  From the work of Lian, Liu, and Yau on "Mirror Principle", in the explicit
computation of the Euler data $Q=\{Q_0, Q_1, ... \}$ for an equivariant
concavex bundle ${\cal E}$ over a toric manifold, there are two places the
structure of the bundle comes into play: (1) the multiplicative characteric
class $Q_0$ of $V$ one starts with, and (2) the splitting type of ${\cal E}$.
Equivariant bundles over a toric manifold has been classified by Kaneyama,
using data related to the linearization of the toric action on the base toric
manifold. In this article, we relate the splitting type of ${\cal E}$ to the
classifying data of Kaneyama. From these relations, we compute the splitting
type of a couple of nonsplittable equivariant vector bundles over toric
manifolds that may be of interest to string theory and mirror symmetry. A code
in Mathematica that carries out the computation of some of these examples is
attached.
