Record Class Transaction.Operation

java.lang.Object

java.lang.Record

com.loomcache.server.transaction.Transaction.Operation

Record Components:

type - the type of operation (must not be null)

key - the key to operate on (must not be null)

value - the value for PUT operations (null for DELETE/GET)

mapName - optional logical-map override for cross-group atomic batches where different operations target different maps within the same Raft group. When null, the operation applies to the group's single logical map recorded on the enclosing ReplicatedTransactionCommand.

Enclosing class:

Transaction

public static record Transaction.Operation(Transaction.OperationType type, String key, @Nullable String value, @Nullable String mapName)
extends Record

Operation to execute in the THEN or ELSE branch of a transaction.

Constructor Details

Operation

public Operation(Transaction.OperationType type,
 String key,
 @Nullable String value,
 @Nullable String mapName)

Compact constructor validating type and key.

Throws:

NullPointerException - if type or key is null

Operation

public Operation(Transaction.OperationType type,
 String key,
 @Nullable String value)

Convenience constructor for single-map transactions — defaults mapName() to null.

Method Details

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. All components in this record class are compared with Objects::equals(Object,Object).

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.

type

public Transaction.OperationType type()

Returns the value of the type record component.

Returns:

the value of the type record component

key

public String key()

Returns the value of the key record component.

Returns:

the value of the key record component

value

public @Nullable String value()

Returns the value of the value record component.

Returns:

the value of the value record component

mapName

public @Nullable String mapName()

Returns the value of the mapName record component.

Returns:

the value of the mapName record component
