Expressions Given Row

Expressing values using a "Row Expression" (See Row Expressions on the documentation website.) can occur in the following two types of operations:

• Providing a new value for every selected cell given the row of that cell (Row Expression), for instance in map, add, and insert (using RowExpression).

• Providing a new value for every selected cell given the row of that cell and its previous value (Row Value Expression), for instance in update.with, and convert.notNull (using RowValueExpression).

NOTE:

update with-, convert with- and add-like expressions use AddDataRow instead of DataRow as the DSL's receiver type. This is an extension to RowValueExpression and RowExpression that provides access to the modified/generated value of the preceding row (AddDataRow.newValue).

A Row Expression is similar to a Row Condition but expects a Boolean as result.
