All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`List<List<List<Writable>>>`	`applyToSequence(List<List<Writable>> sequence)`	Apply the windowing function to the given sequence

- Method Detail
  - applyToSequence
```
List<List<List<Writable>>> applyToSequence(List<List<Writable>> sequence)
```
    Apply the windowing function to the given sequence
    
    Parameters:
    
    sequence - the input sequence
    
    Returns:
    
    the sequence with the window function applied
  - setInputSchema
```
void setInputSchema(Schema schema)
```
    Parameters:
    
    schema -
  - getInputSchema
```
Schema getInputSchema()
```
    Returns:
  - transform
```
Schema transform(Schema inputSchema)
```
    Get the output schema, given the input schema. Typically the output schema is the same as the input schema, but not necessarily (for example, if the window function adds columns for the window start/end times)
    
    Parameters:
    
    inputSchema - Schema of the input data
    
    Returns:
    
    Schema of the output windows
