Package Summary Overview Summary

### class:ProcessBuilder.Redirect [NONE]
- Enclosing class: ProcessBuilder
      public abstract static class ProcessBuilder.Redirect
      extends Object
Represents a source of subprocess input or a destination of subprocess output. Each `Redirect` instance is one of the following: the special value `Redirect.PIPE` the special value `Redirect.INHERIT` a redirection to read from a file, created by an invocation of `Redirect.from(File)` a redirection to write to a file, created by an invocation of `Redirect.to(File)` a redirection to append to a file, created by an invocation of `Redirect.appendTo(File)` Each of the above categories has an associated unique `Type`. Since: 1.7

### field:PIPE [NONE]
- #### PIPE
      public static final ProcessBuilder.Redirect PIPE
  Indicates that subprocess I/O will be connected to the current Java process over a pipe. This is the default handling of subprocess standard I/O. It will always be true that
       Redirect.PIPE.file() == null &&
       Redirect.PIPE.type() == Redirect.Type.PIPE

### field:INHERIT [NONE]
- #### INHERIT
      public static final ProcessBuilder.Redirect INHERIT
  Indicates that subprocess I/O source or destination will be the same as those of the current process. This is the normal behavior of most operating system command interpreters (shells). It will always be true that
       Redirect.INHERIT.file() == null &&
       Redirect.INHERIT.type() == Redirect.Type.INHERIT

### method:type() [NONE]
- #### type
      public abstract ProcessBuilder.Redirect.Type type()
Returns the type of this `Redirect`. Returns: the type of this `Redirect`

### method:file() [NONE]
- #### file
      public File file()
Returns the `File` source or destination associated with this redirect, or `null` if there is no such file. Returns: the file associated with this redirect, or `null` if there is no such file

### method:from(java.io.File) [NONE]
- #### from
      public static ProcessBuilder.Redirect from(File file)
  Returns a redirect to read from the specified file. It will always be true that
       Redirect.from(file).file() == file &&
       Redirect.from(file).type() == Redirect.Type.READ
Parameters: `file` - The `File` for the `Redirect`. Returns: a redirect to read from the specified file Throws: `NullPointerException` - if the specified file is null

### method:to(java.io.File) [NONE]
- #### to
      public static ProcessBuilder.Redirect to(File file)
  Returns a redirect to write to the specified file. If the specified file exists when the subprocess is started, its previous contents will be discarded. It will always be true that
       Redirect.to(file).file() == file &&
       Redirect.to(file).type() == Redirect.Type.WRITE
Parameters: `file` - The `File` for the `Redirect`. Returns: a redirect to write to the specified file Throws: `NullPointerException` - if the specified file is null

### method:appendTo(java.io.File) [NONE]
- #### appendTo
      public static ProcessBuilder.Redirect appendTo(File file)
  Returns a redirect to append to the specified file. Each write operation first advances the position to the end of the file and then writes the requested data. Whether the advancement of the position and the writing of the data are done in a single atomic operation is system-dependent and therefore unspecified. It will always be true that
       Redirect.appendTo(file).file() == file &&
       Redirect.appendTo(file).type() == Redirect.Type.APPEND
Parameters: `file` - The `File` for the `Redirect`. Returns: a redirect to append to the specified file Throws: `NullPointerException` - if the specified file is null

### method:equals(java.lang.Object) [NONE]
- #### equals
      public boolean equals(Object obj)
Compares the specified object with this `Redirect` for equality. Returns `true` if and only if the two objects are identical or both objects are `Redirect` instances of the same type associated with non-null equal `File` instances. Overrides: `equals` in class `Object` Parameters: `obj` - the reference object with which to compare. Returns: `true` if this object is the same as the obj argument; `false` otherwise. See Also: `Object.hashCode()`, `HashMap`

### method:hashCode() [NONE]
- #### hashCode
      public int hashCode()
Returns a hash code value for this `Redirect`. Overrides: `hashCode` in class `Object` Returns: a hash code value for this `Redirect` See Also: `Object.equals(java.lang.Object)`, `System.identityHashCode(java.lang.Object)`
