Macro Definition Documentation

JUCE_ASSERT_MESSAGE_MANAGER_EXISTS

#define JUCE_ASSERT_MESSAGE_MANAGER_EXISTS   jassert (juce::MessageManager::getInstanceWithoutCreating() != nullptr);

This macro is used to catch unsafe use of functions which expect to not be called outside the lifetime of the MessageManager.

JUCE_ASSERT_MESSAGE_MANAGER_IS_LOCKED

#define JUCE_ASSERT_MESSAGE_MANAGER_IS_LOCKED   jassert (juce::MessageManager::existsAndIsLockedByCurrentThread());

This macro is used to catch unsafe use of functions which expect to only be called on the message thread, or when a MessageManagerLock is in place. It will also fail if you try to use the function before the message manager has been created, which could happen if you accidentally invoke it during a static constructor.

JUCE_ASSERT_MESSAGE_THREAD

#define JUCE_ASSERT_MESSAGE_THREAD   jassert (juce::MessageManager::existsAndIsCurrentThread());

This macro is used to catch unsafe use of functions which expect to only be called on the message thread. It will also fail if you try to use the function before the message manager has been created, which could happen if you accidentally invoke it during a static constructor.
