`boolean`	`isReverseOrder()` Returns true if the `--reverseOrder` option is set.
`boolean`	`isTimeSorted()` Returns true if the `--timeSorted` option is set.
`void`	`setFiles(File... files)` Sets `<files>`: The files or directories used as starting point for the listing; relative paths are not resolved (use the string path argument to enable relative path resolving based on the current working directory).
`void`	`setPaths(String... paths)` Sets `<paths>`: The files or directories used as starting point for the listing; wildcards * and ? are supported; relative paths are resolved on the basis of the current working directory.

  - LsArguments
```
public LsArguments()
```
    Constructor to use if no options are specified.
  - LsArguments
```
public LsArguments(LsOptions options)
```
    Constructor with option set containing the selected command options.
    
    Parameters:
    
    options - the selected options
    
    Throws:
    
    NullPointerException - if the argument is null
  - LsArguments
```
public LsArguments(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 LsOptions 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 LsArguments 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<LsArguments>
    
    Parameters:
    
    context - the execution context providing access to variables and converters
    
    Returns:
    
    an arguments object with resolved variables where possible
  - getFiles
```
public File[] getFiles()
```
    Returns the <files> operand value: The files or directories used as starting point for the listing; relative paths are not resolved (use the string path argument to enable relative path resolving based on the current working directory).
    
    Returns:
    
    the <files> operand value (variables are not resolved)
    
    Throws:
    
    IllegalStateException - if this operand has never been set
  - isFilesSet
```
public boolean isFilesSet()
```
    Returns true if the <files> operand has been set.
    Note that this method returns true even if null was passed to the setFiles(java.io.File[]) method.
    
    Returns:
    
    true if the setter for the <files> operand has been called at least once
  - setFiles
```
public void setFiles(File... files)
```
    Sets <files>: The files or directories used as starting point for the listing; relative paths are not resolved (use the string path argument to enable relative path resolving based on the current working directory).
    
    Parameters:
    
    files - the value for the <files> operand
  - getPaths
```
public String[] getPaths()
```
    Returns the <paths> operand value: The files or directories used as starting point for the listing; wildcards * and ? are supported; relative paths are resolved on the basis of the current working directory.

    Throws:
    
    IllegalStateException - if this operand has never been set
  - isPathsSet
```
public boolean isPathsSet()
```
    Returns true if the <paths> operand has been set.
