acquire

Tries to become the owner of the specified context.

If some other thread is the owner of the context, returns false immediately. Ownership is properly recursive: the owner can require ownership again and will release ownership when release is called as many times as acquire.

You must be the owner of a context before you can call prepare, query, check , dispatch, release.

Since 2.76 this can be null to use the global-default main context.

Parameters:

this	a MainContext (if null, the global-default main context will be used)

Returns:

true if the operation succeeded, and this thread is now the owner of this .
