Analysis

Overview

The navigation between chained frames now cannot be implemented because of internal issues. After this task there will be no visual result but the navigation will be possible to be implemented.

Task requirements

• The HotPos class holds a reference to the text it belongs to, but after manual chaining this text is changed and the new position does not belong to the text. That's why the HotPos class will no longer hold the text, but all the elemOp's of the text(the whole history of the text). This will make possible the implementation of the navigation.
• The ImmHotText class will no longer hold the last changed interval, it's subsingle interval and its previous text. All those will be replaced by ImmList<ElemOp> (the history of the text). This will make it easy to make new HotPoses and will reduce the code.
• The subText will no longer be as its parent text with another subInterval but a new ImmHoText made by removing the first and the last intervals of the parent text(example: text: 1234567 subText(0,2) the result is: 12).
• Those changes will remove some of the ImmHotText functionality and will reduce the code. The code quality will be improved.

Task result

the result should be code.

Implementation idea

• Remove the text from the HotPos and add ImmList<ElemOp>.
• Remove prevText, subSingleInterval, lastOperation, lastChangedInterval from the ImmHotText and add ImmList<ElemOp>.
• Tests will be provided.

• Change getIndex, subText and other related functions of the ImmHotText.
