 f2 tp            // Prints: C:\Temp\Test2.txt

 f2.readString tp // Prints: Foo

Delete file

Check if exists

Usually returns true, unless was deleted just before

File extension

Returns the part of file name after last period

  val p = J.Path("C:", "Temp", "Test.txt")

  val f: J.File = p.fileMake

  f.path tp       // Prints: C:\Temp\Test.txt

  f.name tp       // Prints: Test.txt

  f.extension tp  // Prints: txt

Last updated time

Returns Time when this was last modified

Move file

Returns new File

 val p = J.Path("C:", "Temp", "Test.txt")

 val f1: J.File = p.fileMake.^(_.writeString("Foo"))

 val f2: J.File = f1.move(p.parent + "Test2.txt")

 f2 tp            // Prints: C:\Temp\Test2.txt

 f2.readString tp // Prints: Foo

Name

Last name without prior path $example

Create input

Opens J.Input to this file

Create output

Opens J.Output to this file

Path

Returns J.Path to this $example

Read as String

Reads this file as String

Full code = openInput.asText.readAllAndClose

File size

Returns file ByteCount

  val p = J.Path("C:", "Temp", "Test.txt")

  val f: J.File = p.fileMake

  f.writeString("ABC" * 1000)

  f.size tp // Prints: 3.0kB

Creates temporary file

Creates new temporary file with this file as base

if App.^.TempPath? is available, this will be the directory, otherwise this file directory will be used

Temporary file name will be `this.name' plus '.temp' or '.temp1' or '.temp2' or '.temp3' or etc. if exists

 val p = J.Path("C:", "Temp", "Test.txt")

 val f: J.File = p.fileMake

 f.temp tp // Prints: C:\Temp\Test.txt.temp

 f.temp tp // Prints: C:\Temp\Test.txt.temp1

 f.temp tp // Prints: C:\Temp\Test.txt.temp2

Write String

Writes String to this file, overwriting prior data

Full code =

 openOutput.asText.writeAllAndClose(s)

Type to Info

Override this method to provide type standard Info implementation

Void check

Override this method to define which instances of this type are void

By default this method always returns false

If type supports void instances, then following inmpelentation should be added in most cases:

 implicit inline def xxRequest(inline v: \/) : <type> = <return void>
