HardcodedFilter (spring-ldap-core 2.4.1 API)

java.lang.Object
- org.springframework.ldap.filter.AbstractFilter
- - org.springframework.ldap.filter.HardcodedFilter

All Implemented Interfaces:

Filter
```
public class HardcodedFilter
extends AbstractFilter
```
Allows hard coded parts to be included in a search filter. Particularly useful if some filters are specified in configuration files and these should be combined with other ones.
```
 Filter filter = new HardcodedFilter("(&(objectClass=user)(!(objectClass=computer)))");
 System.out.println(filter.toString());
 
```
would result in: (&(objectClass=user)(!(objectClass=computer)))
Note 1: If the definition is in XML you will need to properly encode any special characters so that they are valid in an XML file, e.g. "&" needs to be encoded as "&", e.g.
```
 <bean class="MyClass">
   <property name="filter" value="(&amp;(objectClass=user)(!(objectClass=computer)))" />
 </bean>
 
```
Note 2: There will be no validation to ensure that the supplied filter is valid. Using this implementation to build filters from user input is strongly discouraged.
