init
public void init(java.util.Map<java.lang.String,java.lang.String> settings) throws java.lang.Exception
The no-transformer does not take any parameters and therefore must not be initialized. This method does nothing.- Specified by:
init

- Parameters:
settings
- Implementation-specific setting map- Throws:
java.lang.Exception
- If the given settings are invalid or insufficient for instantiation
-
createOutputStream
public java.io.OutputStream createOutputStream(java.io.OutputStream out) throws java.io.IOException
Description copied from class:Transformer
Create a stream-transformingOutputStream
. Depending on the implementation, the bytes written to the output stream might be encrypted, compressed, etc.- Specified by:
createOutputStream
in classTransformer
- Parameters:
out
- Original output stream which is transformed by this transformer- Returns:
- Returns a transformed output stream
- Throws:
java.io.IOException
- If an exception occurs when instantiating or writing to the stream
-
createInputStream
public java.io.InputStream createInputStream(java.io.InputStream in) throws java.io.IOException
Description copied from class:Transformer
Creates a strea-transformingInputStream
. Depending on the implementation, the bytes read from the input stream are uncompressed, decrypted, etc.- Specified by:
createInputStream
in classTransformer
- Parameters:
in
- Original input stream which is transformed by this transformer- Returns:
- Returns a transformed input stream
- Throws:
java.io.IOException
- If an exception occurs when instantiating or reading from the stream
-
toString
public java.lang.String toString()
Description copied from class:Transformer
An implementation of a transformer must override this method to identify the type of transformer and/or its settings.- Specified by:
toString
in classTransformer
