Method Summary

All Methods Static Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`static int`	`expressionsInFilter(java.util.List<org.apache.beam.vendor.calcite.v1_40_0.org.apache.calcite.rex.RexNode> filterNodes)`	Count a number of `RexNode`s involved in all supported filters.
`java.util.List<org.apache.beam.vendor.calcite.v1_40_0.org.apache.calcite.rex.RexNode>`	`getNotSupported()`	Identify parts of a predicate that are not supported by the IO push-down capabilities to be preserved in a `Calc` following `BeamIOSourceRel`.
`int`	`numSupported()`	This is primarily used by the cost based optimization to determine the benefit of performing predicate push-down for an IOSourceRel.

- Method Detail
  - getNotSupported
```
java.util.List<org.apache.beam.vendor.calcite.v1_40_0.org.apache.calcite.rex.RexNode> getNotSupported()
```
    Identify parts of a predicate that are not supported by the IO push-down capabilities to be preserved in a Calc following BeamIOSourceRel.
    
    Returns:
    
    List<RexNode> unsupported by the IO API. Should be empty when an entire condition is supported, or an unchanged List<RexNode> when predicate push-down is not supported at all.
  - numSupported
```
int numSupported()
```
    This is primarily used by the cost based optimization to determine the benefit of performing predicate push-down for an IOSourceRel.
    
    Returns:
    
    number of supported filters.
  - expressionsInFilter
```
static int expressionsInFilter(java.util.List<org.apache.beam.vendor.calcite.v1_40_0.org.apache.calcite.rex.RexNode> filterNodes)
```
    Count a number of RexNodes involved in all supported filters.
    
    Parameters:
    
    filterNodes - List<RexNode> supported filters.
    
    Returns:
    
    number of expressions involved in all supported filters.
