## org.codehaus.groovy.runtime
[Java] Class EncodingGroovyMethods

    java.lang.Object
      org.codehaus.groovy.runtime.EncodingGroovyMethods

    public class EncodingGroovyMethods
    extends java.lang.Object

This class defines all the encoding/decoding groovy methods which enhance the normal JDK classes when inside the Groovy environment. Static methods are used with the first parameter the destination class.

Method Summary
`static byte[]` | `decodeBase64(java.lang.String value)` Decode the String from Base64 into a byte array.
`static byte[]` | `decodeHex(java.lang.String value)` Decodes a hex string to a byte array.
`static Writable` | `encodeBase64(java.lang.Byte[] data, boolean chunked)` Produce a Writable object which writes the Base64 encoding of the byte array.
`static Writable` | `encodeBase64(java.lang.Byte[] data)` Produce a Writable object which writes the Base64 encoding of the byte array.
`static Writable` | `encodeBase64(byte[] data, boolean chunked)` Produce a Writable object which writes the Base64 encoding of the byte array.
`static Writable` | `encodeBase64(byte[] data)` Produce a Writable object which writes the Base64 encoding of the byte array.
`static Writable` | `encodeHex(java.lang.Byte[] data)` Produces a Writable that writes the hex encoding of the Byte[].
`static Writable` | `encodeHex(byte[] data)`

Method Detail

### decodeBase64

    public static byte[] decodeBase64(java.lang.String value)

  Decode the String from Base64 into a byte array.
  Parameters:
    `value` - the string to be decoded
  Returns:
    the decoded bytes as an array
  Since:
    1.0

### decodeHex

    public static byte[] decodeHex(java.lang.String value)

  Decodes a hex string to a byte array. The hex string can contain either upper case or lower case letters.
  throws:
    NumberFormatException If the string contains an odd number of characters or if the characters are not valid hexadecimal values.
  Parameters:
    `value` - string to be decoded
  Returns:
    decoded byte array

### encodeBase64

    public static Writable encodeBase64(java.lang.Byte[] data, boolean chunked)

  Produce a Writable object which writes the Base64 encoding of the byte array. Calling toString() on the result returns the encoding as a String. For more information on Base64 encoding and chunking see `RFC 4648`.
  Parameters:
    `data` - Byte array to be encoded
    `chunked` - whether or not the Base64 encoded data should be MIME chunked
  Returns:
    object which will write the Base64 encoding of the byte array
  Since:
    1.5.1

### encodeBase64

    public static Writable encodeBase64(java.lang.Byte[] data)

  Produce a Writable object which writes the Base64 encoding of the byte array. Calling toString() on the result returns the encoding as a String. For more information on Base64 encoding and chunking see `RFC 4648`.
  Parameters:
    `data` - Byte array to be encoded
  Returns:
    object which will write the Base64 encoding of the byte array
  Since:
    1.0

### encodeBase64

    public static Writable encodeBase64(byte[] data, boolean chunked)

  Produce a Writable object which writes the Base64 encoding of the byte array. Calling toString() on the result returns the encoding as a String. For more information on Base64 encoding and chunking see `RFC 4648`.
  Parameters:
    `data` - byte array to be encoded
    `chunked` - whether or not the Base64 encoded data should be MIME chunked
  Returns:
    object which will write the Base64 encoding of the byte array
  Since:
    1.5.7

### encodeBase64

    public static Writable encodeBase64(byte[] data)

  Produce a Writable object which writes the Base64 encoding of the byte array. Calling toString() on the result returns the encoding as a String. For more information on Base64 encoding and chunking see `RFC 4648`.
  Parameters:
    `data` - byte array to be encoded
  Returns:
    object which will write the Base64 encoding of the byte array
  Since:
    1.0

### encodeHex

    public static Writable encodeHex(java.lang.Byte[] data)

  Produces a Writable that writes the hex encoding of the Byte[]. Calling toString() on this Writable returns the hex encoding as a String. The hex encoding includes two characters for each byte and all letters are lower case.
  Parameters:
    `data` - byte array to be encoded
  Returns:
    object which will write the hex encoding of the byte array
  See Also:
    java.lang.Integer#toHexString(int)

### encodeHex

    public static Writable encodeHex(byte[] data)
