Method Detail

getLowerBound

public int getLowerBound()

Retrieves the smallest value that this argument will be allowed to have.

Returns:

The smallest value that this argument will be allowed to have.

getUpperBound

public int getUpperBound()

Retrieves the largest value that this argument will be allowed to have.

Returns:

The largest value that this argument will be allowed to have.

getDefaultValues

public java.util.List<java.lang.Integer> getDefaultValues()

Retrieves the list of default values for this argument, which will be used if no values were provided.

Returns:

The list of default values for this argument, or null if there are no default values.

addValueValidator

public void addValueValidator(ArgumentValueValidator validator)

Updates this argument to ensure that the provided validator will be invoked for any values provided to this argument. This validator will be invoked after all other validation has been performed for this argument.

Parameters:

validator - The argument value validator to be invoked. It must not be null.

addValue

protected void addValue(java.lang.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.

getValue

public java.lang.Integer getValue()

Retrieves the value for this argument, or the default value if none was provided. If this argument has multiple values, then the first will be returned.

Returns:

The value for this argument, or the default value if none was provided, or null if it does not have any values or default values.

getValues

public java.util.List<java.lang.Integer> getValues()

Retrieves the set of values for this argument, or the default values if none were provided.

Returns:

The set of values for this argument, or the default values if none were provided.

getValueStringRepresentations

public java.util.List<java.lang.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

public java.lang.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

public java.lang.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

public IntegerArgument 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(java.util.List<java.lang.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(java.lang.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.
