Class Base85LongConverter

java.lang.Object

net.openhft.chronicle.wire.AbstractLongConverter

net.openhft.chronicle.wire.Base85LongConverter

All Implemented Interfaces:

LongConverter

public class Base85LongConverter
extends AbstractLongConverter

Provides a Base85 encoding scheme, converting long values to a string representation. NOTE: This is intended for encoding numbers into text so that small non-negative numbers produce short strings. Notably, leading zero are truncated. In particular, 0 is encoded as an empty string.

If you need to encode text as a long value, refer to ShortTextLongConverter.

Base85 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It uses a set of 85 printable characters to represent the data, which can result in a more compact representation compared to Base64, especially for larger data sizes.

This implementation uses a custom character set that includes punctuation, numbers, uppercase letters, lowercase letters, and special characters, ensuring a wider range of encoded values.

Field Detail

MAX_LENGTH

public static final int MAX_LENGTH

Defines the maximum length of strings that can be parsed by this converter. The value is set to 10, considering the encoding efficiency of Base85.

INSTANCE

public static final Base85LongConverter INSTANCE

Provides a readily available instance of Base85LongConverter for ease of use. This shared instance simplifies the usage pattern by avoiding repeated instantiation.

Method Detail

maxParseLength

public int maxParseLength()

Returns the maximum number of characters that can be parsed.

Specified by:

maxParseLength in interface LongConverter

Overrides:

maxParseLength in class AbstractLongConverter

Returns:

the maximum length for the parsed string

allSafeChars

public boolean allSafeChars()

Indicates whether all characters in the custom Base85 character set are safe for the given output context. In this implementation, not all characters are considered safe.

Returns:

always false, denoting that not all characters are safe for all contexts.
