Get a character
|
|
Putc(ch,obj) Put a character
|
|
Ungetc(ch,obj) Put character back on input stream
|
|
Seek(obj,offset,whence) Seek
|
|
Tell(obj) Return file pointer
|
|
Printf(obj,format,...) Printf
|
|
Close(obj) Close
|
