extends
AnyRefConsole
object implements functionality for
printing Scala values on the terminal. There are also functions
for reading specific values. Console
also defines
constants for marking up text on ANSI terminals.Value Summary | |

Method Summary | |
def
|
flush
: Unit
Flush the output stream. This function is required when partial
output (i.e. output not terminated by a new line character) has
to be made visible on the terminal.
|
def
|
format (text : java.lang.String, args : Any*) : Unit |
def
|
in : java.io.BufferedReader |
def
|
out : java.io.PrintStream |
def
|
print
(obj : Any) : Unit
Print an object on the terminal.
|
def
|
printf
(text : java.lang.String, args : Any*) : Unit
Prints its arguments as a formatted string, based on a string pattern (in a fashion similar to printf in C).
The interpretation of the formatting patterns is described in
|
def
|
println
(x : Any) : Unit
Print out an object followed by a new line character.
|
def
|
println
: Unit
Print a new line character on the terminal.
|
def
|
readBoolean
: Boolean
Read a boolean value from the terminal.
|
def
|
readByte
: Byte
Read a byte value from the terminal.
|
def
|
readChar
: Char
Read a char value from the terminal.
|
def
|
readDouble
: Double
Read a double value from the terminal.
|
def
|
readFloat
: Float
Read a float value from the terminal.
|
def
|
readInt
: Int
Read an int value from the terminal.
|
def
|
readLine
(text : java.lang.String, args : Any*) : java.lang.String
Print a formatted text and read a full line from the terminal
|
def
|
readLine
: java.lang.String
Read a full line from the terminal.
|
def
|
readLong
: Long
Read an int value from the terminal.
|
def
|
readShort
: Short
Read a short value from the terminal.

def
|
readf
(format : java.lang.String) : List[Any]
Read in some structured input, specified by a format specifier.
See class
java.text.MessageFormat for details of
the format specification. |
def
|
readf1
(format : java.lang.String) : Any
Read in some structured input, specified by a format specifier.
Opposed to
readf , this function only returns the
first value extracted from the input according to the format
specification. |

Read in some structured input, specified by a format specifier.
Opposed to
readf , this function only returns the
first two values extracted from the input according to the format
specification. |

(format : java.lang.String) : (Any, Any, Any)
Read in some structured input, specified by a format specifier.
Opposed to
readf , this function only returns the
first three values extracted from the input according to the format
specification. |
def
|

(reader : java.io.Reader) : Unit
Set the default input stream.
|
def
|

(in : java.io.InputStream) : Unit
Set the default input stream.
|
def
|
setOut

of execution of one thunk.

of execution of one thunk.
|
def
