Class SymbolsLongConverter

java.lang.Object

net.openhft.chronicle.wire.converter.SymbolsLongConverter

All Implemented Interfaces:

LongConverter

public class SymbolsLongConverter
extends Object
implements LongConverter

A specialized implementation of the LongConverter interface for converting long values to and from strings using arbitrary bases, specifically those not necessarily in powers of two.

This converter efficiently manages conversion using provided symbols, allowing flexible and adaptable encoding and decoding processes.

Constructor Detail

SymbolsLongConverter

public SymbolsLongConverter(String symbols)

Initializes a new instance with a given set of symbols.

Parameters:

symbols - A string containing unique symbols for conversion.

Method Detail

maxParseLength

public int maxParseLength()

Description copied from interface: LongConverter

Returns the maximum number of characters that this converter can parse.

Specified by:

maxParseLength in interface LongConverter

Returns:

The maximum parse length, or Integer.MAX_VALUE if there's no limit.

parse

public long parse(CharSequence text)

Parses a sequence of characters into a long value.

Specified by:

parse in interface LongConverter

Parameters:

text - the character sequence to parse.

Returns:

the parsed long value.

Throws:

IllegalArgumentException - if the character sequence contains unexpected characters or its length exceeds the maximum allowable length.

parse

public long parse(CharSequence text,
                  int beginIndex,
                  int endIndex)

Parses a part of a sequence of characters into a long value.

Specified by:

parse in interface LongConverter

Parameters:

text - the character sequence to parse.

beginIndex - the beginning index, inclusive.

endIndex - the ending index, exclusive.

Returns:

the parsed long value.

Throws:

IllegalArgumentException - if the character sequence contains unexpected characters, or if any of the indices are invalid or the sub-sequence length exceeds the maximum allowable length.

append

public void append(StringBuilder text,
                   long value)

Appends a long value to a StringBuilder.

Specified by:

append in interface LongConverter

Parameters:

text - the StringBuilder to append to

value - the long value to append

append

public void append(net.openhft.chronicle.bytes.Bytes<?> text,
                   long value)

Appends a long value to a Bytes object.

Specified by:

append in interface LongConverter

Parameters:

text - the Bytes object to append to

value - the long value to append

addEncode

public void addEncode(char alias,
                      char as)

Adds an alias character for encoding. The alias character will be treated the same as the "as" character in the encoding process.

Specified by:

addEncode in interface LongConverter

Parameters:

alias - The character to treat as an alias.

as - The character that the alias should be treated as.
