public final class ArgumentListArgument
extends Argument

This class defines an argument whose values are intended to be argument strings as might be provided to a command-line application (e.g., "--arg1 arg1value --arg2 --arg3 arg3value"). Instances of this argument will have their own argument parser that may be used to process the argument strings. This type of argument may not be particularly useful for use in command-line applications, but may be used in other applications that may use arguments in other ways.

ArgumentListArgument

public ArgumentListArgument(@Nullable
 Character shortIdentifier,
 @Nullable
 String longIdentifier,
 @NotNull
 String description,
 @NotNull
 ArgumentParser parser)
                     throws ArgumentException

Creates a new argument list argument with the provided information. It will not be required, will permit at most one occurrence, and will use a default placeholder.

Parameters:

shortIdentifier - The short identifier for this argument. It may not be null if the long identifier is null.

longIdentifier - The long identifier for this argument. It may not be null if the short identifier is null.

description - A human-readable description for this argument. It must not be null.

parser - The argument parser that will be used to process values provided for this argument.

Throws:

ArgumentException - If there is a problem with the definition of this argument.

ArgumentListArgument

public ArgumentListArgument(@Nullable
 Character shortIdentifier,
 @Nullable
 String longIdentifier,
 boolean isRequired,
 int maxOccurrences,
 @Nullable
 String valuePlaceholder,
 @NotNull
 String description,
 @NotNull
 ArgumentParser parser)
                     throws ArgumentException

Creates a new argument list argument with the provided information.

Parameters:

shortIdentifier - The short identifier for this argument. It may not be null if the long identifier is null.

longIdentifier - The long identifier for this argument. It may not be null if the short identifier is null.

isRequired - Indicates whether this argument is required to be provided.

maxOccurrences - The maximum number of times this argument may be provided on the command line. A value less than or equal to zero indicates that it may be present any number of times.

valuePlaceholder - A placeholder to display in usage information to indicate that a value must be provided. It may be null if a default placeholder should be used.

description - A human-readable description for this argument. It must not be null.

parser - The argument parser that will be used to process values provided for this argument.

Throws:

ArgumentException - If there is a problem with the definition of this argument.

Method Details

getCleanParser

@NotNull
public ArgumentParser getCleanParser()

Retrieves a "clean" copy of the argument parser that will be used to process values provided for this argument.

Returns:

A "clean" copy of the argument parser that will be used to process values provided for this argument.

addValue

protected void addValue(@NotNull
 String valueString)
                 throws ArgumentException

Adds the provided value to the set of values for this argument. This method should only be called by the argument parser.

Specified by:

addValue in class Argument

Parameters:

valueString - The string representation of the value.

Throws:

ArgumentException - If the provided value is not acceptable, if this argument does not accept values, or if this argument already has the maximum allowed number of values.

getValueParsers

@NotNull
public List<ArgumentParser> getValueParsers()

Retrieves the list of argument parsers that have been used to process values provided to this argument.

Returns:

The list of argument parsers that have been used to process values provided to this argument.

getValueStrings

@NotNull
public List<String> getValueStrings()

Retrieves the list of the string representations of the values provided to this argument.

Returns:

The list of the string representations of the values provided to this argument.

getValueStringRepresentations

@NotNull
public List<String> getValueStringRepresentations(boolean useDefault)

Retrieves a list containing the string representations of the values for this argument, if any. The list returned does not necessarily need to include values that will be acceptable to the argument, but it should imply what the values are (e.g., in the case of a boolean argument that doesn't take a value, it may be the string "true" or "false" even if those values are not acceptable to the argument itself).

Specified by:

getValueStringRepresentations in class Argument

Parameters:

useDefault - Indicates whether to use any configured default value if the argument doesn't have a user-specified value.

Returns:

A string representation of the value for this argument, or an empty list if the argument does not have a value.

hasDefaultValue

protected boolean hasDefaultValue()

Indicates whether this argument has one or more default values that will be used if it is not provided on the command line.

Specified by:

hasDefaultValue in class Argument

Returns:

true if this argument has one or more default values, or false if not.

getDataTypeName

@NotNull
public String getDataTypeName()

Retrieves a concise name of the data type with which this argument is associated.

Specified by:

getDataTypeName in class Argument

Returns:

A concise name of the data type with which this argument is associated.

getValueConstraints

@NotNull
public String getValueConstraints()

Retrieves a human-readable string with information about any constraints that may be imposed for values of this argument.

Overrides:

getValueConstraints in class Argument

Returns:

A human-readable string with information about any constraints that may be imposed for values of this argument, or null if there are none.

reset

protected void reset()

Resets this argument so that it appears in the same form as before it was used to parse arguments. Subclasses that override this method must call super.reset() to ensure that all necessary reset processing is performed.

Overrides:

reset in class Argument

getCleanCopy

@NotNull
public ArgumentListArgument getCleanCopy()

Creates a copy of this argument that is "clean" and appears as if it has not been used in the course of parsing an argument set. The new argument will have all of the same identifiers and constraints as this parser.

Specified by:

getCleanCopy in class Argument

Returns:

The "clean" copy of this argument.

addToCommandLine

protected void addToCommandLine(@NotNull
 List<String> argStrings)

Updates the provided list to add any strings that should be included on the command line in order to represent this argument's current state.

Specified by:

addToCommandLine in class Argument

Parameters:

argStrings - The list to update with the string representation of the command-line arguments.

toString

public void toString(@NotNull
 StringBuilder buffer)

Appends a string representation of this argument to the provided buffer.

Specified by:

toString in class Argument

Parameters:

buffer - The buffer to which the information should be appended.
