Interface ToRowFromChange<R extends RowAssert>

Type Parameters:

R - The class of a assertion on a row (an sub-class of RowAssert).

All Known Subinterfaces:

OriginWithColumnsAndRowsFromChange, OriginWithValuesFromColumn, OriginWithValuesFromRow

All Known Implementing Classes:

AbstractAssertWithOriginWithColumnsAndRowsFromChange, AbstractAssertWithValues, ChangeAssert, ChangeColumnAssert, ChangeColumnValueAssert, ChangeRowAssert, ChangeRowValueAssert

public interface ToRowFromChange<R extends RowAssert>

Defines methods to navigate to a Row from a Change.

The different methods return an assertion on one row RowAssert.

These methods exists when navigating (at the beginning assertThat()) from changes.

As shown in the diagram below, it is possible to call the method to navigate to a RowAssert from :

• a change (ChangeAssert)
• a column of a change (ChangeColumnAssert)
• a value of a column of a change (ChangeColumnValueAssert)
• a row of a change (ChangeRowAssert)
• a value of a row of a change (ChangeRowValueAssert)

It is important to keep in mind that the methods are executed from the point of view of the last instance with assertion methods on a change (ChangeAssert).
So all the lines of code below are equivalent : they point on the row at end point.

 
 assertThat(changes).change().rowAtEndPoint()......;                                                    // Point directly on the row at end point
 // Use the returnToOrigin() method of AbstractAssertWithOrigin to return on the change and access to the row at end point
 assertThat(changes).change().rowAtStartPoint().returnToOrigin().rowAtEndPoint()......;
 assertThat(changes).change().rowAtStartPoint().rowAtEndPoint()......;                                  // Same as precedent but returnToOrigin() is implicit
 assertThat(changes).change().column().rowAtEndPoint()......;                                           // The method can be call from a column
 assertThat(changes).change().column().value().rowAtEndPoint()......;
 assertThat(changes).change().column(1).value().rowAtEndPoint()......;
 // Equivalent to the precedent but with the use of the returnToOrigin() method of AbstractAssertWithOrigin
 assertThat(changes).change().column(1).value().returnToOrigin().returnToOrigin().rowAtEndPoint()......;
