LightMutexDirect

from panda3d.core import LightMutexDirect
class LightMutexDirect

Bases: DTOOL_SUPER_BASE

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

/**

  • 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.
