Class ContextualSnapshotVersionFilter

java.lang.Object

org.eclipse.aether.util.graph.version.ContextualSnapshotVersionFilter

All Implemented Interfaces:

VersionFilter

public final class ContextualSnapshotVersionFilter
extends java.lang.Object
implements VersionFilter

A version filter that blocks "*-SNAPSHOT" versions if the root artifact of the dependency graph is not a snapshot. Alternatively, this filter can be forced to always ban snapshot versions by setting the boolean configuration property CONFIG_PROP_ENABLE to true.

Field Detail

CONFIG_PROP_ENABLE

public static final java.lang.String CONFIG_PROP_ENABLE

The key in the repository session's configuration properties used to store a Boolean flag whether this filter should be forced to ban snapshots. By default, snapshots are only filtered if the root artifact is not a snapshot.

public ContextualSnapshotVersionFilter()

Creates a new instance of this version filter.

isEnabled

private boolean isEnabled(RepositorySystemSession session)

filterVersions

public void filterVersions(VersionFilter.VersionFilterContext context)

Description copied from interface: VersionFilter

Filters the available versions for a given dependency. Implementations will usually call context.iterator() to inspect the available versions and use Iterator.remove() to delete unacceptable versions. If no versions remain after all filtering has been performed, the dependency collection process will automatically fail, i.e. implementations need not handle this situation on their own.

Specified by:

filterVersions in interface VersionFilter

Parameters:

context - The version filter context, must not be null.

deriveChildFilter

public VersionFilter deriveChildFilter(DependencyCollectionContext context)

Description copied from interface: VersionFilter

Derives a version filter for the specified collection context. The derived filter will be used to handle version ranges encountered in child dependencies of the current node. When calculating the child filter, implementors are strongly advised to simply return the current instance if nothing changed to help save memory.

Specified by:

deriveChildFilter in interface VersionFilter

Parameters:

context - The dependency collection context, must not be null.

Returns:

The version filter for the target node or null if versions should not be filtered any more.

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object
