I am making my first bukkit plugin. I would like to programmatically create a YAML file that represents a HashMap
. How can I set and get this data structure?
The HashMap
parameters look like <Signature, Location>
, where Signature
is my class that stores 4 integers, and Location
is org.bukkit.Location
I think I would like the YAML file to look like this, but I am not sure if this structure is best:
MyPlugin:
ListOfData:
- signature: [1,2,3,4] # this is a unique set of 4 integers
location: [122,64,254] # non-unique set of 3 integers
- signature: [4,2,1,2]
location: [91,62,101]
- signature: [3,3,1,3]
location: [190,64,321]
Signature
can be modified as necessary, and I can create a wrapper for Location
if necessary.
Thanks!
This is a suggested solution. I don't know if it is the best way...:) You may want to consider this as your yaml structure:
MyPlugin:
ListOfData:
'[1,2,3,4]': '[122,64,254]'
'[4,2,1,2]': '[91,62,101]'
'[3,3,1,3]': '[190,64,321]'
anothersignature:anotherlocation
...
This will let you read the "ListOfData" in using the normal technique for reading hash map from a YAMLConfiguration (see below).
You'll have to treat the incoming information from the file as a HashMap of <String, String> and do any translation (e.g. turn 122,64,254 into a location) you need from there.
For reading a HashMap:
this.getConfig().getConfigurationSection("path.to.map").getValues(false)
For writing a HashMap (saveConfig() will still need to be called to write to disk):
this.getConfig().createSection("path.to.map", MyMap)
There's some details and subtleties here, its worth reading these carefully (same page, but different non-contiguous sections):
