Utility classes for VHAL implementation
This directory stores utility classes for VHAL implementation. Vendor
implementation could use utility classes from common folder in their
VHAL implementation.
common
Defines common utility libraries.
ConcurrentQueue
Provides a thread-safe concurrent queue object. Useful for adding object to a queue in one thread (usually binder thread) and handle the objects in a separate handler thread.
ParcelableUtils
Provides functions to convert between a regular parcelable and a
LargeParcelabe.
A LargeParcelable is a parcelable that marshals the payload
into a shared memory file if the payload is too large to pass across binder.
It is used to pass large data across binder. Before sending the data, VHAL
impl should convert a regular parcelabe to a LargeParcelable. After receving
data, VHAL impl should convert a LargeParcelable back to regular parcelabe.
PendingRequestPool
Defines A class for managing pending requests and automatically call timeout callback if the request timed-out.
PropertyUtils
Defines some useful constants.
RecurrentTimer
Defines a thread-safe recurrent timer that can call a function periodically.
VehicleHalTypes
Provides a header file that includes many commonly used header files. Useful when you are using multiple types defined in VHAL interface.
VehicleObjectPool
Defines a reusable in-memory pool for VehiclePropValue.
VehiclePropertyStore
Defines an in-memory map for storing vehicle properties. Allows easier insert, delete and lookup.
VehicleUtils
Defines many useful utility functions.
test
Defines utility libraries for test only.
