All Implemented Interfaces:

NodeVisitor<SoyNode,Boolean>
```
public class IsComputableAsJsExprsVisitor
extends AbstractReturningSoyNodeVisitor<Boolean>
```
Visitor to determine whether the output string for the subtree rooted at a given node is computable as the concatenation of one or more JS expressions. If this is false, it means the generated code for computing the node's output must include one or more full JS statements.
Precondition: MsgNode should not exist in the tree.
Important: This class is in ApiCallScope because it memoizes results that are reusable for the same parse tree. If we change the parse tree between uses of the scoped instance, then the results may not be correct. (In that case, we would need to take this class out of ApiCallScope and rewrite the code somehow to still take advantage of the memoized results to the extent that they remain correct.)
TODO(user): This should no longer be necessary after CodeChunk migration. Rip it all out.
