I have a JTable which is loaded from a data-structure using table model.The data-structure is of the format
NavigableMap<Float,NavigableMap<Float,Boolean>>.An example data is:
Table Format: Range f1,v1 f2,v2 f3,v3 f4,v4 12.1-30.2 30,true 32,false 45,true 50,false 30.2-45.6 30,true 32.4,true 45,true 50.1,true
The above data format is represented in the DS as
DS Format: Key Value 12.1 <<30,true>,<32,false>,<45,true>,<50,false>> 30.2 <<30,true>,<32.4,true>,<45,true>,<50.1,true>> 45.6 null
I have managed to represent the above given data in Jtable using table-model.Once the data is loaded from the DS to the table I have to allow user edit.Now this is where I have problem.My doubt is whether is should keep the data structure synchronized with the changes in the table or should i recreate the DS from the table once the user finish editing and then replace it with the old one.
More over I need to validate the data(for example from above - Suppose the user want's to edit the value 30.1.He should only be allowed to enter values between 12.1 and 45.6.Since data the tables are string's (once loaded) I'm planning to use regex and key-listener and consume all user key presses which doesn't match the regex and values which doesn't come within the range.I'm not sure is this is a good idea or what are implications.I would like to get some suggestions on this.
