    • pipeTo

      PipelineBuilder<Void> pipeTo(Path command)
      Push the output of this process into the input of another process, returning a new builder for that process. The returned process builder cannot have its input configured, because its input will always come from the output of the process built by this builder. Running the final process in the pipeline will start the entire pipeline. After calling this method, this process builder may no longer be modified or executed; therefore, it must be the last method called when building a pipeline. The character set is not used for this output mode.
      Parameters:
      command - the next stage command (must not be null)
      Returns:
      the new process builder for the next stage (not null)

    • pipeTo

      default PipelineBuilder<Void> pipeTo(Path command, List<String> args)
      Push the output of this process into the input of another process, returning a new builder for that process. The returned process builder may not have its input configured, because its input will always come from the output of the process built by this builder. Running the final process in the pipeline will start the entire pipeline. After calling this method, this process builder may no longer be modified or executed; therefore, it must be the last method called when building a pipeline. The character set is not used for this output mode.
      Parameters:
      command - the next stage command (must not be null)
      args - the next stage arguments (must not be null)
      Returns:
      the new process builder for the next stage (not null)

    • pipeTo

      default PipelineBuilder<Void> pipeTo(Path command, String... args)
      Push the output of this process into the input of another process, returning a new builder for that process. The returned process builder may not have its input configured, because its input will always come from the output of the process built by this builder. Running the final process in the pipeline will start the entire pipeline. After calling this method, this process builder may no longer be modified or executed; therefore, it must be the last method called when building a pipeline. The character set is not used for this output mode.
      Parameters:
      command - the next stage command (must not be null)
