Package jline.console.completer

Class ArgumentCompleter

java.lang.Object

jline.console.completer.ArgumentCompleter

All Implemented Interfaces:

Completer

public class ArgumentCompleter
extends java.lang.Object
implements Completer

A Completer implementation that invokes a child completer using the appropriate separator argument. This can be used instead of the individual completers having to know about argument parsing semantics.

Since:

2.3

Nested Class Summary

Nested Classes

Modifier and Type	Class	Description
static class	ArgumentCompleter.AbstractArgumentDelimiter	Abstract implementation of a delimiter that uses the ArgumentCompleter.AbstractArgumentDelimiter.isDelimiter(java.lang.CharSequence, int) method to determine if a particular character should be used as a delimiter.
static interface	ArgumentCompleter.ArgumentDelimiter	The ArgumentCompleter.ArgumentDelimiter allows custom breaking up of a String into individual arguments in order to dispatch the arguments to the nested Completer.
static class	ArgumentCompleter.ArgumentList	The result of a delimited buffer.
static class	ArgumentCompleter.WhitespaceArgumentDelimiter	ArgumentCompleter.ArgumentDelimiter implementation that counts all whitespace (as reported by Character.isWhitespace(char)) as being a delimiter.

Constructor Summary

Constructors

Constructor	Description
ArgumentCompleter(java.util.List<Completer> completers)	Create a new completer with the default ArgumentCompleter.WhitespaceArgumentDelimiter.
ArgumentCompleter(ArgumentCompleter.ArgumentDelimiter delimiter, java.util.Collection<Completer> completers)	Create a new completer with the specified argument delimiter.
ArgumentCompleter(ArgumentCompleter.ArgumentDelimiter delimiter, Completer... completers)	Create a new completer with the specified argument delimiter.
ArgumentCompleter(Completer... completers)	Create a new completer with the default ArgumentCompleter.WhitespaceArgumentDelimiter.

Method Summary

Modifier and Type	Method	Description
int	complete(java.lang.String buffer, int cursor, java.util.List<java.lang.CharSequence> candidates)	Populates candidates with a list of possible completions for the buffer.
java.util.List<Completer>	getCompleters()
ArgumentCompleter.ArgumentDelimiter	getDelimiter()
boolean	isStrict()	Returns whether a completion at argument index N will success if all the completions from arguments 0-(N-1) also succeed.
void	setStrict(boolean strict)	If true, a completion at argument index N will only succeed if all the completions from 0-(N-1) also succeed.

Constructor Detail

ArgumentCompleter

public ArgumentCompleter(ArgumentCompleter.ArgumentDelimiter delimiter,
                         java.util.Collection<Completer> completers)

Create a new completer with the specified argument delimiter.

Parameters:

delimiter - The delimiter for parsing arguments

completers - The embedded completers

ArgumentCompleter

public ArgumentCompleter(ArgumentCompleter.ArgumentDelimiter delimiter,
                         Completer... completers)

Create a new completer with the specified argument delimiter.

Parameters:

delimiter - The delimiter for parsing arguments

completers - The embedded completers

ArgumentCompleter

public ArgumentCompleter(Completer... completers)

Create a new completer with the default ArgumentCompleter.WhitespaceArgumentDelimiter.

Parameters:

completers - The embedded completers

ArgumentCompleter

public ArgumentCompleter(java.util.List<Completer> completers)

Create a new completer with the default ArgumentCompleter.WhitespaceArgumentDelimiter.

Parameters:

completers - The embedded completers

Method Detail

setStrict

public void setStrict(boolean strict)

If true, a completion at argument index N will only succeed if all the completions from 0-(N-1) also succeed.

isStrict

public boolean isStrict()

Returns whether a completion at argument index N will success if all the completions from arguments 0-(N-1) also succeed.

Returns:

True if strict.

complete

public int complete(java.lang.String buffer,
                    int cursor,
                    java.util.List<java.lang.CharSequence> candidates)

Description copied from interface: Completer

Populates candidates with a list of possible completions for the buffer. The candidates list will not be sorted before being displayed to the user: thus, the complete method should sort the List before returning.

Specified by:

complete in interface Completer

Parameters:

buffer - The buffer

cursor - The current position of the cursor in the buffer

candidates - The List of candidates to populate

Returns:

The index of the buffer for which the completion will be relative
