public RepositorySourceCapabilities(boolean supportsSameNameSiblings,
                                    boolean supportsUpdates,

                                    boolean supportsReferences)

Method Detail

supportsSameNameSiblings

public boolean supportsSameNameSiblings()

Return whether the source supports same name siblings. If not, then no two siblings may share the same name.

Returns:

true if same name siblings are supported, or false otherwise

supportsUpdates

public boolean supportsUpdates()

Return whether the source supports updates. This may be true, even though a particular connection made on behalf of a user may not have any update privileges. In other words, returning false implies that no connections would allow updates to the content.

Returns:

true if updates are supported, or false if the source only supports reads.

supportsReferences

public boolean supportsReferences()

Return whether the source supports references by identifiers.

Returns:

true if references are supported, or false otherwise

supportsEvents

public boolean supportsEvents()

Return whether the source supports publishing change events.

Returns:

true if events are supported, or false if the source is not capable of generating events

supportsCreatingWorkspaces

public boolean supportsCreatingWorkspaces()

Return whether the source supports creating workspaces through the connector.

Returns:

true if creating workspaces is supported, or false if the source is not capable of creating workspaces
