The Object type has the following members:
| Object Equals(Object obj) |
| Determine whether this object is equal to another object |
| Object IfNotNull(Block block) |
| If this object is not null, answer the result of evaluating the block; else answer null |
| Object IfNotNullElse(Block notNullBlock, Block nullBlock) |
| If this object is not null, answer the result of evaluating the first block; else answer the result of evaluating the second block |
| Object IfNull(Block block) |
| If this object is null, answer the result of evaluating the block; else answer null |
| Object IfNullElse(Block nullBlock, Block notNullBlock) |
| If this object is null, answer the result of evaluating the first block; else answer the result of evaluating the second block |
| Object IsNull |
| Answer true if this object is null; else false |
| String ToString |
| Answer this object converted to a string |
| Type Type |
| Answer the Type of this object |
null.IsNull
true
This obviously begs the question, is IsNull the only member which can be called on null? Everything else returns "Error evaluating expression: No such property or function: UndefinedObject.<MemberName>"
Is null a WikiTalkWellKnownObject?
"".IsNull
false
