ServerSideFunction (cdm-lite 7.0.0-SNAPSHOT API)

All Known Subinterfaces:

BoolFunction, BTFunction
```
public interface ServerSideFunction
```
Represents common interface of all server-side functions (SSF). Implementing this interface is not sufficient to create a working SSF. SSF's must implement (at least) one of the subinterfaces BoolFunction and BTFunction.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description

`String`	`getName()`	Returns the name of the server-side function, as it will appear in constraint expressions.

- Method Detail
  - getName
```
String getName()
```
    Returns the name of the server-side function, as it will appear in constraint expressions. This must be a valid OPeNDAP identifier. All functions must have distinct names.
  - checkArgs
```
void checkArgs(List args)
        throws InvalidParameterException
```
    Checks that the arguments given are acceptable arguments for this function. This method should only use those attributes of a SubClause which do not change over its lifetime - whether it is constant, what class of SubClause it is, what class of BaseType it returns, etc. Thus, the method should not look at the actual value of an argument unless the argument is flagged as constant.
    
    Parameters:
    
    args - A list of SubClauses that the caller is considering passing to the evaluate() method of the function.
    
    Throws:
    
    InvalidParameterException - Thrown if the function will not evaluate successfully using these arguments.
