public ExecutableWrapper(ConfiguredExecutable<?> executable,
                         java.lang.String workDirectory)

Method Detail

call

public ConfiguredExecutable<?> call()
                             throws java.io.IOException

It is vital that output and error streams are captured immediately for this call() to succeed. Thus each instance if ExecutableWrapper has 2 its own thread ready to capture the output. If executor could not execute capture immediately this could lead to the call method to stale, as execution could not proceed without output being captured. Every call to call() method will use 2 threads
