Summary

Public methods
`static HashMap<String, String>`	`bundleToStringHashMap(Bundle bundle)`
`static ImmutableMap<String, String>`	`bundleToStringImmutableMap(Bundle bundle)`
`static void`	`ensureClassLoader(@Nullable Bundle bundle)` Sets the application class loader to the given `Bundle` if no class loader is present.
`static ImmutableList<T>`	`<T extends Object> fromBundleList( Function<Bundle, T> fromBundleFunc, List<Bundle> bundleList )` Unbundles a list of `Bundle` instances to a list of objects.
`static SparseArray<T>`	`<T extends Object> fromBundleSparseArray( Function<Bundle, T> fromBundleFunc, SparseArray<Bundle> bundleSparseArray )` Unbundles a `SparseArray` of `Bundle` instances to a `SparseArray` of objects.
`static Bundle`	`getBundleWithDefault(Bundle bundle, String field, Bundle defaultValue)`

Public methods

bundleToStringHashMap

public static HashMap<String, String> bundleToStringHashMap(Bundle bundle)

bundleToStringImmutableMap

public static ImmutableMap<String, String> bundleToStringImmutableMap(Bundle bundle)

ensureClassLoader

public static void ensureClassLoader(@Nullable Bundle bundle)

Sets the application class loader to the given Bundle if no class loader is present.

This assumes that all classes unparceled from bundle are sharing the class loader of BundleCollectionUtil.

fromBundleList

public static ImmutableList<T> <T extends Object> fromBundleList(
    Function<Bundle, T> fromBundleFunc,
    List<Bundle> bundleList
)

Unbundles a list of Bundle instances to a list of objects.

Parameters
`Function<Bundle, T> fromBundleFunc`	Function that specified how to unbundle each item.
`List<Bundle> bundleList`	List of `Bundle` instances to be unbundled.

Returns
`ImmutableList<T>`	The `ImmutableList` of unbundled items.

fromBundleSparseArray

public static SparseArray<T> <T extends Object> fromBundleSparseArray(
    Function<Bundle, T> fromBundleFunc,
    SparseArray<Bundle> bundleSparseArray
)

Unbundles a SparseArray of Bundle instances to a SparseArray of objects.

Parameters
`Function<Bundle, T> fromBundleFunc`	Function that specified how to unbundle each item.
`SparseArray<Bundle> bundleSparseArray`	`SparseArray` of `Bundle` instances to be unbundled.

Returns
`SparseArray<T>`	The `SparseArray` of unbundled items.

getBundleWithDefault

public static Bundle getBundleWithDefault(Bundle bundle, String field, Bundle defaultValue)

getIntegerArrayListWithDefault

public static ArrayList<Integer> getIntegerArrayListWithDefault(
    Bundle bundle,
    String field,
    ArrayList<Integer> defaultValue
)

stringMapToBundle

public static Bundle stringMapToBundle(Map<String, String> map)

toBundleArrayList

public static ArrayList<Bundle> <T extends Object> toBundleArrayList(
    Collection<T> items,
    Function<T, Bundle> toBundleFunc
)

Bundles a collection of objects to an ArrayList of Bundle instances so that the returned list can be put to Bundle using putParcelableArrayList conveniently.

Parameters
`Collection<T> items`	Collection of items to be bundled.
`Function<T, Bundle> toBundleFunc`	Function that specifies how to bundle each item.

Returns
`ArrayList<Bundle>`	The `ArrayList` of bundled items.

toBundleList

public static ImmutableList<Bundle> <T extends Object> toBundleList(List<T> list, Function<T, Bundle> toBundleFunc)

Bundles a list of objects to a list of Bundle instances.

Parameters
`List<T> list`	List of items to be bundled.
`Function<T, Bundle> toBundleFunc`	Function that specifies how to bundle each item.

Returns
`ImmutableList<Bundle>`	The `ImmutableList` of bundled items.

toBundleSparseArray

public static SparseArray<Bundle> <T extends Object> toBundleSparseArray(
    SparseArray<T> items,
    Function<T, Bundle> toBundleFunc
)

Bundles a SparseArray of objects to a SparseArray of Bundle instances so that the returned SparseArray can be put to Bundle using putSparseParcelableArray conveniently.

Parameters
`SparseArray<T> items`	Collection of items to be bundled.
`Function<T, Bundle> toBundleFunc`	Function that specifies how to bundle each item.

Returns
`SparseArray<Bundle>`	The `SparseArray` of bundled items.
