How to get EdgeIteratorState from EdgeID

Oh you need to call next() on the edge iterator, before this its not even in a sane state. With every call to next() you get the next edge and this way you can traverse all edges.

Getting all edges:

AllEdgesIterator allEdges = graph.getAllEdges();
while (allEdges.next()) {
    int adjNode = allEdges.getAdjNode();
    int baseNode = allEdges.getBaseNode();
    int edgeId = allEdges.getEdge();
}

Getting all edges adjacent to a certain node:

EdgeExplorer exp = graph.getEdgeExplorer();
EdgeIterator iter = exp.setBaseNode(yourNode);
while (iter.next()) {
    int adjNode = iter.getAdjNode();
    int baseNode = iter.getBaseNode();
    int edgeId = iter.getEdge();
}

Using the Path from the route calculation you can also get all the nodes or edge iterator states on this path: path.calcNodes() and path.calcEdges(). Take a look at the code it should be easy to see.
