Examples with Aggregate org.apache.jackrabbit.vault.fs.api.Aggregate used on opensource projects

Example 1 with Aggregate

use of org.apache.jackrabbit.vault.fs.api.Aggregate in project sling by apache.

the class VltSerializationDataBuilder method findAggregateChain.

/**
     * Returns the aggregates for a specific resource
     * 
     * <p>
     * In the simplest case, a single element is returned in the chain, signalling that the aggregate is a top-level
     * one.
     * </p>
     * 
     * <p>
     * For leaf aggregates, the list contains the top-most aggregates first and ends up with the leaf-most ones.
     * </p>
     * 
     * @param resource the resource to find the aggregate chain for
     * @return a list of aggregates
     * @throws IOException
     * @throws RepositoryException
