zoneStrings[i][0] - time zone ID
zoneStrings[i][1] - long name of zone in standard time
zoneStrings[i][2] - short name of zone in standard time
zoneStrings[i][3] - long name of zone in daylight savings time
zoneStrings[i][4] - short name of zone in daylight savings time

readObject

private void readObject(ObjectInputStream stream)
                 throws IOException,
                        ClassNotFoundException

First, read the default serializable fields from the stream. Then if serialVersionOnStream is less than 1, indicating that the stream was written by JDK 1.1, initialize useExponentialNotation to false, since it was not present in JDK 1.1. Finally, set serialVersionOnStream back to the maximum allowed value so that default serialization will work properly if this object is streamed out again.

If the minimum or maximum integer digit count is larger than DOUBLE_INTEGER_DIGITS or if the minimum or maximum fraction digit count is larger than DOUBLE_FRACTION_DIGITS, then the stream data is invalid and this method throws an InvalidObjectException.

Stream versions older than 2 will not have the affix pattern variables posPrefixPattern etc. As a result, they will be initialized to null, which means the affix strings will be taken as literal values. This is exactly what we want, since that corresponds to the pre-version-2 behavior.

maxOffset

int maxOffset

One less than the number of entries in offsets. Can also be thought of as the index of the highest-numbered element in offsets that is being used.

readObject

private void readObject(ObjectInputStream stream)
                 throws IOException,

First, read in the default serializable data. Then, if serialVersionOnStream is less than 1, indicating that the stream was written by JDK 1.1, set the int fields such as maximumIntegerDigits to be equal to the byte fields such as maxIntegerDigits, since the int fields were not present in JDK 1.1. Finally, set serialVersionOnStream back to the maximum allowed value so that default serialization will work properly if this object is streamed out again.

If minimumIntegerDigits is greater than maximumIntegerDigits or minimumFractionDigits is greater than maximumFractionDigits, then the stream data is invalid and this method throws an InvalidObjectException. In addition, if any of these values is negative, then this method throws an InvalidObjectException.

Reconstitute this object from a stream (i.e., deserialize it).

writeObject

private void writeObject(ObjectOutputStream stream)
                  throws IOException

Save the state of this object to a stream (i.e., serialize it). Ideally, Calendar would only write out its state data and the current time, and not write any field data out, such as fields[], isTimeSet, areFieldsSet, and isSet[]. nextStamp also should not be part of the persistent state. Unfortunately, this didn't happen before JDK 1.1 shipped. To be compatible with JDK 1.1, we will always have to write out the field values and state flags. However, nextStamp can be removed from the serialization stream; this will probably happen in the near future.

Serialized Fields

fields

int[] fields

The field values for the currently set time for this calendar. This is an array of FIELD_COUNT integers, with index values ERA through DST_OFFSET.

isSet

boolean[] isSet

The flags which tell if a specified time field for the calendar is set. A new object has no fields set. After the first call to a method which generates the fields, they all remain set after that. This is an array of FIELD_COUNT booleans, with index values ERA through DST_OFFSET.

See Also:: Calendar.time

areFieldsSet

boolean areFieldsSet

True if fields[] are in sync with the currently set time. If false, then the next attempt to get the value of a field will force a recomputation of all fields from the current value of time.

lenient

boolean lenient

True if this calendar allows out-of-range field values during computation of time from fields[].

See Also:: Calendar.setLenient(boolean)

zone

TimeZone zone

The TimeZone used by this calendar. Calendar uses the time zone data to translate between locale and GMT time.

int minimalDaysInFirstWeek

The number of days required for the first week in a month or year, with possible values from 1 to 7. This is a locale-dependent value.

nextStamp

int nextStamp

The next available value for stamp[], an internal array. This actually should not be written out to the stream, and will probably be removed from the stream in the near future. In the meantime, a value of MINIMUM_USER_STAMP should be used.

serialVersionOnStream

int serialVersionOnStream

The version of the serialized data on the stream. Possible values:

0 or not present on stream: JDK 1.1.5 or earlier.

Serialized Fields

startMonth

int startMonth

The month in which daylight savings time starts. This value must be between Calendar.JANUARY and Calendar.DECEMBER inclusive. This value must not equal endMonth.

If useDaylight is false, this value is ignored.

startDay

startMode == DOW_IN_MONTH

startDay indicates the day of the month of startMonth on which daylight savings time starts, from 1 to 28, 30, or 31, depending on the startMonth.

startMode != DOW_IN_MONTH

startDay indicates which startDayOfWeek in th month startMonth daylight savings time starts on. For example, a value of +1 and a startDayOfWeek of Calendar.SUNDAY indicates the first Sunday of startMonth. Likewise, +2 would indicate the second Sunday, and -1 the last Sunday. A value of 0 is illegal.

If useDaylight is false, this value is ignored.

startDayOfWeek

Since:: JDK1.1.4

dstSavings

int dstSavings

A positive value indicating the amount of time saved during DST in milliseconds. Typically one hour (3600000); sometimes 30 minutes (1800000).

If useDaylight is false, this value is ignored.

Since:: JDK1.1.4

serialVersionOnStream

int serialVersionOnStream

The version of the serialized data on the stream. Possible values:

0 or not present on stream: JDK 1.1.3 or earlier.
1: JDK 1.1.4 or later. Includes three new fields: startMode, endMode, and dstSavings.
2: JDK 1.3 or later. Includes two new fields: startTimeMode and endTimeMode.

When streaming out this class, the most recent format and the highest allowable serialVersionOnStream is written.

Since:: JDK1.1.4

Class java.util.Stack implements Serializable

Class java.util.TimeZone implements Serializable

Serialized Fields

ID

String ID

The string identifier of this TimeZone. This is a programmatic identifier used internally to look up TimeZone objects from the system table and also to map them to their localized display names. ID values are unique in the system table but may not be for dynamically created zones.

Class java.util.TooManyListenersException implements Serializable

Class java.util.TreeMap implements Serializable

Serialization Methods

readObject

private void readObject(ObjectInputStream s)
                 throws IOException,
                        ClassNotFoundException

Reconstitute the TreeMap instance from a stream (i.e., deserialize it).

writeObject

private void writeObject(ObjectOutputStream s)
                  throws IOException

Save the state of the TreeMap instance to a stream (i.e., serialize it).

Serial Data:: The size of the TreeMap (the number of key-value mappings) is emitted (int), followed by the key (Object) and value (Object) for each key-value mapping represented by the TreeMap. The key-value mappings are emitted in key-order (as determined by the TreeMap's Comparator, or by the keys' natural ordering if the TreeMap has no Comparator).; IOException

Serialized Fields

comparator

Comparator comparator

The Comparator used to maintain order in this TreeMap, or null if this TreeMap uses its elements natural ordering.

Class java.util.TreeSet implements Serializable

Serialization Methods

readObject

private void readObject(ObjectInputStream s)
                 throws IOException,
                        ClassNotFoundException

Reconstitute the TreeSet instance from a stream (that is, deserialize it).

writeObject

private void writeObject(ObjectOutputStream s)
                  throws IOException

Save the state of the TreeSet instance to a stream (that is, serialize it).

Serial Data:: Emits the comparator used to order this set, or null if it obeys its elements' natural ordering (Object), followed by the size of the set (the number of elements it contains) (int), followed by all of its elements (each an Object) in order (as determined by the set's Comparator, or by the elements' natural ordering if the set has no Comparator).; IOException

Class java.util.Vector implements Serializable

Serialized Fields

elementData

Object[] elementData

The array buffer into which the components of the vector are stored. The capacity of the vector is the length of this array buffer, and is at least large enough to contain all the vector's elements.

Any array elements following the last element in the Vector are null.

elementCount

int elementCount

The number of valid components in this Vector object. Components elementData[0] through elementData[elementCount-1] are the actual items.

capacityIncrement

int capacityIncrement

The amount by which the capacity of the vector is automatically incremented when its size becomes greater than its capacity. If the capacity increment is less than or equal to zero, the capacity of the vector is doubled each time it needs to grow.
