Class DefaultRepositorySystemSession

java.lang.Object

org.eclipse.aether.DefaultRepositorySystemSession

All Implemented Interfaces:

RepositorySystemSession

public final class DefaultRepositorySystemSession
extends Object
implements RepositorySystemSession

A legacy repository system session. It is usable to "derive" sessions from existing session instances (using copy-constructor), but the recommended way to derive sessions is using RepositorySystemSession.SessionBuilder.withRepositorySystemSession(RepositorySystemSession) instead.

Important: while the default constructor on this class is deprecated only, it is left only to guarantee backward compatibility with legacy code, but the default constructor should not be used anymore. Using that constructor will lead to resource leaks.

Note: This class is not thread-safe. It is assumed that the mutators get only called during an initialization phase and that the session itself is not changed once initialized and being used by the repository system. It is recommended to call setReadOnly() once the session has been fully initialized to prevent accidental manipulation of it afterward.

Constructor Details

DefaultRepositorySystemSession

@Deprecated
public DefaultRepositorySystemSession()

Deprecated.

This way of creating session should be avoided, is in place just to offer backward binary compatibility with Resolver 1.x using code, but offers reduced functionality. Use RepositorySystem.createSessionBuilder() instead.

Creates an uninitialized session. Note: The new session is not ready to use, as a bare minimum, setLocalRepositoryManager(LocalRepositoryManager) needs to be called but usually other settings also need to be customized to achieve meaningful behavior.

DefaultRepositorySystemSession

public DefaultRepositorySystemSession(Function<Runnable,Boolean> onSessionEndedRegistrar)

Creates an uninitialized session. Note: The new session is not ready to use, as a bare minimum, setLocalRepositoryManager(LocalRepositoryManager) needs to be called but usually other settings also need to be customized to achieve meaningful behavior.

Note: preferred way to create sessions is RepositorySystem.createSessionBuilder(), as then client code does not have to fiddle with session close callbacks. This constructor is meant more for testing purposes.

Since:

2.0.0

DefaultRepositorySystemSession

public DefaultRepositorySystemSession(RepositorySystemSession session)

Creates a shallow copy of the specified session. Actually, the copy is not completely shallow, all maps holding system/user/config properties are copied as well. In other words, invoking any mutator on the new session itself has no effect on the original session. Other mutable objects like the session data and cache (if any) are not copied and will be shared with the original session unless reconfigured.

Parameters:

session - The session to copy, must not be null.

Method Details

isOffline

public boolean isOffline()

Description copied from interface: RepositorySystemSession

Indicates whether the repository system operates in offline mode and avoids/refuses any access to remote repositories.

Specified by:

isOffline in interface RepositorySystemSession

Returns:

setOffline

public DefaultRepositorySystemSession setOffline(boolean offline)

Controls whether the repository system operates in offline mode and avoids/refuses any access to remote repositories.

Returns:

This session for chaining, never null.

Returns:

true if additional repositories from artifact descriptors are ignored, false to merge those with the originally specified repositories.

setIgnoreArtifactDescriptorRepositories

public DefaultRepositorySystemSession setIgnoreArtifactDescriptorRepositories(boolean ignoreArtifactDescriptorRepositories)

setReadOnly

public void setReadOnly()

Marks this session as read-only such that any future attempts to call its mutators will fail with an exception. Marking an already read-only session as read-only has no effect. The session's data and cache remain writable though.
