LightMutexDirect

from panda3d.core import LightMutexDirect

class LightMutexDirect

Bases:

This class implements a lightweight Mutex by making direct calls to the underlying implementation layer. It doesn’t perform any debugging operations.

Inheritance diagram

acquire()

Grabs the lightMutex if it is available. If it is not available, blocks until it becomes available, then grabs it. In either case, the function does not return until the lightMutex is held; you should then call unlock().

This method is considered const so that you can lock and unlock const lightMutexes, mainly to allow thread-safe access to otherwise const data.

Also see LightMutexHolder.

clear_name()

The lightMutex name is only defined when compiling in DEBUG_THREADS mode.

debug_is_locked() → bool

Returns true if the current thread has locked the LightMutex, false otherwise. This method is only intended for use in debugging, hence the method name; in the LightMutexDirect case, it always returns true, since there’s not a reliable way to determine this otherwise.

get_name() → str

The lightMutex name is only defined when compiling in DEBUG_THREADS mode.

has_name() → bool

The lightMutex name is only defined when compiling in DEBUG_THREADS mode.

output(out: ostream)

This method is declared virtual in LightMutexDebug, but non-virtual in LightMutexDirect.

release()

Releases the lightMutex. It is an error to call this if the lightMutex was not already locked.

This method is considered const so that you can lock and unlock const lightMutexes, mainly to allow thread-safe access to otherwise const data.

set_name(name: str)

The lightMutex name is only defined when compiling in DEBUG_THREADS mode.
