The only part of the implementation that bothers me is the static method. >Finally, each parameters class would implement a static method: That might become tedious to maintain that code, and also error-prone. Of course generics can also be error-prone, and are not too simple to maintain. If only we had a way to combine; make so that users can easily write code using auto-complete, IDE, etc, in an intuitive way, and in a way that we don't have any risks in our side (or very low risk of bugs/hard to maintain code)... -- This is an automated message from the Apache Git Service.

Kinoshita > Priority: Major > Labels: github > Fix For: 1.0-alpha3 > > Time Spent: 9h 40m > Remaining Estimate: 0h > > Currently options for image I/O are defined as Maps. The leads to the problem > that our code has to validate parameter types when they are used: > {code:java} > final Object value = params.get(PARAM_KEY_COMPRESSION); > if (value != null) { > if (!(value instanceof Number)) { > throw new ImageWriteException( > "Invalid compression parameter, must be numeric: " > + value); > } > compression = ((Number) value).intValue(); > } > {code} > This can be simplified if we define a Parameters class that provides > additional methods like {{public int getInt(String key)}}. The implementation > could then look up the value from the map through an exception if it is null > or not a number. -- This message was sent by Atlassian Jira (v8.3.4#803005)
