Fields
Modifier and Type	Field and Description
`static HashPartitioningFunction`	`INSTANCE` The single instance of this class

All Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`PartitioningFunction.Evaluator`	`getEvaluator(PartitioningFunctionContext ctx)` Create an Evaluator bound to the specified context.
`boolean`	`isEquivalentPartitioning(PartitioningFunction other)` Returns true iff, given a single row of input, this function is guaranteed to produce the same partitioning as the other function.
`boolean`	`isFunctionOfInput()` Returns true iff, given two identical rows of input, this function will return the same value.
`PartitioningFunction`	`remapFieldReferences(Map<String,String> oldToNewMapping)` Creates a new function, equivalent to the given function, but with all field references renamed according to the given mapping.
`void`	`validateForType(RecordTokenType type)` Performs validation of the specified input type

Specified by:: isEquivalentPartitioning in interface PartitioningFunction
Parameters:: other - the other function
Returns:: whether this function produces the same results as the other function.

isFunctionOfInput
```
public boolean isFunctionOfInput()
```
Description copied from interface: PartitioningFunction

Returns true iff, given two identical rows of input, this function will return the same value. A return of true thus implies :
the function is deterministic
the function is stateless (not sensitive to previous values read or to input ordering)
