Interface Echo.Interface<R>

Type Parameters:

R - the generic return type for all command signature methods to support different implementor types; the methods of a command factory for instance returns a command instance; command builders can also implement this interface, but their methods return the builder itself enabling for chained method invocation to create joined commands

All Superinterfaces:

CommandInterface<R>

All Known Subinterfaces:

Unix4jCommandBuilder

All Known Implementing Classes:

DefaultUnix4jCommandBuilder, EchoFactory

Enclosing class:

Echo

public static interface Echo.Interface<R>
extends CommandInterface<R>

Interface defining all method signatures for the "echo" command.

Method Summary

Modifier and Type	Method and Description
R	echo(EchoOptions options, String... strings) Writes any of the specified strings, separated by single blank (' ') characters to the standard output suppressing the trailing line ending if the -n option is specified.
R	echo(EchoOptions options, String string) Writes the specified string followed by a newline character to the standard output suppressing the trailing line ending if the -n option is specified.
R	echo(String... args) Writes any of the specified strings, separated by single blank (' ') characters to the standard output suppressing the trailing line ending if the "-n" option is specified.

Method Detail

echo

R echo(String... args)

Writes any of the specified strings, separated by single blank (' ') characters to the standard output suppressing the trailing line ending if the "-n" option is specified.

Parameters:

args - String arguments defining the options for the command and the strings to be written to the output. Options can be specified by acronym (with a leading dash "-") or by long name (with two leading dashes "--").

Returns:

the generic type <R> defined by the implementing class; the command itself returns no value and writes its result to the standard output; see class level parameter comments for more details

echo

R echo(EchoOptions options,
       String string)

Writes the specified string followed by a newline character to the standard output suppressing the trailing line ending if the -n option is specified.

Parameters:

options - Options for the echo command.

string - A string to be written to standard output.

Returns:

the generic type <R> defined by the implementing class; the command itself returns no value and writes its result to the standard output; see class level parameter comments for more details

echo

R echo(EchoOptions options,
       String... strings)

Writes any of the specified strings, separated by single blank (' ') characters to the standard output suppressing the trailing line ending if the -n option is specified.

Parameters:

options - Options for the echo command.

strings - Strings to be written to standard output, separated by single blank characters.

Returns:

the generic type <R> defined by the implementing class; the command itself returns no value and writes its result to the standard output; see class level parameter comments for more details
