Package org.apache.tools.ant

Interface ArgumentProcessor

public interface ArgumentProcessor

Processor of arguments of the command line.

Arguments supported by third party code should not conflict with Ant core ones. It is then recommended to chose specific 'enough' argument name, avoiding for instance one letter arguments. By the way, if there any conflict, Ant will take precedence.

Since:

1.9

void	prepareConfigure(Project project, List<String> args)	If some arguments matched with readArguments(String[], int), this method is called just before the project being configured
void	printUsage(PrintStream writer)	Print the usage of the supported arguments
int	readArguments(String[] args, int pos)	Read the arguments from the command line at the specified position

Method Details

int readArguments(String[] args,
 int pos)

Read the arguments from the command line at the specified position

If the argument is not supported, returns -1. Else, the position of the first argument not supported.

Parameters:

args - String[]

pos - int

Returns:

int

handleArg

boolean handleArg(List<String> args)

If some arguments matched with readArguments(String[], int), this method is called after all arguments were parsed. Returns true if Ant should stop there, ie the build file not parsed and the project should not be executed.

Parameters:

args - List<String>

Returns:

boolean

prepareConfigure

void prepareConfigure(Project project,
 List<String> args)

If some arguments matched with readArguments(String[], int), this method is called just before the project being configured

Parameters:

project - Project

args - List<String>

handleArg

boolean handleArg(Project project,
 List<String> arg)

Handle the arguments with readArguments(String[], int), just after the project being configured. Returns true if Ant should stop there, ie the build file not parsed and the project should not be executed.

Parameters:

project - Project
