equals	back to summary
public final boolean equals(Object o) Implements abstract java.lang.Record.equals. Doc from java.lang.Record.equals. Indicates whether some other object is "equal to" this one. In addition to the general contract of `Object.equals`, record classes must further obey the invariant that when a record instance is "copied" by passing the result of the record component accessor methods to the canonical constructor, as follows: R copy = new R(r.c1(), r.c2(), ..., r.cn()); then it must be the case that `r.equals(copy)`.

find	back to summary
public Optional<ModuleReference> find(String name) Implements java.lang.module.ModuleFinder.find. Doc from java.lang.module.ModuleFinder.find. Finds a reference to a module of a given name. A `ModuleFinder` provides a consistent view of the modules that it locates. If `find` is invoked several times to locate the same module (by name) then it will return the same result each time. If a module is located then it is guaranteed to be a member of the set of modules returned by the `findAll` method. Annotations @Override

public Optional<ModuleReference> find(String name)

hashCode	back to summary
public final int hashCode() Implements abstract java.lang.Record.hashCode. Doc from java.lang.Record.hashCode. Returns a hash code value for the record. Obeys the general contract of `Object.hashCode`. For records, hashing behavior is constrained by the refined contract of `Record.equals`, so that any two records created from the same components must have the same hash code.

public final int hashCode()

Implements abstract java.lang.Record.hashCode.

Doc from java.lang.Record.hashCode.

Returns a hash code value for the record. Obeys the general contract of Object.hashCode. For records, hashing behavior is constrained by the refined contract of Record.equals, so that any two records created from the same components must have the same hash code.

public ProgramDescriptor programDescriptor() Record Component getter of programDescriptor.

toString back to summary

toString	back to summary
public final String toString() Implements abstract java.lang.Record.toString. Doc from java.lang.Record.toString. Returns a string representation of the record. In accordance with the general contract of `Object#toString()`, the `toString` method returns a string that "textually represents" this record. The result should be a concise but informative representation that is easy for a person to read. In addition to this general contract, record classes must further participate in the invariant that any two records which are equal must produce equal strings. This invariant is necessarily relaxed in the rare case where corresponding equal component values might fail to produce equal strings for themselves.

close	back to summary
public void close() Implements java.lang.module.ModuleReader.close. Doc from java.lang.module.ModuleReader.close. Closes the module reader. Once closed then subsequent calls to locate or read a resource will fail by throwing `IOException`. A module reader is not required to be asynchronously closeable. If a thread is reading a resource and another thread invokes the close method, then the second thread may block until the read operation is complete.

list back to summary

list	back to summary
public Stream<String> list() throws IOException Implements java.lang.module.ModuleReader.list. Doc from java.lang.module.ModuleReader.list. Lists the contents of the module, returning a stream of elements that are the names of all resources in the module. Whether the stream of elements includes names corresponding to directories in the module is module reader specific. In lazy implementations then an `IOException` may be thrown when using the stream to list the module contents. If this occurs then the `IOException` will be wrapped in an `java.io.UncheckedIOException` and thrown from the method that caused the access to be attempted. The returned stream may contain references to one or more open directories in the module. The directories are closed by closing the stream. The behavior of the stream when used after the module reader is closed is implementation specific and therefore not specified. Exceptions IOException: If an I/O error occurs or the module reader is closed
