Method Detail

handleExternal

SVNRevision[] handleExternal(java.io.File externalPath,
                             SVNURL externalURL,
                             SVNRevision externalRevision,
                             SVNRevision externalPegRevision,
                             java.lang.String externalsDefinition,
                             SVNRevision externalsWorkingRevision)

Handles an external definition and says whether to skip it or not. This method receives external definition parameters and returns whether null to indicate that this external definition must be excluded from processing (for examle, not updated during an update), or a non- null array. This array should contain at least two SVNRevision objects [revision, pegRevision] which will be used by the operation instead of externalRevision and externalPegRevision respectively passed into this handle method.

externalWorkingRevision is always SVNRevision.UNDEFINED for update/checkout operations.

Parameters:

externalPath - path of the external to be processed

externalURL - URL of the external to be processed or null if external is about to be removed

externalRevision - default revision to checkout/copy external at or update to

externalPegRevision - default peg revision to use for checkout/update/copy of external

externalsDefinition - raw svn:externals property value

externalsWorkingRevision - current external working copy revision (relevant only for wc-to-url copying operations)

Returns:

array of SVNRevisions in form of {revision, pegRevision} or null to skip processing of this external
