FilterParser (OData V2 Library 1.12.0 API)

All Known Implementing Classes:

FilterParserImpl, OrderByParserImpl
```
public interface FilterParser
```
Interface which defines a method for parsing a $filter expression to allow different parser implementations
The current expression parser supports expressions as defined in the OData specification 2.0 with the following restrictions - the methods "cast", "isof" and "replace" are not supported The expression parser can be used with providing an Entity Data Model (EDM) an without providing it.
When a EDM is provided the expression parser will be as strict as possible. That means:
All properties used in the expression must be defined inside the EDM
The types of EDM properties will be checked against the lists of allowed type per method, binary- and unary operator

If no EDM is provided the expression parser performs a lax validation

The properties used in the expression are not looked up inside the EDM and the type of the expression node representing the property will be "null"
Expression node with EDM-types which are "null" are not considered during the parameter type validation, to the return type of the parent expression node will also become "null"
