Package io.axoniq.framework.messaging.transformation

Record Class FromMatcher.PredicateBased

java.lang.Object

java.lang.Record

io.axoniq.framework.messaging.transformation.FromMatcher.PredicateBased

Record Components:

predicate - the source predicate

declaredFromTypes - the qualified names the predicate is restricted to; empty means every candidate

All Implemented Interfaces:

FromMatcher

Enclosing interface:

FromMatcher

public static record FromMatcher.PredicateBased(Predicate<MessageType> predicate, Set<QualifiedName> declaredFromTypes)
extends Record
implements FromMatcher

Predicate-source matcher: matches any MessageType the predicate accepts. When declaredFromTypes is non-empty it acts as a pre-filter: only events whose MessageType.qualifiedName() is one of those names ever reach the predicate. An empty set evaluates the predicate against every candidate.

Constructor Details

PredicateBased

public PredicateBased(Predicate<MessageType> predicate,
 Set<QualifiedName> declaredFromTypes)

Creates an instance of a PredicateBased record class.

Parameters:

predicate - the value for the predicate record component

declaredFromTypes - the value for the declaredFromTypes record component

Method Details

matches

public boolean matches(MessageType candidate)

Description copied from interface: FromMatcher

Answers whether the given candidate type satisfies this matcher.

Specified by:

matches in interface FromMatcher

Parameters:

candidate - the message's MessageType

Returns:

true when the candidate matches

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.

predicate

public Predicate<MessageType> predicate()

Returns the value of the predicate record component.

Returns:

the value of the predicate record component

declaredFromTypes

public Set<QualifiedName> declaredFromTypes()

Returns the value of the declaredFromTypes record component.

Returns:

the value of the declaredFromTypes record component
