Method Detail

getMaxReentrants

public static int getMaxReentrants()

Returns the maximum number of write() method reentrants a thread is allowed to made. This is related to possible write()->onComplete()->write()->... chain, which may grow infinitely and cause StackOverflow. Using maxWriteReentrants value it's possible to limit such a chain.

Returns:

the maximum number of write() method reentrants a thread is allowed to make.

getWriteReentrant

public static Writer.Reentrant getWriteReentrant()

Returns the current write reentrants counter. Might be useful, if developer wants to use custom notification mechanism, based on on Writer.canWrite(org.glassfish.grizzly.Connection) and various write methods.

Returns:

current reentrants counter

get

public int get()

Returns the value of the reentrants counter for the current thread.

inc

public boolean inc()

Increments the reentrants counter by one.

Returns:

true if the counter (after incrementing) didn't reach getMaxReentrants() limit, or false otherwise.

dec

public boolean dec()

Decrements the reentrants counter by one.

Returns:

true if the counter (after decrementing) didn't reach getMaxReentrants() limit, or false otherwise.

isMaxReentrantsReached

public boolean isMaxReentrantsReached()

Returns true, if max number of write->completion-handler reentrants has been reached for the passed Writer.Reentrant object, and next write will happen in the separate thread.

Returns:

true, if max number of write->completion-handler reentrants has been reached for the passed Writer.Reentrant object, and next write will happen in the separate thread.
