Record Class MethodHandleSpec

java.lang.Object

java.lang.Record

org.elasticsearch.injection.spec.MethodHandleSpec

All Implemented Interfaces:

InjectionSpec

public record MethodHandleSpec(Class<?> requestedType, MethodHandle methodHandle, List<ParameterSpec> parameters)
extends Record
implements InjectionSpec

Indicates that a type should be instantiated by calling the given MethodHandle.

Design note: the intent is that the semantics are fully specified by this record, and no additional reflection logic is required to determine how the object should be injected. Roughly speaking: all the reflection should be finished, and the results should be stored in this object.

Constructor Details

MethodHandleSpec

public MethodHandleSpec(Class<?> requestedType,
 MethodHandle methodHandle,
 List<ParameterSpec> parameters)

Creates an instance of a MethodHandleSpec record class.

Parameters:

requestedType - the value for the requestedType record component

methodHandle - the value for the methodHandle record component

parameters - the value for the parameters record component

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.

requestedType

public Class<?> requestedType()

Returns the value of the requestedType record component.

Specified by:

requestedType in interface InjectionSpec

Returns:

the value of the requestedType record component

methodHandle

public MethodHandle methodHandle()

Returns the value of the methodHandle record component.

Returns:

the value of the methodHandle record component

parameters

public List<ParameterSpec> parameters()

Returns the value of the parameters record component.

Returns:

the value of the parameters record component
