Class oracle.sql.CharacterSet 

java.lang.Object
   |
   +----oracle.sql.CharacterSet
public abstract class CharacterSet
extends Object
Encapsulates methods and attributes of the character sets defined by Oracle. Mostly this means conversions between representations. A better name for this class would probably be CharacterRepresentation, but "character set" is how all the Oracle documentation refers to these things.

There are no public constructors. To create a CharacterSet use oracle.sql.CharacterSetFactory. There is no notion of "unsupported" character set. CharacterSet's can be created with any oracleId. However, there is a notion of unsupported conversions And the current implementation is limited to the small number of character sets for which constants are defined in the class

When there are two variants of an operation (e.g. convert vs. convertUnshared) the plain version is the fast (but possibly unsafe) one.

The descriptions of methods in this class use the phrase "bytes in oracleId representation". What this means is that the bytes can be interpreted as a sequence of characters in the character set defined by oracleId. Both what characters are available and how they are represented as sequences of bytes is determined by oracleId.

Methods

o make 
 public static CharacterSet make(int oracleId)
Factory. A factory is used rather than a constructor because CharacterSet is abstract.

Parameters:
oracleId - the number of the Oracle character set. A list of official Oracle character sets is maintained by ...
Returns:
CharacterSet for oracleId.
o toString 
 public String toString()
This should be the official name of the character set. I don't know them so I just return a string containing the oracleId -- jschwarz

Returns:
the name of the character set
Overrides:
toString in class Object
o isLossyFrom 
 public abstract boolean isLossyFrom(CharacterSet from)
A conversion looses information if the mapping is not invertible. (A mathematicial would say that the map of characters in from to this is not injective.)

Parameters:
from - a CharacterSet being tested for compatibility with this CharacterSet.
Returns:
true if characters in the from character set can be mapped uniquely to characters in oracleId representation.
o isConvertibleFrom 
 public abstract boolean isConvertibleFrom(CharacterSet source)
Are conversions supported.

Parameters:
source - a CharacterSet to inquire about
Returns:
true if conversion from source to oracleId is supported. If it isn't supported attempts to convert will always throw exceptions.
o getOracleId 
 public int getOracleId()
The integer that identifies the character set.

o getRatioTo 
 public int getRatioTo(CharacterSet to)
I have no idea what this is supposed to return -- jschwarz.

o equals 
 public boolean equals(Object rhs)
Two CharacterSet's are equal when their oracleId's are equal

Overrides:
equals in class Object
o hashCode 
 public int hashCode()
Implements a hash based on oracleId

Overrides:
hashCode in class Object
o toStringWithReplacement 
 public abstract String toStringWithReplacement(byte bytes[],
                                                int offset,
                                                int count)
Convert bytes in oracleId representation to a String. If a character has no Unicode representation the effect is unspecified. The conversion might omit it, or replace it with a special character. The preferred result is replacement by a single character, but it is not guaranteed. If the conversion isn't supported at all, the result may be a fixed string.

Parameters:
bytes - a array containing characters represented in this character set.
offset - the index of the first byte or the charcters
count - the number of bytes to be converted.
Returns:
the String resulting from converting to UCS-2.
o toString 
 public String toString(byte bytes[],
                        int offset,
                        int count) throws SQLException
Convert bytes in oracleId representation to a String. The difference between toStringInvertible and plain toString is that toStringInvertible will throw an exception when toString would make some replacement.

Parameters:
bytes - a array containing characters represented in this character set.
offset - the index of the first byte or the charcters
count - the number of bytes to be converted.
Returns:
the String resulting from converting to UCS-2.
Throws: SQLException
when conversion is not supported.
Throws: SQLException
when some character contained in bytes has no Unicode equivalent.
o convert 
 public abstract byte[] convert(String s) throws SQLException
Convert a String to bytes in oracleId representation.

Returns:
an array containing the sequence of bytes in oracleId representation that represent the sequence of Unicode characters in String.
Throws: SQLException
when the oracleId does not support conversion from Unicode.
Throws: SQLException
when s contains a character that cannot be converted.
o convertWithReplacement 
 public abstract byte[] convertWithReplacement(String s)
Convert a String to bytes in oracleId representation. A String is always produced even when the conversion isn't supported or s contains characters that do not have a representation in oracleId. The usual conversion is to replace characters that don't have a representation with some fixed character, but that is not guranteed.

Returns:
an array containing the sequence of bytes in oracleId representation that represent the sequence of Unicode characters in String.
o convert 
 public abstract byte[] convert(CharacterSet from,
                                byte source[],
                                int offset,
                                int count) throws SQLException
Converts bytes in some representation to oracleId representation. Note that the input is not guaranteed to be different from the output. If a copy is always wanted then use convertUnshared.

Parameters:
from - the character set of the input bytes
source - an array of bytes containing the bytes to be converted
offset - the index of the first byte to be converted
count - the number of bytes to be converted
Throws: SQLException
if the conversion is not supported
Throws: SQLException
if some character cannot be converted. This exception is not guaranteed to be thrown. For some conversions a replacement character may be used instead.
o convertUnshared 
 public byte[] convertUnshared(CharacterSet from,
                               byte source[],
                               int offset,
                               int count) throws SQLException
Converts bytes in some representation to oracleId representation. This is identical to convert except that it always returns a copy of it's input.

Parameters:
from - the character set of the input bytes
source - an array of bytes containing the bytes to be converted
offset - the index of the first byte to be converted
count - the number of bytes to be converted
Returns:
an array containing a representation as an oracleId of characters in the source.
Throws: SQLException
if the conversion is not supported.
Throws: SQLException
if some character could not be converted. This exception is not guaranteed to be thrown. For some conversions a replacement character may be used instead.
