Module jdk.incubator.jextract

Package jdk.incubator.jextract

Class JextractTool

java.lang.Object

jdk.incubator.jextract.JextractTool

public final class JextractTool
extends Object

Simple extraction tool which generates a minimal Java API. Such an API consists mainly of static methods, where for each native function a static method is added which calls the underlying native method handles. Similarly, for struct fields and global variables, static accessors (getter and setter) are generated on top of the underlying memory access var handles. For each struct, a static layout field is generated.
