• String OP_SORT — The "sort" operation name.

• String OP_LIMIT — The "limit" operation name.

Constructor

This builder creates a function-chain operation with an optional expression, inputs, outputs, and parameters.

Java

FunctionChainOp.builder()
    .op(String op)
    .expr(FunctionChainExpr expr)
    .inputs(List<String> inputs)
    .outputs(List<String> outputs)
    .params(Map<String, FunctionParamValue> params)
    .build()

BUILDER METHODS:

• op(String op)

  The operation name, e.g. "map", "sort", "limit".

• expr(FunctionChainExpr expr)

• inputs(List<String> inputs)

  The input columns of this operation.

• outputs(List<String> outputs)

  The output columns of this operation.

• params(Map<String, FunctionParamValue> params)

  The named parameters of this operation. See FunctionParamValue.

RETURN TYPE:

FunctionChainOp

METHODS:

  Returns the operation name.

• FunctionChainExpr getExpr()

  Returns the attached function expression.

• List<String> getInputs()

  Returns the input columns of this operation.

• List<String> getOutputs()

  Returns the output columns of this operation.

• Map<String, FunctionParamValue> getParams()

Example

Java

FunctionChainOp op = FunctionChainOp.builder()
        .op(FunctionChainOp.OP_SORT)
        .inputs(Collections.singletonList("$score"))
