Class IdentifierLongConverter

java.lang.Object

net.openhft.chronicle.wire.IdentifierLongConverter

All Implemented Interfaces:

LongConverter

public class IdentifierLongConverter
extends Object
implements LongConverter

An identifier that acts as a base 66 string of up to 10 characters, or a nanosecond timestamp for dates from 2019-09-14.

The base 66 encoding support 0-9, A-Z, a-z, period, underscore, tilde and caret. Leading zeros are truncated.

As this is intended for timestamps based on the wall clock, these shouldn't conflict.

Negative ids are reserved for application specific encodings.

Method Detail

parse

public long parse(CharSequence text)

Parses the provided CharSequence into a long identifier. The parsing behavior changes depending on the length of the CharSequence.

Specified by:

parse in interface LongConverter

Parameters:

text - the CharSequence to parse

Returns:

the parsed long identifier

append

public void append(StringBuilder text,
                   long value)

Appends a long identifier to a provided StringBuilder instance. The behavior changes depending on the magnitude of the identifier.

Specified by:

append in interface LongConverter

Parameters:

text - the StringBuilder to append the identifier to

value - the long identifier

append

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

Appends a long identifier to a provided Bytes instance. The behavior changes depending on the magnitude of the identifier.

Specified by:

append in interface LongConverter

Parameters:

bytes - the Bytes to append the identifier to

value - the long identifier

maxParseLength

public int maxParseLength()

Returns the maximum length of the CharSequence that this converter is able to parse, which in this case is the maximum parse length of the NanoTimestampLongConverter.

Specified by:

maxParseLength in interface LongConverter

Returns:

the maximum parse length
