field

public static String field(String name,
                           String value)

According to specifications, the SDK user agent consists of metadata fields separated by RWS characters - in this implementation, space. Each field is represented by the name of the field, as specified and the contents of the field, separated with a '/' (SLASH). Contents can be a single token, a specified value or a uaPair.

uaPair

public static String uaPair(String name,
                            String value)

According to specifications, an SDK user agent pair is a name, value pair concatenated with a '#' (HASH).

uaPairOrNull

public static String uaPairOrNull(String name,
                                  String value)

According to specifications, an SDK user agent pair is a name, value pair concatenated with a '#' (HASH).

appendFieldAndSpace

public static void appendFieldAndSpace(StringBuilder builder,
                                       String name,
                                       String value)

Add a metadata field to the string builder, followed by space. If 'value' can be empty, use appendNonEmptyField(StringBuilder, String, String) instead.

appendSpaceAndField

public static void appendSpaceAndField(StringBuilder builder,
                                       String name,
                                       String value)

Add a metadata field to the string builder, preceded by space. If 'value' can be empty, use appendNonEmptyField(StringBuilder, String, String) instead.
