QueryParameter (XWiki Platform - Query - Manager 15.4 API)

```
public interface QueryParameter
```
Represents a parameter of a Query. This is providing an API to represent a query parameter as made of several parts:
- literal parts: those are constructed by calling literal(String) and their characters will be escaped when the Query will executed (i.e. %, _ and ! characters will get escaped)
- special SQL characters: constructed by calling anyChars() and anychar() which correspond respectively to the % and _ SQL characters.
Example:
```
 #set(xwql = "WHERE doc.fullName LIKE :space AND doc.fullName <> :fullName")
 #set ($query = $services.query.xwql(xwql))
 #set ($query = $query.bindValue('space').literal($doc.space).literal('.').anyChars().query())
 
```
