Class ParseState

java.lang.Object
  extended by org.springframework.beans.factory.parsing.ParseState

public final class ParseState
extends Object

Simple Stack-based structure for tracking the logical position during a parsing process. entries are added to the stack 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.
