Method Detail

generator

public java.util.function.Supplier<SequenceBasedSSTableId> generator(java.util.stream.Stream<SSTableId> existingIdentifiers)

Generates a sequential number to represent an sstables identifier. The first generated identifier will be greater by one than the largest generation number found across the provided existing identifiers.

Specified by:

generator in interface SSTableId.Builder<SequenceBasedSSTableId>

isUniqueIdentifier

public boolean isUniqueIdentifier(java.lang.String str)

Specified by:

isUniqueIdentifier in interface SSTableId.Builder<SequenceBasedSSTableId>

isUniqueIdentifier

public boolean isUniqueIdentifier(java.nio.ByteBuffer bytes)

Specified by:

isUniqueIdentifier in interface SSTableId.Builder<SequenceBasedSSTableId>

fromString

public SequenceBasedSSTableId fromString(java.lang.String token)
                                  throws java.lang.IllegalArgumentException

Description copied from interface: SSTableId.Builder

Creates an identifier instance from its string representation

Specified by:

fromString in interface SSTableId.Builder<SequenceBasedSSTableId>

Parameters:

token - string representation as returned by SSTableId.toString()

Throws:

java.lang.IllegalArgumentException - when the provided string is not a valid string representation of the identifier

fromBytes

public SequenceBasedSSTableId fromBytes(java.nio.ByteBuffer bytes)
                                 throws java.lang.IllegalArgumentException

Description copied from interface: SSTableId.Builder

Creates an identifier instance from its binary representation

The method expects the identifier is encoded in all remaining bytes of the buffer. The method does not move the pointer of the buffer.

Specified by:

fromBytes in interface SSTableId.Builder<SequenceBasedSSTableId>

Parameters:

bytes - binary representation as returned by SSTableId.asBytes()

Throws:

java.lang.IllegalArgumentException - when the provided bytes are not a valid binary representation of the identifier
