WinAggResultContext (Apache Calcite API)

All Superinterfaces:

AggResetContext, AggResultContext, NestedBlockBuilder, WinAggFrameContext, WinAggFrameResultContext

All Known Subinterfaces:

WinAggAddContext

All Known Implementing Classes:

WinAggAddContextImpl, WinAggResultContextImpl
```
public interface WinAggResultContext
extends AggResultContext, WinAggFrameResultContext
```
Information for a call to AggImplementor.implementResult(AggContext, AggResultContext).
Typically, the aggregation implementation will convert AggResetContext.accumulator() to the resulting value of the aggregation. The implementation MUST NOT destroy the contents of AggResetContext.accumulator().

- Method Detail
  - rexArguments
```
java.util.List<RexNode> rexArguments()
```
    Returns RexNode representation of arguments. This can be useful for manual translation of required arguments with different NullPolicy.
    
    Returns:
    
    RexNode representation of arguments
  - arguments
```
java.util.List<Expression> arguments(Expression rowIndex)
```
    Returns Linq4j form of arguments. The resulting value is equivalent to rowTranslator().translateList(rexArguments()). This is handy if you need just operate on argument.
    
    Parameters:
    
    rowIndex - index of the requested row. The index must be in range of partition's startIndex and endIndex.
    
    Returns:
    
    Linq4j form of arguments of the particular row
