public final class Treatment
extends AbstractLazyEncodedByteArray
implements FastSerializable

Class Treatment represents whether a particular type of call is to be accepted or rejected.

The API offered by this class is as if the type were specified in ASN.1 as follows.

 Treatment ::= SEQUENCE {
     treatmentValue TreatmentValue
 }

The class takes care of encoding the field value into a byte-array and decoding the field value from a byte-array, the encoded representation being as tabulated below.

Constructor Detail

Treatment

public Treatment()

Constructs a new Treatment object with no fields set.

Treatment

public Treatment(byte[] data)

Constructs a new Treatment object from network-encoded data. The data is not decoded and might not be decodable.

Parameters:

data - network-encoded data

Throws:

NullPointerException - if data is null

Treatment

public Treatment(byte[] data,
         int start,
         int len)

Constructs a new Treatment object from part of network-encoded data. The part starts at index start and is len bytes long. The data is not decoded and might not be decodable.

Parameters:

data - network-encoded data

start - starting offset of network-encoded data in byte array

len - default length if not predictable

Throws:

NullPointerException - if data is null

IllegalArgumentException - if len is negative

Treatment

public Treatment(Treatment.TreatmentValue treatmentValue)

Constructs a new Treatment object from given values for all fields.

Parameters:

treatmentValue - the treatment value

Treatment

public Treatment(DataInput in)
          throws IOException

Constructs a new Treatment object from data deserialized from a stream that was written by toStream(DataOutput).

Parameters:

in - the stream to read from

Throws:

EOFException - if reading is pre-empted by end-of-file

IOException - if the data cannot be read

Method Detail

toStream

public void toStream(DataOutput out)
              throws IOException

Serializes this object to a stream in a form suitable for reading by Treatment(DataInput).

Specified by:

toStream in interface FastSerializable

Parameters:

out - the stream to write to

Throws:

IOException - if an I/O error occurs

hasTreatmentValue

public boolean hasTreatmentValue()
                          throws DecodeException

Tests whether the field TreatmentValue has a value.

Returns:

whether the field has a value

Throws:

DecodeException - if encoded state cannot be decoded

checkFieldsSet

public void checkFieldsSet()
                    throws EncodeException

Checks that all mandatory fields are present. Should be called immediately before all calls to encode().

Specified by:

checkFieldsSet in class AbstractLazyEncodedDataObject<byte[]>

Throws:

EncodeException - if any mandatory field is not present

getTreatmentValue

public Treatment.TreatmentValue getTreatmentValue()
                                           throws DecodeException

Gets the value of the treatment value.

Returns:

TreatmentValue representation of the treatment value

Throws:

DecodeException - if encoded state cannot be decoded

setTreatmentValue

public Treatment setTreatmentValue(Treatment.TreatmentValue value)
                            throws IllegalStateException

Sets the value of the treatment value.

Parameters:

value - TreatmentValue representation of the treatment value

Returns:

this

Throws:

IllegalStateException

copyOf

public static Treatment copyOf(Treatment from)

Creates a new object of this type, cloning the values of common fields from the given object of any subclass of the same base type.

Parameters:

from - the object from which to copy

Returns:

Treatment

clone

public Treatment clone()

Constructs a copy of this object and everything reachable from it.

Specified by:

clone in interface DataObject

Specified by:

clone in class AbstractDataObject

Returns:

copy of object

getFieldAccessors

public static FieldAccessor[] getFieldAccessors()

Gets a new array of the accessors for fields of this type.

Returns:

FieldAccessor[]

getFieldsMap

public Map<String,Object> getFieldsMap(boolean withAbsents)

Gets a Map from field-name to field-value for the fields of a sequence. For a field of primitive type, the field-value is boxed. For an absent optional field, the field-value is AbstractFieldsObject.FIELD_ABSENT. For an uninitialised mandatory field, the field-value is AbstractFieldsObject.FIELD_UNINITIALISED. For a field of String type, the encoded form is used if the String cannot be decoded. For a type that represents an OCTET STRING that cannot be decoded, a map from "encodedValue" to the byte array value is returned.

Specified by:

getFieldsMap in class AbstractFieldsObject

Parameters:

withAbsents - whether to put absent optional fields into Map

Returns:

Map from field-name to field-value

encodedIsInvalid

protected boolean encodedIsInvalid()

Determines whether the encoded form is invalid.

Returns:

boolean

getEncodedForm

public byte[] getEncodedForm()
                      throws EncodeException

Gets the encoded form.

Returns:

encoded form

Throws:

EncodeException - if encoding fails

getContainedLength

public static int getContainedLength(byte[] data,
                     int start,
                     int len)

Determines the length of the encoded value that commences at offset start in the given data. The value is not fully decoded and might not be decodable. Values of this type are of a fixed length, so that length is returned if the data is long enough, otherwise 0 is returned.

Parameters:

data - network-encoded data

start - index into data where value commences

len - length in data to be considered

Returns:

1, or 0 if encoded value is not long enough

encode

protected void encode()

Computes the encoded form from the decoded form.

Specified by:

encode in class AbstractLazyEncodedDataObject<byte[]>

decode

protected void decode()
               throws DecodeException

Computes the decoded form from the encoded form.

Specified by:

decode in class AbstractLazyEncodedDataObject<byte[]>

Throws:

DecodeException - if not 1 octet to be decoded
