Interface Command

public interface Command

Represents an executable path and set of arguments that may be run by an execution system.

Each Command is associated with an ExecutionSystem that can execute it and implements system-dependent behavior, like argument escaping.

Implementations of this interface are immutable.

Method Detail

getExecutionSystem

ExecutionSystem getExecutionSystem()

Returns the ExecutionSystem associated with this command.

getExecutable

String getExecutable()

Returns this command's executable. The value may be a string representation of a path or a simple name.

getArguments

ImmutableList<String> getArguments()

Returns the arguments of this command.

Each element in the list corresponds to a single logical argument passed to this command's executable. The arguments are the unmodified string representations of the objects provided when this command was constructed. The execution system may modify these arguments to escape system-dependent special characters when this command is executed.

toString

String toString()

Returns a human-readable string representation of this command. The string is similar to the character sequence entered in a terminal to manually execute this command, but may leave out necessary escape characters.

Overrides:

toString in class Object

equals

boolean equals(Object obj)

Tests this Command for equality with another object.

If the other object is not a Command or is a Command associated with a different execution system, this method returns false.

Otherwise, two commands are equal if they have the same executable and the same arguments.

This method satisfies the general contract of the Object.equals method.

Overrides:

equals in class Object

hashCode

int hashCode()

Returns a hash code for this Command.

The hash code combines the hash codes of the executable and the arguments list.

This method satisfies the general contract of the Object.hashCode method.

Overrides:

hashCode in class Object
