Class ModulePathInfo

java.lang.Object

io.github.classgraph.ModulePathInfo

public class ModulePathInfo
extends Object

Information on the module path. Note that this will only include module system parameters actually listed in commandline arguments -- in particular this does not include classpath elements from the traditional classpath, or system modules.

Field Details

modulePath

public final Set<String> modulePath

The module path provided on the commandline by the --module-path or -p switch, as an ordered set of module names, in the order they were listed on the commandline.

Note that some modules (such as system modules) will not be in this set, as they are added to the module system automatically by the runtime. Call ClassGraph.getModules() or ScanResult.getModules() to get all modules visible at runtime.

addModules

public final Set<String> addModules

The modules added to the module path on the commandline using the --add-modules switch, as an ordered set of module names, in the order they were listed on the commandline. Note that valid module names include ALL-DEFAULT, ALL-SYSTEM, and ALL-MODULE-PATH (see JEP 261 for info).

patchModules

public final Set<String> patchModules

The module patch directives listed on the commandline using the --patch-module switch, as an ordered set of strings in the format <module>=<file>, in the order they were listed on the commandline.

addExports

public final Set<String> addExports

The module exports directives added on the commandline using the --add-exports switch, as an ordered set of strings in the format <source-module>/<package>=<target-module>(,<target-module>)*, in the order they were listed on the commandline. Additionally, if this ModulePathInfo object was obtained from ScanResult.getModulePathInfo() rather than ClassGraph.getModulePathInfo(), any additional Add-Exports entries found in manifest files during classpath scanning will be appended to this list, in the format <source-module>/<package>=ALL-UNNAMED.

addOpens

public final Set<String> addOpens

The module opens directives added on the commandline using the --add-opens switch, as an ordered set of strings in the format <source-module>/<package>=<target-module>(,<target-module>)*, in the order they were listed on the commandline. Additionally, if this ModulePathInfo object was obtained from ScanResult.getModulePathInfo() rather than ClassGraph.getModulePathInfo(), any additional Add-Opens entries found in manifest files during classpath scanning will be appended to this list, in the format <source-module>/<package>=ALL-UNNAMED.

addReads

public final Set<String> addReads

The module reads directives added on the commandline using the --add-reads switch, as an ordered set of strings in the format <source-module>=<target-module>, in the order they were listed on the commandline.
