Method Detail

isAlive

boolean isAlive()

Checks if this dispatcher is alive, i.e. supports modules.

Returns:

true if modules are supported on the current VM.

moduleOf

JavaModule moduleOf(java.lang.Class<?> type)

Extracts the Java Module for the provided class or returns null if the current VM does not support modules.

Parameters:

type - The type for which to extract the module.

Returns:

The class's Module or null if the current VM does not support modules.

isNamed

boolean isNamed(java.lang.Object module)

Returns true if the supplied module is named.

Parameters:

module - The java.lang.Module to check for the existence of a name.

Returns:

true if the supplied module is named.

getName

java.lang.String getName(java.lang.Object module)

Returns the module's name.

Parameters:

module - The java.lang.Module to check for its name.

Returns:

The module's (implicit or explicit) name.

getResourceAsStream

java.io.InputStream getResourceAsStream(java.lang.Object module,
                                        java.lang.String name)

Returns a resource stream for this module for a resource of the given name or null if such a resource does not exist.

Parameters:

module - The java.lang.Module instance to apply this method upon.

name - The name of the resource.

Returns:

An input stream for the resource or null if it does not exist.

getClassLoader

java.lang.ClassLoader getClassLoader(java.lang.Object module)

Returns the module's class loader.

Parameters:

module - The java.lang.Module

Returns:

The module's class loader.

canRead

boolean canRead(java.lang.Object source,
                java.lang.Object target)

Checks if the source module can read the target module.

Parameters:

source - The source module.

target - The target module.

Returns:

true if the source module can read the target module.

addReads

void addReads(java.lang.instrument.Instrumentation instrumentation,
              java.lang.Object source,
              java.lang.Object target)

Adds a read-edge from the source to the target module.

Parameters:

instrumentation - The instrumentation instance to use for adding the edge.

source - The source module.

target - The target module.
