Using Input/Output (I/O) Actors

SALSA provides three actors supporting asynchronous I/O. One is an input service (standardInput), and the other two are output services (standardOutput and standardError). Since they are actors, they are used with message passing.

standardOutput provides the following message handlers:

• print(boolean p)
• print(byte p)
• print(char p)
• print(double p)
• print(float p)
• print(int p)
• print(long p)
• print(Object p)
• print(short p)
• println(boolean p)
• println(byte p)
• println(char p)
• println(double p)
• println(float p)
• println(int p)
• println(long p)
• println(Object p)
• println(short p)
• println()

standardError provides the following message handlers:

• print(boolean p)
• print(byte p)
• print(char p)
• print(double p)
• print(float p)
• print(int p)
• print(long p)
• print(Object p)
• print(short p)
• println(boolean p)
• println(byte p)
• println(char p)
• println(double p)
• println(float p)
• println(int p)
• println(long p)
• println(Object p)
• println(short p)
• println()

standardInput provides only one message handler in current SALSA release:

• String readLine()
