Base16Codec

public Base16Codec()

Creates a Base16 codec used for decoding and encoding.

Method Details

getMaximumEncodedLength

@Nonnegative
public int getMaximumEncodedLength(@Nonnegative
 int nDecodedLen)

Description copied from interface: IByteArrayEncoder

Get the maximum encoded length based on the provided decoded length. This is purely for performance reasons. The name of the method would be better called "getMaximumEncodedLength".

Specified by:

getMaximumEncodedLength in interface IByteArrayEncoder

Specified by:

getMaximumEncodedLength in interface IByteArrayStreamEncoder

Parameters:

nDecodedLen - The decoded length. Always ≥ 0.

Returns:

The maximum encoded length. Always ≥ 0.

encode

public void encode(@Nonnull @WillNotClose
 InputStream aDecodedIS,
 @Nonnull @WillNotClose
 OutputStream aOS)

encode

public void encode(@Nullable
 byte[] aDecodedBuffer,
 @Nonnegative
 int nOfs,
 @Nonnegative
 int nLen,
 @Nonnull @WillNotClose
 OutputStream aOS)

Description copied from interface: IByteArrayStreamEncoder

Encode (part of) a byte array to an OutputStream.

Specified by:

encode in interface IByteArrayStreamEncoder

Parameters:

aDecodedBuffer - The byte array to be encoded. May be null.

nOfs - Offset into the byte array to start from.

nLen - Number of bytes starting from offset to consider.

aOS - The output stream to write to. May not be null and is NOT closed afterwards!

getMaximumDecodedLength

@Nonnegative
public int getMaximumDecodedLength(@Nonnegative
 int nEncodedLen)

Description copied from interface: IByteArrayDecoder

Get the maximum decoded length based on the provided encoded length. This is purely for performance reasons.

Specified by:

getMaximumDecodedLength in interface IByteArrayDecoder

Parameters:

nEncodedLen - The encoded length. Always ≥ 0.

Returns:

The maximum decoded length. Always ≥ 0.

decode

public void decode(@Nonnull @WillNotClose
 InputStream aEncodedIS,
 @Nonnull @WillNotClose
 OutputStream aOS)

decode

public void decode(@Nullable
 byte[] aEncodedBuffer,
 @Nonnegative
 int nOfs,
 @Nonnegative
 int nLen,
 @Nonnull @WillNotClose
 OutputStream aOS)

Description copied from interface: IByteArrayStreamDecoder

Decode (part of) a byte array.

Specified by:

decode in interface IByteArrayStreamDecoder

Parameters:

aEncodedBuffer - The byte array to be decoded. May be null.

nOfs - Offset into the byte array to start from.

nLen - Number of bytes starting from offset to consider.

aOS - The output stream to write to. May not be null and is NOT closed afterwards!
