@ThreadSafe
public class Reader
extends Object

We need the full kaboodle when processing our own classes, but when processing our dependencies we only want manifest (for OSGi) and module-info.class (for JPMS)

Method Detail

reader

public static Reader reader()

reader.

Returns:

a Reader object.

setImportedTypeReducer

public Reader setImportedTypeReducer(UnaryOperator<String> importedTypeReducer)

If you pass in typeToPackageReducer(String) as a method reference then it will reduce imported types to packages.

Parameters:

importedTypeReducer - a UnaryOperator object.

Returns:

a Reader object.

setImportingTypeReducer

public Reader setImportingTypeReducer(UnaryOperator<String> importingTypeReducer)

If you pass in typeToPackageReducer(String) as a method reference then it will reduce imported types to packages.

Parameters:

importingTypeReducer - a UnaryOperator object.

Returns:

a Reader object.

typeToPackageReducer

public static String typeToPackageReducer(String type)

typeToPackageReducer.

Parameters:

type - a String object.

Returns:

a String object.

ignoreAnnotations

public Reader ignoreAnnotations()

addByteCodeListener

public Reader addByteCodeListener(Consumer<byte[]> listener)

Only invoked when processing a JAR (i.e. using processJar(Path), processJar(InputStream) or processJar(JarInputStream)), not when invoking processClass(byte[])

Parameters:

listener - a Consumer object.

Returns:

a Reader object.

setJarEntryListener

public Reader setJarEntryListener(BiConsumer<JarEntry,InputStream> listener)

For entries other than classes and Manifest

Parameters:

listener - a BiConsumer object.
