public static interface SSTableId.Builder<T extends SSTableId>

Builder that can create instances of certain implementation of SSTableId.

Method Summary

Modifier and Type	Method and Description
T	fromBytes(java.nio.ByteBuffer bytes) Creates an identifier instance from its binary representation
T	fromString(java.lang.String str) Creates an identifier instance from its string representation
java.util.function.Supplier<T>	generator(java.util.stream.Stream<SSTableId> existingIdentifiers) Creates a new generator of identifiers.
boolean	isUniqueIdentifier(java.nio.ByteBuffer bytes)
boolean	isUniqueIdentifier(java.lang.String str)

Method Detail

generator

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

Creates a new generator of identifiers. Each supplied value must be different to all the previously generated values and different to all the provided existing identifiers.

isUniqueIdentifier

boolean isUniqueIdentifier(java.lang.String str)

isUniqueIdentifier

boolean isUniqueIdentifier(java.nio.ByteBuffer bytes)

fromString

T fromString(java.lang.String str)
      throws java.lang.IllegalArgumentException

Creates an identifier instance from its string representation

Parameters:

str - 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

T fromBytes(java.nio.ByteBuffer bytes)
     throws java.lang.IllegalArgumentException

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.

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
