TupleTypes

public TupleTypes()

Method Detail

getTypeName

public static java.lang.String getTypeName(int type)

isNumeric

public static boolean isNumeric(int tupleType)

Returns whether the given tuple type is numeric. The following tuple types are numeric:

• SHORT
• INT
• LONG
• FLOAT
• DOUBLE
• BIGDECIMAL

All of these these types will correspond to data values that can be case to java.lang.Number if they are not uk.org.ogsadai.tuple.Null.VALUE.

Parameters:

tupleType - the tuple type, one of the constants defined in TupleTypes

Returns:

true if the type type is number, false otherwise.
