```
public final class PropertiesFile
extends Object
```
A properties file.
Represents a properties file together with the ability to parse it from a CharSource. This is similar to Properties but with a simpler format and without extending Map. Duplicate keys are allowed and handled.
The properties file format used here is deliberately simple. There is only one element - key-value pairs.
The key is separated from the value using the '=' symbol. The string ' = ' is searched for before '=' to allow an equals sign to be present in the key, which implies that this string cannot be in either the key or the value. Duplicate keys are allowed. For example 'key = value'. The equals sign and value may be omitted, in which case the value is an empty string.
Keys and values are trimmed. Blank lines are ignored. Whole line comments begin with hash '#' or semicolon ';'. No escape format is available. Lookup is case sensitive.
This example explains the format:
```
  # line comment
  key = value
  month = January
 
```
The aim of this class is to parse the basic format. Interpolation of variables is not supported.

```
public static PropertiesFile of(CharSource source)
```
    Parses the specified source as a properties file.
    This parses the specified character source expecting a properties file format. The resulting instance can be queried for each key and value.
    Properties files sometimes contain a Unicode Byte Order Mark. Callers are responsible for handling this, such as by using UnicodeBom.
    
    Parameters:
    
    source - the properties file resource
    
    Returns:
    
    the properties file
    
    Throws:
    
    UncheckedIOException - if an IO exception occurs
    
    IllegalArgumentException - if the file cannot be parsed
  - of
```
public static PropertiesFile of(PropertySet keyValueMap)
```
    Obtains an instance from a key-value property set.
    
    Parameters:
    
    keyValueMap - the key-value property set
    
    Returns:
    
    the properties file
  - getProperties
```
public PropertySet getProperties()
```
    Gets all the key-value properties of this file.
    The map of key-value properties is exposed by this method.
    
    Returns:
    
    the key-value properties
  - equals
```
public boolean equals(Object obj)
```
    Checks if this file equals another.
    The comparison checks the content.
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    obj - the other section, null returns false
    
    Returns:
    
    true if equal
  - hashCode
```
public int hashCode()
```
    Returns a suitable hash code for the file.
    
    Overrides:
    
    hashCode in class Object
    
    Returns:
    
    the hash code
  - toString
```
public String toString()
```
    Returns a string describing the file.
    
    Overrides:
    
    toString in class Object
    
    Returns:
    
    the descriptive string
