Package icyllis.modernui.util

Class DataSet

java.lang.Object
icyllis.modernui.util.DataSet
All Implemented Interfaces:
Parcelable, Map<String,Object>
public final class DataSet extends Object implements Map<String,Object>, Parcelable
A DataSet encapsulates mappings from string keys to primitive values (includes String and UUID values). The specified data types can safely be persisted to and restored from local storage and network in binary form. Unsupported I/O data types can also be put into the data set for in-memory operations, and they will be silently ignored during I/O.

A DataSet object can be put into other data sets (exclude itself) to construct a tree structure. Additionally, an array structure (exposed in List) is also supported, where elements are backed by ArrayList.

The implementation of this class is a linked hash map, which is fast and small-footprint.
