    queryVertexByProperties()	Query a collection of vertexes for a specific property
    queryAllAdjacentVertex(Class<?>... edgeClass)	Query a collection of all neighboring vertexes of a particular vertex, specifying one or more edge types that connect the two vertexes
    queryIncomingAdjacentVertex(Class<?>... edgeClass)	Query the set of adjacent vertexes in the direction of the incoming edge of a particular vertex, specifying one or more edge types that connect two vertexes
    queryOutgoingAdjacentVertex(Class<?>... edgeClass)	Query the set of adjacent vertexes in the direction of the edge of a particular vertex, specifying one or more edge types that connect two vertexes
    queryNeighborIdsWithHopById(int m, int n, Class<?>... edgeClass)	Query a collection of vertex ids within a specified number of hops for a particular vertex, specifying one or more edge types that connect two vertexes
    queryConnectedEdgesById(Direction direction)	Query the set of all edges associated with a particular vertex, specifying the direction and type of the edge
    queryPathFromVertex(Direction direction)	Query the collection of all paths associated with a particular vertex, specifying the direction of the edge
    queryFixedLengthPathFromVertex(Integer maxHop, Direction direction, Class<?>... edgeClass)	Query a set of fixed-length paths from a specific vertex, specifying the maximum number of steps, the direction of the edge, and the type of the edge
    queryVariableLengthPathFromVertex(Integer minHop, Integer maxHop, Direction direction, Class<?>... edgeClass)	Query a set of variable-length paths from a specific vertex, specifying the minimum number of steps, the maximum number of steps, the direction of the edge, and the type of the edge
    queryShortestPathFromSrcAndDst(Integer maxHop, Direction direction, T v2)	Query any shortest path from a specific vertex, specifying the number of steps, the direction of the edge, and the end vertex entity
    queryAllShortestPathsFromSrcAndDst(Integer maxHop, Direction direction, T v2)	Query the set of all shortest paths from this vertex, specifying the number of steps, the direction of the edge, and the end vertex entity
    queryVertexCountByTag()	Query the number of vertexes for a specific Tag

    • GraphBaseEdge:

    API	Usage instructions
    queryEdgeByType(Direction direction)	Query a set of edges of a specific type and direction
    queryEdgeWithSrcAndDstByProperties(T srcVertex, Direction direction, T dstVertex)	Query a set of edges for a particular property
    queryEdgePropertiesBySrcAndDstId()	Query a set of edges for a specific always vertex id
    queryEdgeCountByType()	Query the number of edges for a specific Type
