Method Detail

getColumnType

OraclePgqlColumnDescriptor.Type getColumnType(int elementIdx)

Gets the column type for the result element at given position. The first element is at position 1.

Possible values are:

OraclePgqlColumnDescriptor.Type.VERTEX
OraclePgqlColumnDescriptor.Type.EDGE
OraclePgqlColumnDescriptor.Type.VALUE

Parameters:

elementIdx - the result element position

Returns:

the column type

getEdge

OracleEdge getEdge(int elementIdx)
            throws OraclePropertyGraphException

Gets the Edge object for the result element at given position. The first element is at position 1.

Parameters:

elementIdx - the result element position

Returns:

the OracleEdge oject for this result element

Throws:

OraclePropertyGraphException

getResultElements
