org.mmbase.util.transformers
Class Base64

java.lang.Object
  org.mmbase.util.transformers.ByteArrayToCharTransformer
      org.mmbase.util.transformers.Base64

All Implemented Interfaces:

ByteToCharTransformer, ConfigurableTransformer, Serializable, Transformer

public class Base64

extends ByteArrayToCharTransformer

implements ByteToCharTransformer, ConfigurableTransformer

Uses the sun.misc classes to do BASE64 encoding and decoding. The sun.misc classes are not supported by Sun. Perhaps once we have to plug in another class.

Method Detail

configure

public void configure(int t)

Description copied from interface: ConfigurableTransformer

If a transformer can handle more then one destination format, it can be configured with this. There must be a default, since to can be null.

Specified by:

configure in interface ConfigurableTransformer

transformers

public Map transformers()

Used when registering this class as a possible Transformer

Specified by:

transformers in interface ConfigurableTransformer

Returns:

A Map with String Integer/Class pairs.

transform

public String transform(byte[] bytes)

Specified by:

transform in interface ByteToCharTransformer

Specified by:

transform in class ByteArrayToCharTransformer

transformBack

public byte[] transformBack(String r)

Specified by:

transformBack in interface ByteToCharTransformer

Overrides:

transformBack in class ByteArrayToCharTransformer

getEncoding

public String getEncoding()

Description copied from interface: ConfigurableTransformer

Returns the encoding that is currently active

Specified by:

getEncoding in interface ConfigurableTransformer

Returns:

An String representing the coding that is currently used.
