Class ModuleCompilerHelper

java.lang.Object

dev.metaschema.databind.codegen.ModuleCompilerHelper

public final class ModuleCompilerHelper
extends Object

This class provides methods to generate and dynamically compile Java code based on a Module. The newClassLoader(Path, ClassLoader) method can be used to get a ClassLoader for Java code previously generated by this class.

Method Summary

Modifier and Type	Method	Description
static IProduction	compileMetaschema(dev.metaschema.core.model.IModule module, Path classDir)	Generate and compile Java class, representing the provided Module module and its related definitions, using the default binding configuration.
static IProduction	compileModule(dev.metaschema.core.model.IModule module, Path classDir, IBindingConfiguration bindingConfiguration)	Generate and compile Java class, representing the provided Module module and its related definitions, using the provided custom bindingConfiguration.
static @Owning ClassLoader	newClassLoader(Path classDir, ClassLoader parent)	Create a new classloader capable of loading Java classes generated in the provided classDir.

Method Details

newClassLoader

@Owning
@NonNull
public static @Owning ClassLoader newClassLoader(@NonNull
 Path classDir,
 @NonNull
 ClassLoader parent)

Create a new classloader capable of loading Java classes generated in the provided classDir.

The caller owns the returned class loader and is responsible for closing it.

Parameters:

classDir - the directory where generated Java classes have been compiled

parent - the classloader to delegate to when the created class loader cannot load a class

Returns:

the new class loader

compileMetaschema

@NonNull
public static IProduction compileMetaschema(@NonNull
 dev.metaschema.core.model.IModule module,
 @NonNull
 Path classDir)
                                     throws IOException

Generate and compile Java class, representing the provided Module module and its related definitions, using the default binding configuration.

Parameters:

module - the Module module to generate Java classes for

classDir - the directory to generate the classes in

Returns:

information about the generated classes

Throws:

IOException - if an error occurred while generating or compiling the classes

compileModule

@NonNull
public static IProduction compileModule(@NonNull
 dev.metaschema.core.model.IModule module,
 @NonNull
 Path classDir,
 @NonNull
 IBindingConfiguration bindingConfiguration)
                                 throws IOException

Generate and compile Java class, representing the provided Module module and its related definitions, using the provided custom bindingConfiguration.

Parameters:

module - the Module module to generate Java classes for

classDir - the directory to generate the classes in

bindingConfiguration - configuration settings with directives that tailor the class generation

Returns:

information about the generated classes

Throws:

IOException - if an error occurred while generating or compiling the classes
