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.

Method Detail

buildExpression

protected AbstractExpression buildExpression(AbstractExpression parent,
                                             WordParser wordParser,
                                             java.lang.String word,

                                             boolean tolerant)
Creates the actual AbstractExpression this factory manages.

Specified by:
buildExpression in class AbstractLiteralExpressionFactory
Parameters:
parent - The parent expression
wordParser - The text to parse based on the current position of the cursor
word - The current word to parse
expression - 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
