```
    Description copied from interface: Document
    
    Obtain a clone of this document, but with the supplied fields replaced.
    
    Specified by:
    
    with in interface Document
    
    Parameters:
    fieldName - the name of the file that should be changed; may be null
    value - the new value for the field
    
    Returns:
    the clone of this document with the change fields, or this document if there are no changes

    the clone of this document with transformed fields, or this document if the transformer changed none of the values
  - withVariablesReplaced
```
public Document withVariablesReplaced(Properties properties)
```
    Description copied from interface: Document
    Obtain a clone of this document, but with all variables in string field values replaced with the referenced values from the supplied properties.
    Variables may appear anywhere within a string value, and multiple variables can be used within the same value. Variables take the form:
```
    variable := '${' variableNames [ ':' defaultValue ] '}'
    
    variableNames := variableName [ ',' variableNames ]
    
    variableName := /* any characters except ',' and ':' and '}'
    
    defaultValue := /* any characters except
 
```
    Note that variableName is the name used to look up the Properties property.
    Notice that the syntax supports multiple variables. The logic will process the variables from let to right, until an existing System property is found. And at that point, it will stop and will not attempt to find values for the other variables.
    Specified by:
    
    withVariablesReplaced in interface Document
    
    Parameters:
    properties - the properties keyed by variable name
    
    Returns:
    the clone of this document with variables in fields string values replaced with values from the properties object, or this document if no variables were found
    See Also:
    Document.withVariablesReplacedWithSystemProperties(), Document.with(ValueTransformer), SchemaLibrary.convertValues(Document, String)
  - withVariablesReplacedWithSystemProperties
```
public Document withVariablesReplacedWithSystemProperties()
```
    Description copied from interface: Document
    Obtain a clone of this document, but with all variables in string field values replaced with the referenced values from the System properties.
    Variables may appear anywhere within a string value, and multiple variables can be used within the same value. Variables take the form:
```
    variable := '${' variableNames [ ':' defaultValue ] '}'
    
    variableNames := variableName [ ',' variableNames ]
    
    variableName := /* any characters except ',' and ':' and '}'
    
    defaultValue := /* any characters except
 
```
    Note that variableName is the name used to look up a System property via System.getProperty(String).
    Notice that the syntax supports multiple variables. The logic will process the variables from let to right, until an existing System property is found. And at that point, it will stop and will not attempt to find values for the other variables.
    
    Because only string values can contain variables, the resulting values are left as strings. This may not be valid according to the document's JSON Schema, so see SchemaLibrary.convertValues(Document, String) to convert the string values after variable substitution into the expected non-string types.
    Specified by:
    
    withVariablesReplacedWithSystemProperties in interface Document
    
    Returns:
    the clone of this document with variables in fields string values replaced with values from the System properties, or this document if no variables were found
