public final class UpdateItemStateFieldPathExpressionFactory
- extends AbstractLiteralExpressionFactory
This UpdateItemStateFieldPathExpressionFactory
is meant to handle the parsing of a
portion of the query when it's expected to be a state field path. By default a word without a dot
would be parsed as an identification variable but for the left side of the update item assignment,
a single word is a state field path expression.

- Creates the actual

this factory manages.
- Specified by:
buildExpression
in class AbstractLiteralExpressionFactory
- Parameters:
parent
- The parent expressionwordParser
- The text to parse based on the current position of the cursorword
- The current word to parseexpression
- During the parsing, it is possible the first part of
an expression was parsed which needs to be used as a sub-expression of the newly created
expression
- Returns:
- A new
AbstractExpression
representing the given word
