Class SingleByteCharsetConverter

    java.lang.Object
      com.mysql.jdbc.SingleByteCharsetConverter

    public class SingleByteCharsetConverter

extends java.lang.Object

Converter for char[]->byte[] and byte[]->char[] for single-byte character sets. Much faster (5-6x) than the built-in solution that ships with the JVM, even with JDK-1.4.x and NewIo.

Method Summary
`static SingleByteCharsetConverter` `getInstance(java.lang.String encodingName, Connection conn)` Get a converter for the given encoding name
`static SingleByteCharsetConverter` `initCharset(java.lang.String javaEncodingName)` Initialize the shared instance of a converter for the given character encoding.
`byte[]` `toBytes(char[] c)`
`byte[]` `toBytes(char[] chars, int offset, int length)`
`byte[]` `toBytes(java.lang.String s)` Convert the given string to an array of bytes.
`byte[]` `toBytes(java.lang.String s, int offset, int length)` Convert the given string to an array of bytes.
`byte[]` `toBytesWrapped(char[] c, char beginWrap, char endWrap)`
`byte[]` `toBytesWrapped(java.lang.String s, char beginWrap, char endWrap)`
`java.lang.String` `toString(byte[] buffer)` Convert the byte buffer to a string using this instance's character encoding.
`java.lang.String` `toString(byte[] buffer, int startPos, int length)` Convert the byte buffer from startPos to a length of length to a string using this instance's character encoding.
`static java.lang.String` `toStringDefaultEncoding(byte[] buffer, int startPos, int length)` Convert the byte buffer from startPos to a length of length to a string using the default platform encoding.
