Method Detail

b2Alloc

public static Pointer b2Alloc(@Cast(value="int32")
                              int size)

Implement this function to use your own memory allocator.

b2Free
```
public static void b2Free(Pointer mem)
```
If you implement b2Alloc, you should also implement this function.

b2SetAllocFreeCallbacks

public static void b2SetAllocFreeCallbacks(b2AllocFunction allocCallback,
                                           b2FreeFunction freeCallback,
                                           Pointer callbackData)

Set alloc and free callbacks to override the default behavior of using malloc() and free() for dynamic memory allocation. Set allocCallback and freeCallback to NULL to restore the default allocator (malloc / free).

b2SetNumAllocs
```
public static void b2SetNumAllocs(@Cast(value="const int32")
                                  int numAllocs)
```
Set the number of calls to b2Alloc minus the number of calls to b2Free. This can be used to disable the empty heap check in b2SetAllocFreeCallbacks() which can be useful for testing.

b2GetNumAllocs
```
@Cast(value="int32")
public static int b2GetNumAllocs()
```
Get number of calls to b2Alloc minus number of calls to b2Free.

b2Log

public static void b2Log(@Cast(value="const char*")
                         BytePointer string)

Logging function.

b2_liquidFunVersion

@MemberGetter
 @Const
 @ByRef
public static b2Version b2_liquidFunVersion()

b2_liquidFunVersionString
```
@Cast(value="const char*")
public static BytePointer b2_liquidFunVersionString()
```
String which identifies the current version of LiquidFun. b2_liquidFunVersionString is used by Google developers to identify which applications uploaded to Google Play are using this library. This allows the development team at Google to determine the popularity of the library. How it works: Applications that are uploaded to the Google Play Store are scanned for this version string. We track which applications are using it to measure popularity. You are free to remove it (of course) but we would appreciate if you left it in.
