getMaximumEncodedLength

@Nonnegative
public int getMaximumEncodedLength(@Nonnegative
 int nDecodedLen)

Description copied from interface: ICharArrayEncoder

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 ICharArrayEncoder

Specified by:

getMaximumEncodedLength in interface ICharArrayStreamEncoder

Parameters:

nDecodedLen - The decoded length. Always ≥ 0.

Returns:

The maximum encoded length. Always ≥ 0.

encode

public void encode(@Nullable
 char[] aDecodedBuffer,
 @Nonnegative
 int nOfs,
 @Nonnegative
 int nLen,
 @Nonnull @WillNotClose
 Writer aWriter)

Description copied from interface: ICharArrayStreamEncoder

Encode (part of) a char array to an Writer.

Specified by:

encode in interface ICharArrayStreamEncoder

Parameters:

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

nOfs - Offset into the char array to start from.

nLen - Number of chars starting from offset to consider.

aWriter - The writer to write to. May not be null and is NOT closed afterwards!

getMaximumDecodedLength

@Nonnegative
public int getMaximumDecodedLength(@Nonnegative
 int nEncodedLen)

Description copied from interface: ICharArrayDecoder

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

Specified by:

getMaximumDecodedLength in interface ICharArrayDecoder

Parameters:

nEncodedLen - The encoded length. Always ≥ 0.

Returns:

The maximum decoded length. Always ≥ 0.

decode

public void decode(@Nullable
 char[] aEncodedBuffer,
 @Nonnegative
 int nOfs,
 @Nonnegative
 int nLen,
 @Nonnull @WillNotClose
 Writer aWriter)

Description copied from interface: ICharArrayStreamDecoder

Decode (part of) a char array.

Specified by:

decode in interface ICharArrayStreamDecoder

Parameters:

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

nOfs - Offset into the char array to start from.

nLen - Number of chars starting from offset to consider.

aWriter - The writer to write to. May not be null and is NOT closed afterwards!
