Method Detail

getTable

public TranslatableTable getTable(RelDataTypeFactory typeFactory,
                         List<SqlNode> operandList)

Returns the table in this UDF, or null if there is no table.

convertArguments

public static List<Object> convertArguments(RelDataTypeFactory typeFactory,
                            List<SqlNode> operandList,
                            Function function,
                            SqlIdentifier opName,
                            boolean failOnNonLiteral)

Converts arguments from SqlNode to java object format.

Parameters:

typeFactory - type factory used to convert the arguments

operandList - input arguments

function - target function to get parameter types from

opName - name of the operator to use in error message

failOnNonLiteral - true when conversion should fail on non-literal

Returns:

converted list of arguments
