Class Base64Handler

java.lang.Object
  org.openliberty.arisid.util.Base64Handler

public class Base64Handler
extends java.lang.Object

Base64 Handler for encode/decode. This handler supports the ability to use different Base64 encode/decode implementations. To switch Base64 implementation, a wrapper module must be written that implements the IBase64 interface. To switch Base64 provider, set the system property "org.openliberty.arisid.util.Base64.class" BASE64_CLASS to the name of the class implementing IBase64. The Base64 implementation will be instantiated on the first call to Base64.getInstance()

Field Summary

Method Summary

byte[]	decode(java.lang.String inStr) Decodes Base64 encoded data into byte array
java.lang.String	encode(byte[] inBytes) Encodes byte array into Base64 string
static Base64Handler	getInstance() Obtains a handle to the Base64 encode/decode class.

Method Detail

getInstance

public static Base64Handler getInstance()

Obtains a handle to the Base64 encode/decode class. The first time this method is called, the declared Base64 encode/deocde implementation class will be instantiated. The default is: "org.openliberty.arisid.util.Base64" To override the default, set the system property "org.openliberty.arisid.base64.class" to the name of the class implementing IBase64 interface.

Returns:

a handler to the Base64Handler system

Throws:

java.lang.ClassCastException - If the specified class does not implement IBase64

java.lang.ClassNotFoundException - If the specified class cannot be loaded.

encode

public java.lang.String encode(byte[] inBytes)

Encodes byte array into Base64 string

Parameters:

inBytes - Array containing binary data

Returns:

Base64 encoded string

decode

public byte[] decode(java.lang.String inStr)

Decodes Base64 encoded data into byte array

Parameters:

inStr - Base64 encoded string

Returns:

byte array containing decoded data
