VertexArray (Grape Java SDK 0.28.0 API)

Type Parameters:

T - vertex data type.

VID - vertex id type.

All Superinterfaces:

com.alibaba.fastffi.CXXPointer, com.alibaba.fastffi.FFIPointer, FFIType, Serializable

All Known Implementing Classes:

VertexArray_cxx_0xbe45efc3, VertexArray_cxx_0xd8921725, VertexArray_cxx_0xd8bd4666
```
public interface VertexArray<VID,T>
extends com.alibaba.fastffi.FFIPointer, com.alibaba.fastffi.CXXPointer
```
Vertex Array grape::VertexArray. An array which each slot binds to a vertex. Different from GSVertexArray, this class VID_T as a template parameter rather than fixed to int64_t.
In c++ the first type param is VertexRange, so be careful when specify templates.
