ISelfCompiled (Manifold :: Core 2026.1.6 API)

All Known Subinterfaces:

ITypeManifold

All Known Implementing Classes:

JavaTypeManifold, ResourceFileTypeManifold, UrlTypeManifold
```
public interface ISelfCompiled
```
A self-compiled type manifold provides its own Java bytecode for some or all of its types. Thus, its implementation of ITypeManifold.contribute(javax.tools.JavaFileManager.Location, java.lang.String, boolean, java.lang.String, javax.tools.DiagnosticListener<javax.tools.JavaFileObject>) is typically a stub limited to member declarations. So, instead of using javac to compile your source to disk, you use it to parse your stub to allow other types to make references to your type. But the bytecode for your type comes from your implementation of compile(String).

Method Summary

All Methods Instance Methods Default Methods
Modifier and Type	Method	Description
`default byte[]`	`compile(String fqn)`	Instructs a self-compiling type manifold to compile `fqn` and return resulting Java byte-code.
`default boolean`	`isSelfCompile(String fqn)`	Tests if a type `fqn` is self-compiled where subsequent calls to `parse(String)` and `compile(String)` are necessary to compile the type to bytecode.
`default void`	`parse(String fqn)`	Signal this type manifold to fully parse the type corresponding with `fqn` and attach parse errors/warnings to the source file, for example using `IssueReporter`<`JavaFileObject`>.

- Method Detail
  - isSelfCompile
```
default boolean isSelfCompile(String fqn)
```
    Tests if a type fqn is self-compiled where subsequent calls to parse(String) and compile(String) are necessary to compile the type to bytecode.
    
    Parameters:
    
    fqn - The fully qualified name of the type.
    
    Returns:
    
    true if the type corresponding with fqn is self-compiled.
  - parse
```
default void parse(String fqn)
```
    Signal this type manifold to fully parse the type corresponding with fqn and attach parse errors/warnings to the source file, for example using IssueReporter<JavaFileObject>.
    For instance, the Gosu language manifold has its own bytecode compiler and handles this call by fully parsing fqn. Note this call is made immediately before the Java compiler's attribution phase, which makes it ok for member definitions and such to fully resolve.
    
    Parameters:
    
    fqn - The fully qualified name of the type to parse.
  - compile
```
default byte[] compile(String fqn)
```
    Instructs a self-compiling type manifold to compile fqn and return resulting Java byte-code. Note this call is only made if no errors were attached during parse(String).
    
    Parameters:
    
    fqn - The fully qualified name of the type to compile.
