Method Summary

Modifier and Type	Method	Description
default char[]	getEncoded(char[] aDecodedBuffer)	Encode a char array.
char[]	getEncoded(char[] aDecodedBuffer, int nOfs, int nLen)	Encode a char array.
default char[]	getEncoded(String sDecoded)	Encode the passed string.
default int	getMaximumEncodedLength(int nDecodedLen)	Get the maximum encoded length based on the provided decoded length.

Method Detail

getMaximumEncodedLength

@Nonnegative
default int getMaximumEncodedLength(@Nonnegative
                                    int nDecodedLen)

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".

Parameters:

nDecodedLen - The decoded length. Always ≥ 0.

Returns:

The maximum encoded length. Always ≥ 0.

getEncoded

@Nullable
@ReturnsMutableCopy
default char[] getEncoded(@Nullable
                          char[] aDecodedBuffer)

Encode a char array.

Specified by:

getEncoded in interface IEncoder<char[],char[]>

Parameters:

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

Returns:

The encoded char array or null if the parameter was null.

Throws:

EncodeException - In case something goes wrong

getEncoded

@Nullable
@ReturnsMutableCopy
char[] getEncoded(@Nullable
                  char[] aDecodedBuffer,
                  @Nonnegative
                  int nOfs,
                  @Nonnegative
                  int nLen)

Encode a char array.

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.

Returns:

The encoded char array or null if the parameter was null.

Throws:

EncodeException - In case something goes wrong

getEncoded

@Nullable
@ReturnsMutableCopy
default char[] getEncoded(@Nullable
                          String sDecoded)

Encode the passed string.

Parameters:

sDecoded - The string to be encoded. May be null.

Returns:

null if the input string is null.

Throws:

EncodeException - In case something goes wrong
