getAsString

@Nullable
public static String getAsString(@Nullable
                                            Object aParamName,
                                            @Nullable
                                            Object aValue,
                                            @Nullable
                                            String sDefault)

Get the string representation of the passed value, suitable for parameters.

Parameters:

aParamName - The name of the parameters. Has just informal character, for warnings. May be null.

aValue - The value to be converted to a String. May be null. Explicitly supported data types are: String, String[]. All other data types are returned as "toString()".

sDefault - The default value to be returned, if the passed value is null or an empty String array.

Returns:

The default value if the value is null or an empty String array, the value as string otherwise. If the value is a String[] than the first element is returned, and the other elements are discarded.
