ParseState (Spring Framework 5.2.12.RELEASE API)

java.lang.Object
- org.springframework.beans.factory.parsing.ParseState

```
public final class ParseState
extends Object
```
Simple ArrayDeque-based structure for tracking the logical position during a parsing process. entries are added to the ArrayDeque at each point during the parse phase in a reader-specific manner.
Calling toString() will render a tree-style view of the current logical position in the parse phase. This representation is intended for use in error messages.
