static <E extends java.lang.Throwable> void	runAndWait(ThrowableRunnable<E> action) Executes action inside write action.
static AccessToken	start() Deprecated. Use run(ThrowableRunnable) or compute(ThrowableComputable) instead

execute

@Deprecated
public RunResult<T> execute()

Deprecated. use run(ThrowableRunnable) or compute(ThrowableComputable) or (if really desperate) computeAndWait(ThrowableComputable) instead

Specified by:

execute in class BaseActionRunnable<T>

start

@Deprecated
public static AccessToken start()

Deprecated. Use run(ThrowableRunnable) or compute(ThrowableComputable) instead

run

public static <E extends java.lang.Throwable> void run(ThrowableRunnable<E> action)
                                                throws E extends java.lang.Throwable

Executes action inside write action. Must be called from the EDT.

Throws:

E extends java.lang.Throwable

compute

public static <T,E extends java.lang.Throwable> T compute(ThrowableComputable<T,E> action)
                                                   throws E extends java.lang.Throwable

Executes action inside write action and returns the result. Must be called from the EDT.

Throws:

E extends java.lang.Throwable

run

@Deprecated
protected abstract void run(Result<T> result)
                     throws java.lang.Throwable

Deprecated. use run(ThrowableRunnable) or compute(ThrowableComputable) instead

Specified by:

run in class BaseActionRunnable<T>

Throws:

java.lang.Throwable

runAndWait

public static <E extends java.lang.Throwable> void runAndWait(ThrowableRunnable<E> action)
                                                       throws E extends java.lang.Throwable

Executes action inside write action. If called from outside the EDT, transfers control to the EDT first, executes write action there and waits for the execution end.
CAUTION: if called from outside EDT, please be aware of possible deadlocks (e.g. when EDT is busy) or invalid data (e.g. when something is changed during control transferred to EDT and back).
Instead, please use run(ThrowableRunnable).

Throws:

E extends java.lang.Throwable

computeAndWait

public static <T,E extends java.lang.Throwable> T computeAndWait(ThrowableComputable<T,E> action)
                                                          throws E extends java.lang.Throwable

Executes action inside write action. If called from outside the EDT, transfers control to the EDT first, executes write action there and waits for the execution end.
CAUTION: if called from outside EDT, please be aware of possible deadlocks (e.g. when EDT is busy) or invalid data (e.g. when something is changed during control transferred to EDT and back).
Instead, please use compute(ThrowableComputable).

Throws:

E extends java.lang.Throwable
