Record Class ForeignFunctionCallResult

java.lang.Object

java.lang.Record

net.jrodolfo.java_evolution.java22.foreign_function.ForeignFunctionCallResult

Record Components:

functionName - the native function that was called

input - the Java input copied into native memory

value - the value returned to Java

javaType - the Java type used for the returned value

public record ForeignFunctionCallResult(String functionName, String input, Number value, String javaType)
extends Record

Captures the observable result of a small native function call.

The record keeps the examples easy to test without printing from the example classes. The Java type is included because foreign calls cross a boundary where C types and Java types must be mapped deliberately.

ForeignFunctionCallResult

public ForeignFunctionCallResult(String functionName,
 String input,
 Number value,
 String javaType)

Creates an instance of a ForeignFunctionCallResult record class.

Parameters:

functionName - the value for the functionName record component

input - the value for the input record component

value - the value for the value record component

javaType - the value for the javaType 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.

functionName

public String functionName()

Returns the value of the functionName record component.

Returns:

the value of the functionName record component

input

public String input()

Returns the value of the input record component.

Returns:

the value of the input record component

value

public Number value()

Returns the value of the value record component.

Returns:

the value of the value record component

javaType

public String javaType()

Returns the value of the javaType record component.

Returns:

the value of the javaType record component
