Examples with PathBuilder org.apache.sling.api.resource.path.PathBuilder used on opensource projects

Example 1 with PathBuilder

use of org.apache.sling.api.resource.path.PathBuilder in project sling by apache.

the class ResourceResolverControl method copy.

private void copy(final ResourceResolverContext context, final Resource src, final String dstPath, final List<Resource> newNodes) throws PersistenceException {
    final ValueMap vm = src.getValueMap();
    final String createPath = new PathBuilder(dstPath).append(src.getName()).toString();
    newNodes.add(this.create(context, createPath, vm));
    for (final Resource c : src.getChildren()) {
        copy(context, c, createPath, newNodes);
    }
}

Example 2 with PathBuilder

use of org.apache.sling.api.resource.path.PathBuilder in project sling by apache.

the class SlingTemplateResource method relative.

@Override
public ITemplateResource relative(final String relativeLocation) {
    final PathBuilder pathBuilder = new PathBuilder(resource.getPath());
    final String path = pathBuilder.append("..").append(relativeLocation).toString();
    final ResourceResolver resourceResolver = resource.getResourceResolver();
    final Resource relative = resourceResolver.getResource(path);
    // final Resource relative = resource.getParent().getChild(relativeLocation);
    return new SlingTemplateResource(relative);
}

Example 3 with PathBuilder

use of org.apache.sling.api.resource.path.PathBuilder in project sling by apache.

the class ResourceResolverControl method listChildren.

/**
     * This method asks all matching resource providers for the children iterators,
     * merges them, adds {@link SyntheticResource}s (see
     * {@link #getResource(String, Resource, Map, boolean)} for more details),
     * filters out the duplicates and returns the resulting iterator. All
     * transformations are done lazily, during the {@link Iterator#hasNext()}
     * invocation on the result.
