public final class AddressString extends AbstractLazyEncodedByteArray implements FastSerializable
The API offered by this class is as if the type were specified in ASN.1 as follows.
AddressString ::= SEQUENCE { sMSAddress NULL OPTIONAL, nature Nature OPTIONAL, sMSNature sMSNature OPTIONAL, numberingPlan NumberingPlan, address DigitString }The class takes care of encoding the field values into a byte-array and decoding field values from a byte-array, the encoded representation being as tabulated below.
Data Encoding - based on comment in ASN.1 module MAP-CommonDataTypes in 3GPP TS 29.002 V10.0.0 (2010-09) p419 and 3GPP TS 23.040 V9.0.0 (2009-06) §9.1.2.5 p48 | ||||||||

Field sMSAddress, when present, indicates that an alphanumeric encoding of address is permitted: it determines whether nature or sMSNature is in the encoded form - either one or the other - it doesn't prevent values being set for the other, and both fields participate in the Map returned by getFieldsMap(), hence equals(), hashCode() and toString() are affected by both.
If sMSAddress is present and sMSNature is ALPHANUMERIC,
then address is encoded using the GSM7PACKED codec.
Otherwise, unless overridden by a particular StringCodec
,
each digit of the address field is encoded into a semi-octet,
and if there is an odd number of digits then the last semi-octet is assigned a filler.
The filler is 0xF and the encoding to semi-octets is as tabulated below.
