Method Detail

newBranchForView

ViewManageable newBranchForView(ViewManageable version,
                                String viewName)
                                throws WTPropertyVetoException,
                                       WTException,
                                       ViewException

Creates a new version from the original version and assigns it to the specified view. The original version must not be null, and the view must be a child view of the view the original was assigned to. The classic behavior of newViewVersion is to branch from the upstream node. If we have a part with versions Rev A (Eng), Rev A.A (Mfg) (branched from Rev A (Eng)), and Rev B (Eng) (revised from Rev A (Eng)), new view version of Rev B (Eng) would result in a B.A (Mfg) branched from Rev B (Eng). This preserves all the changes from Rev A (Eng) to Rev B (Eng), but loses the changes (restructuring, etc.) made to A.A (Mfg). By setting the wt.properties entry wt.vc.views.newViewVersionClassicBehavior to false, you can change this behavior: rather than creating B.A (Mfg) from B (Eng), the new version will be created from A.A (Mfg). The result will still be B.A (Mfg), but the Mfg changes will be preserved.

Supported API: true

Parameters:

version - The version the new version is to be derived from.

viewName - The view name of the view to assign the new version to.

Returns:

ViewManageable

Throws:

WTPropertyVetoException

                                       WTException,
                                       ViewException

Creates a new version from the original version and assigns it to the specified view. The original version must not be null, and the view must be a child view of the view the original was assigned to. The classic behavior of newViewVersion is to branch from the upstream node. If we have a part with versions Rev A (Eng), Rev A.A (Mfg) (branched from Rev A (Eng)), and Rev B (Eng) (revised from Rev A (Eng)), new view version of Rev B (Eng) would result in a B.A (Mfg) branched from Rev B (Eng). This preserves all the changes from Rev A (Eng) to Rev B (Eng), but loses the changes (restructuring, etc.) made to A.A (Mfg). By setting the wt.properties entry wt.vc.views.newViewVersionClassicBehavior to false, you can change this behavior: rather than creating B.A (Mfg) from B (Eng), the new version will be created from A.A (Mfg). The result will still be B.A (Mfg), but the Mfg changes will be preserved.
