Constructor Details

BlockfileChecksummer

public BlockfileChecksummer(String encodedName,
 int numBytes,
 Supplier<Function<byte[],byte[]>> encoderSupplier)

Creates an instance of a BlockfileChecksummer record class.

Parameters:

encodedName - the value for the encodedName record component

numBytes - the value for the numBytes record component

encoderSupplier - the value for the encoderSupplier record component

Method Details

lengthToBytes

public byte[] lengthToBytes()

bytesToLength

public static int bytesToLength(byte[] bytes)

nameToBytes

public byte[] nameToBytes()

bytesToName

public static String bytesToName(byte[] bytes)

newEncoder

public Function<byte[],byte[]> newEncoder()

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with '=='.

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

encodedName

public String encodedName()

Returns the value of the encodedName record component.

Returns:

the value of the encodedName record component

numBytes

public int numBytes()

Returns the value of the numBytes record component.

Returns:

the value of the numBytes record component

encoderSupplier

public Supplier<Function<byte[],byte[]>> encoderSupplier()

Returns the value of the encoderSupplier record component.

Returns:

the value of the encoderSupplier record component
