Function that will be called with the OutputStream to
which all input to the process must be written. This will
be called in a newly spawned thread.
Function that will be called with the InputStream
from which all normal output of the process must be
read from. This will be called in a newly spawned
thread.
Function that will be called with the InputStream from
which all error output of the process must be read from.
This will be called in a newly spawned thread.
Indicates whether the newly spawned threads that
will run processOutput, processError and
writeInput should be marked as daemon threads.

true if !(this == that), false otherwise.
Equivalent to x.hashCode except for boxed numeric types and null.
Equivalent to x.hashCode except for boxed numeric types and null.
For numerics, it returns a hash value which is consistent
with value equality: if two value type instances compare
as true, then ## will produce the same hash value for each
of them.
For null returns a hashcode where null.hashCode throws a
NullPointerException.

The expression x == that is equivalent to if (x eq null) that eq null else x.equals(that).

true if the receiver object is equivalent to the argument; false otherwise.
Cast the receiver object to be of type T0.
Cast the receiver object to be of type T0.
Note that the success of a cast at runtime is modulo Scala's erasure semantics.
Therefore the expression 1.asInstanceOf[String] will throw a ClassCastException at
runtime, while the expression List(1).asInstanceOf[List[String]] will not.
In the latter example, because the type argument is erased as part of compilation it is
not possible to check whether the contents of the list are of the requested type.

ClassCastException if the receiver object is not an instance of the erasure of type T0.
Create a copy of the receiver object.
Indicates whether the newly spawned threads that

Creates a new ProcessIO, with daemonizeThreads true.
Tests whether the argument (arg0) is a reference to the receiver object (this).

The eq method implements an equivalence relation on
non-null instances of AnyRef, and has three additional properties:
x and y of type AnyRef, multiple invocations of
x.eq(y) consistently returns true or consistently returns false.x of type AnyRef, x.eq(null) and null.eq(x) returns false.null.eq(null) returns true. When overriding the equals or hashCode methods, it is important to ensure that their behavior is
consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they
should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).

The details of when and if the finalize method is invoked, as
well as the interaction between finalize and non-local returns
and exceptions, are all platform dependent.

Format strings are as for String.format
(@see java.lang.String.format).

The hashCode method for reference types.
Test whether the dynamic type of the receiver object is T0.
Test whether the dynamic type of the receiver object is T0.
Note that the result of the test is modulo Scala's erasure semantics.
Therefore the expression 1.isInstanceOf[String] will return false, while the
expression List(1).isInstanceOf[List[String]] will return true.
In the latter example, because the type argument is erased as part of compilation it is
not possible to check whether the contents of the list are of the specified type.
true if the receiver object is an instance of erasure of type T0; false otherwise.

This class is used to control the I/O of every scala.sys.process.Process. The functions used to create it will be called with the process streams once it has been started. It might not be necessary to use
ProcessIOdirectly -- scala.sys.process.ProcessBuilder can return the process output to the caller, or use a scala.sys.process.ProcessLogger which avoids direct interaction with a stream. One can even use the factories atBasicIOto create aProcessIO, or use its helper methods when creating one's ownProcessIO.When creating a
ProcessIO, it is important to close all streams when finished, since the JVM might use system resources to capture the process input and output, and will not release them unless the streams are explicitly closed.ProcessBuilderwill callwriteInput,processOutputandprocessErrorin separate threads, and if daemonizeThreads is true, they will all be marked as daemon threads.Failure to close the passed streams may result in resource leakage.
