Method Detail

acceptInt

public void acceptInt(int value)

Description copied from class: AbstractIntAcceptor

Accept an int, after closed check and test for end of data. Implementing classes must supply an implementation of this method.

Specified by:

acceptInt in class AbstractIntAcceptor<R>

Parameters:

value - the input value

isStageComplete

public boolean isStageComplete()

Description copied from interface: BasePipeline

Return true if all sequences in the input to this stage of the pipeline are complete, that is, the input is not in the middle of a sequence requiring more data. This should be overridden by pipeline stages that process complex sequences of input.

Returns:

true if the input is in the "complete" state

convert

public static byte[] convert(byte[] input,
                             ErrorStrategy errorStrategy)

Convert a byte array using the Base64Decoder converter.

Parameters:

input - the input as a byte array

errorStrategy - the ErrorStrategy

Returns:

the converted data as a String

convert

public static byte[] convert(byte[] input)

Convert a byte array using the Base64Decoder converter.

Parameters:

input - the input as a byte array

Returns:

the converted data as a String

convert

public static String convert(String input,
                             ErrorStrategy errorStrategy)

Convert a String using the Base64Decoder converter.

Parameters:

input - the input as a String

errorStrategy - the ErrorStrategy

Returns:

the converted data as a String

convert

public static String convert(String input)

Convert a String using the Base64Decoder converter.

Parameters:

input - the input as a String

Returns:

the converted data as a String

convert

public static List<Integer> convert(List<Integer> input,
                                    ErrorStrategy errorStrategy)

Convert a List<Integer> (Unicode code points) using the Base64Decoder converter.

Parameters:

input - the input as a List<Integer>

errorStrategy - the ErrorStrategy

Returns:

the converted data as a String

convert

public static List<Integer> convert(List<Integer> input)

Convert a List<Integer> (Unicode code points) using the Base64Decoder converter.

Parameters:

input - the input as a List<Integer>

Returns:

the converted data as a String
