A ModuleExposer provides access to the attributes of a module defined in Java (a built-in or extension module). These are primarily the MethodDefs derived from annotated methods in the defining class. It is normally obtained by a call to Exposer#exposeModule(Class).

pack-priv ModuleExposer()

Method Detail

exposeback to summary
pack-priv void expose(Class<?> definingClass)

Build the result from the defining class.

Parameters
definingClass:Class<?>

to scan for definitions

getMethodDefsback to summary
pack-priv ModuleDef.MethodDef[] getMethodDefs(MethodHandles.Lookup lookup) throws InterpreterError

From the methods discovered by introspection of the class, return an array of MethodDefs. This array will normally be part of a ModuleDef from which the dictionary of each instance of the module will be created. A MethodDef relies on MethodHandle, so a lookup object must be provided with the necessary access to the defining class.

Parameters
lookup:MethodHandles.Lookup

authorisation to access methods

Returns:ModuleDef.MethodDef[]

method definitions

Exceptions
InterpreterError:
on lookup prohibited
kindback to summary
pack-priv ScopeKind kind()

Implements abstract org.python.core.Exposer.kind.

Returns:ScopeKind

pack-priv void scanJavaMethods(Class<?> definingClass) throws InterpreterError

Overrides org.python.core.Exposer.scanJavaMethods.

For a Python module defined in Java, add to specs, the methods found in the given defining class and annotated for exposure.

Parameters
definingClass:Class<?>

to introspect for definitions
