FilterCapabilities (Geotools modules 29-SNAPSHOT API)

Object
- FilterCapabilities

```
public class FilterCapabilities
extends Object
```
Represents the Filter capabilities that are supported by a SQLEncoder
Each SQLEncoder class should have one static FilterCapabilities, representing the filter encoding operations that it can successfully perform.
This class is used as one big mask to detect filters that cannot be performed

Author:

Chris Holmes, TOPP TODO: check if possible to deprecate @ deprecated use FilterCapabilities.

- Method Detail
  - addType
```
public void addType(long type)
```
    Adds a new support type to capabilities.
    
    Parameters:
    
    type - The one of the masks enumerated in this class
  - addType
```
public void addType(Class type)
```
    Adds a new support type to capabilities. For 2.2 only function expression support is added this way. As of geotools 2.3 this will be the supported way of adding to Filtercapabilities.
    
    Parameters:
    
    type - the Class that indicates the new support.
  - addType
```
public void addType(Class type,
                    boolean addFunctionType)
```
    Adds a new support type to capabilities. For 2.2 only function expression support is added this way. As of geotools 2.3 this will be the supported way of adding to Filtercapabilities.
    
    Parameters:
    
    type - the Class that indicates the new support.
  - addAll
```
public void addAll(FilterCapabilities capabilities)
```
    Add all the capabilities in the provided FilterCapabilities to this capabilities.
    
    Parameters:
    
    capabilities - capabilities to add.
  - convertFilterTypeToMask
```
public FilterCapabilities convertFilterTypeToMask(short type)
```
    Returns the mask that is equivalent to the FilterType constant.
    
    Parameters:
    
    type - a constant from FilterType
    
    Returns:
    
    the mask that is equivalent to the FilterType constant.
  - supports
```
public boolean supports(Filter filter)
```
    Determines if the filter passed in is supported.
    
    Parameters:
    
    filter - The Filter to be tested.
    
    Returns:
    
    true if supported, false otherwise.
  - fullySupports
```
public boolean fullySupports(Filter filter)
```
    Determines if the filter and all its sub filters are supported. Is most important for logic filters, as they are the only ones with subFilters. Null filters should not be used here, if nothing should be filtered than Filter.INCLUDE can be used. Embedded nulls can be a particular source of problems, buried in logic filters.
    
    Parameters:
    
    filter - the filter to be tested.
    
    Returns:
    
    true if all sub filters are supported, false otherwise.
    
    Throws:
    
    IllegalArgumentException - If a null filter is passed in. As this function is recursive a null in a logic filter will also cause an error.

```
public long getScalarOps()
```
  - getSpatialOps
```
public long getSpatialOps()
```
  - findOperation
```
public static FilterCapabilities findOperation(String name)
```
    Translates a String into an object that represents the operation
    
    Parameters:
    
    name - String, operation name
    
    Returns:
    
    one of the FilterCapabilities constants
  - findFunction
```
public static FilterCapabilities findFunction(String name)
```
    Translates a String into an object that represents function expression
    
    Parameters:
    
    name - String, expression name
    
    Returns:
    
    one of the FilterCapabilities constants
