Throws:

IOException

supportsAnonPipeRead

public boolean supportsAnonPipeRead()

Description copied from interface: IProcessBuilderCore

Whether the process builder can read from anonymous pipes. Docker containers can only bind-mount named pipes but not anonymous pipes. When building pipelines, this flag is used to avoid needless intermediate anon pipes where named ones can be used directly. For pipelines, this is the value of the first process builder.

supportsAnonPipeWrite

public boolean supportsAnonPipeWrite()

Description copied from interface: IProcessBuilderCore

Whether the process builder can write to an anonymous pipe. Docker containers can only bind-mount named pipes but not anonymous pipes. When building pipelines, this flag is used to avoid needless intermediate anon pipes where named ones can be used directly. For pipelines, this is the value of the last process builder.

supportsDirectNamedPipe

public boolean supportsDirectNamedPipe()

Groups only support direct named pipes if there is only a single member that accepts a direct named pipe.

accessesStdIn

public boolean accessesStdIn()

Description copied from interface: IProcessBuilderCore

Whether the configured command will read from stdin. Used to avoid generation of needless named or anon pipes such as in "echo foo | echo bar": where the second link does not read the data from the prior link.
