Method Detail

getName

public java.lang.String getName()

Description copied from interface: ServerSideFunction

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.

Specified by:

getName in interface ServerSideFunction

checkArgs

public void checkArgs(java.util.List args)

Description copied from interface: ServerSideFunction

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.

Specified by:

checkArgs in interface ServerSideFunction

Parameters:

args - A list of SubClauses that the caller is considering passing to the evaluate() method of the function.

evaluate

public boolean evaluate(java.util.List args)

Description copied from interface: BoolFunction

Evaluates the function using the argument list given.
