Constructor Details

LongParser

public LongParser(long min,
 long max)

Construct a new long parser

Parameters:

min - Minimum acceptable value

max - Maximum acceptable value

Method Details

longParser

@API(status=STABLE)
public static <C> @NonNull ParserDescriptor<C,Long> longParser()

Creates a new long parser using DEFAULT_MINIMUM and DEFAULT_MAXIMUM as the limits.

Type Parameters:

C - the command sender type

Returns:

the created parser

longParser

@API(status=STABLE)
public static <C> @NonNull ParserDescriptor<C,Long> longParser(long minValue)

Creates a new long parser using DEFAULT_MAXIMUM as the maximum value.

Type Parameters:

C - the command sender type

Parameters:

minValue - the minimum value accepted by the parser

Returns:

the created parser

longParser

@API(status=STABLE)
public static <C> @NonNull ParserDescriptor<C,Long> longParser(long minValue,
 long maxValue)

Creates a new long parser.

Type Parameters:

C - the command sender type

Parameters:

minValue - the minimum value accepted by the parser

maxValue - the maximum value accepted by the parser

Returns:

the created parser

longComponent

@API(status=STABLE)
public static <C>
@NonNull CommandComponent.Builder<C,Long> longComponent()

Returns a CommandComponent.Builder using longParser() as the parser.

Type Parameters:

C - the command sender type

Returns:

the component builder

parse

public @NonNull ArgumentParseResult<Long> parse(@NonNull CommandContext<C> commandContext,
 @NonNull CommandInput commandInput)

Description copied from interface: ArgumentParser

Attempts to parse the input into an object of type ArgumentParser.

This method may be called when a command chain is being parsed for execution (using CommandExecutor.executeCommand(Object, String)) or when a command is being parsed to provide context for suggestions (using SuggestionFactory.suggest(Object, String)). It is possible to use CommandContext.isSuggestions()} to see what the purpose of the parsing is. Particular care should be taken when parsing for suggestions, as the parsing method is then likely to be called once for every character written by the command sender.

This method should never throw any exceptions under normal circumstances. Instead, if the parsing for some reason cannot be done successfully ArgumentParseResult.failure(Throwable) should be returned. This then wraps any exception that should be forwarded to the command sender.

The parser is assumed to be completely stateless and should not store any information about the command sender or the command context. Instead, information should be stored in the CommandContext.

Specified by:

parse in interface ArgumentParser<C,Long>

Parameters:

commandContext - Command context

commandInput - Command Input

Returns:

Parsed command result

hasMax

public boolean hasMax()

Description copied from class: NumberParser

Returns whether this parser has a maximum value set.

In other words, whether the maximum of it's NumberParser.range() is different than the default maximum value.

Specified by:

hasMax in class NumberParser<C,Long,LongRange>

Returns:

whether the parser has a maximum set

hasMin

public boolean hasMin()

Description copied from class: NumberParser

Returns whether this parser has a minimum value set.

In other words, whether the minimum of it's NumberParser.range() is different than the default minimum value.

Specified by:

hasMin in class NumberParser<C,Long,LongRange>

Returns:

whether the parser has a minimum set

stringSuggestions

public @NonNull Iterable<@NonNull String> stringSuggestions(@NonNull CommandContext<C> commandContext,
 @NonNull CommandInput input)

Description copied from interface: BlockingSuggestionProvider.Strings

Returns the suggestions for the given input.

The input parameter contains all sender-provided input that has not yet been consumed by the argument parsers. If the component that the suggestion provider is generating suggestions for consumes multiple tokens the suggestion provider might receive a CommandInput instance containing multiple tokens. CommandInput.lastRemainingToken() may be used to extract the part of the command that is currently being completed by the command sender.

Specified by:

stringSuggestions in interface BlockingSuggestionProvider.Strings<C>

Parameters:

commandContext - Command context

input - Input string

Returns:

List of suggestions
