- liquibase.command.CommandArgumentDefinition<DataType>

All Implemented Interfaces:

Comparable<CommandArgumentDefinition<?>>
```
public class CommandArgumentDefinition<DataType>
extends Object
implements Comparable<CommandArgumentDefinition<?>>
```
Defines a known, type-safe argument for a specific CommandStep. Includes metadata about the argument such as a description, if it is required, a default value, etc.
Because this definition is tied to a specific step, multiple steps in a pipeline can define arguments of the same name.

See Also:

for constructing new instances.

protected CommandArgumentDefinition(String name,
                                    Class<DataType> type)
```
- Method Detail
  - getName
```
public String getName()
```
    The name of the argument. Must be camelCase alphanumeric.
  - getAliases
```
public SortedSet<String> getAliases()
```
    Aliases for the argument. Must be camelCase alphanumeric.
  - getDescription
```
public String getDescription()
```
    The description of the argument. Used in generated help documentation.
  - getDataType
```
public Class<DataType> getDataType()
```
    The datatype this argument will return.
  - isRequired
```
public boolean isRequired()
```
    Whether this argument is required. Exposed as a separate setting for help doc purposes. validate(CommandScope) will ensure required values are set.
  - getSupersededBy
```
public CommandArgumentDefinition<?> getSupersededBy()
```
  - setSupersededBy
```
public void setSupersededBy(CommandArgumentDefinition<?> supersededBy)
```
  - getHidden
```
public boolean getHidden()
```
    Hidden arguments are ones that can be called via integrations, but should not be normally shown in help to users.
  - getDefaultValue
```
public DataType getDefaultValue()
```
    The default value to use for this argument
  - getDefaultValueDescription
```
public String getDefaultValueDescription()
```
    A description of the default value. Defaults to String.valueOf(Object) of getDefaultValue() but can be explicitly with CommandArgumentDefinition.Building.defaultValue(Object, String).
  - getValueConverter
```
public ConfigurationValueConverter<DataType> getValueConverter()
```
    Function for converting values set in underlying ConfigurationValueProviders into the type needed for this command.
  - getValueObfuscator
```
public ConfigurationValueObfuscator<DataType> getValueObfuscator()
```
    Used when sending the value to user output to protect secure values.
  - validate
```
public void validate(CommandScope commandScope)
              throws CommandValidationException
```
    Validates that the value stored in the given CommandScope is valid.
    
    Throws:
    
    CommandValidationException - if the stored value is not valid.
  - compareTo
```
public int compareTo(CommandArgumentDefinition<?> o)
```
    Specified by:
    
    compareTo in interface Comparable<DataType>
  - equals
```
public boolean equals(Object o)
```
    Overrides:
    
    equals in class Object
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
