Modifier and Type	Method and Description
`String[]`	`getArgs()` Returns the `<args>` operand value: String arguments defining the options and operands for the command.
`File[]`	`getFiles()` Returns the `<files>` operand value: The input files; relative paths are not resolved (use the string paths argument to enable relative path resolving based on the current working directory).
`WcArguments`	`getForContext(ExecutionContext context)` Returns an arguments object for the given execution context with resolved variables if necessary and possible.
`Input[]`	`getInputs()` Returns the `<inputs>` operand value: The inputs.
`WcOptions`	`getOptions()` Returns the options set containing the selected command options.
`String[]`	`getPaths()` Returns the `<paths>` operand value: Path names of the input files; wildcards * and ? are supported; relative paths are resolved on the basis of the current working directory.
`boolean`	`isArgsSet()` Returns true if the `<args>` operand has been set.
`boolean`	`isChars()` Returns true if the `--chars` option is set.

`boolean`	`isLines()` Returns true if the `--lines` option is set.
`boolean`	`isPathsSet()` Returns true if the `<paths>` operand has been set.
`boolean`	`isWords()` Returns true if the `--words` option is set.
`void`	`setFiles(File... files)` Sets `<files>`: The input files; relative paths are not resolved (use the string paths argument to enable relative path resolving based on the current working directory).
`void`	`setInputs(Input... inputs)` Sets `<inputs>`: The inputs.
`void`	`setPaths(String[] paths)` Sets `<paths>`: Path names of the input files; wildcards * and ? are supported; relative paths are resolved on the basis of the current working directory.

- Constructor Detail
  - WcArguments
```
public WcArguments()
```
    Constructor to use if no options are specified.
  - WcArguments
```
public WcArguments(WcOptions options)
```
    Constructor with option set containing the selected command options.
    
    Parameters:
    
    options - the selected options
    
    Throws:
    
    NullPointerException - if the argument is null
  - WcArguments
```
public WcArguments(String... args)
```
    Constructor string arguments encoding options and arguments, possibly also containing variable expressions.
    
    Parameters:
    
    args - string arguments for the command
    
    Throws:
    
    NullPointerException - if args is null
- Method Detail
  - getOptions
```
public WcOptions getOptions()
```
    Returns the options set containing the selected command options. Returns an empty options set if no option has been selected.
    
    Returns:
    
    set with the selected options
  - getForContext
```
public WcArguments getForContext(ExecutionContext context)
```
    Description copied from interface: Arguments
    
    Returns an arguments object for the given execution context with resolved variables if necessary and possible. If variables are defined in this arguments instance, a new arguments instance is created with values instead of variables for those variables that are defined in the specified context object. If this arguments instance uses no variables, this arguments instance is simply returned.
    If variables are present, they are resolved if such a variable is defined in the VariableContext returned by context.getVariableContext(). Values are converted if necessary with the ValueConverters returned by context.getValueConverterFor(Class).
    
    Specified by:
    
    getForContext in interface Arguments<WcArguments>
    
    Parameters:
    
    context - the execution context providing access to variables and converters
    
    Returns:
    
    an arguments object with resolved variables where possible
  - getPaths
```
public String[] getPaths()
```
    Returns the <paths> operand value: Path names of the input files; wildcards * and ? are supported; relative paths are resolved on the basis of the current working directory.
    
    Returns:

    Throws:
    
    IllegalStateException - if this operand has never been set
  - isPathsSet
```
public boolean isPathsSet()
```
    Returns true if the <paths> operand has been set.
    Note that this method returns true even if null was passed to the setPaths(String[]) method.
    
    Returns:
    
    true if the setter for the <paths> operand has been called at least once
  - setPaths
```
public void setPaths(String[] paths)
```
    Sets <paths>: Path names of the input files; wildcards * and ? are supported; relative paths are resolved on the basis of the current working directory.
    
    Parameters:
    
    paths - the value for the <paths> operand
  - getFiles
```
public File[] getFiles()
```
    Returns the <files> operand value: The input files; relative paths are not resolved (use the string paths argument to enable relative path resolving based on the current working directory).
