Record Class Transaction.Condition

java.lang.Object

java.lang.Record

com.loomcache.server.transaction.Transaction.Condition

Record Components:

key - the key to check (must not be null)

type - the type of condition to evaluate (must not be null)

expected - the expected value for comparison (can be null)

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

Enclosing class:

Transaction

public static record Transaction.Condition(String key, Transaction.ConditionType type, @Nullable Object expected, @Nullable String mapName)
extends Record

Condition to evaluate in the IF branch of a transaction.

Since:

1.0

Constructor Summary

Constructors

Constructor	Description
Condition(String key, Transaction.ConditionType type, @Nullable Object expected)	Convenience constructor for single-map transactions — defaults mapName() to null.
Condition(String key, Transaction.ConditionType type, @Nullable Object expected, @Nullable String mapName)	Compact constructor validating key and type.

Method Summary

Modifier and Type	Method	Description
final boolean	equals(Object o)	Indicates whether some other object is "equal to" this one.
@Nullable Object	expected()	Returns the value of the expected record component.
final int	hashCode()	Returns a hash code value for this object.
String	key()	Returns the value of the key record component.
@Nullable String	mapName()	Returns the value of the mapName record component.
final String	toString()	Returns a string representation of this record class.
Transaction.ConditionType	type()	Returns the value of the type record component.

Constructor Details

Condition

public Condition(String key,
 Transaction.ConditionType type,
 @Nullable Object expected,
 @Nullable String mapName)

Compact constructor validating key and type.

Throws:

NullPointerException - if key or type is null

Condition

public Condition(String key,
 Transaction.ConditionType type,
 @Nullable Object expected)

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.

key

public String key()

Returns the value of the key record component.

Returns:

the value of the key record component

type

public Transaction.ConditionType type()

Returns the value of the type record component.

Returns:

the value of the type record component

expected

public @Nullable Object expected()

Returns the value of the expected record component.

Returns:

the value of the expected record component

mapName

public @Nullable String mapName()

Returns the value of the mapName record component.

Returns:

the value of the mapName record component
