public BinaryProcedureBinaryFunction(BinaryProcedure<? super L,? super R> procedure)
```
    Create a new BinaryProcedureBinaryFunction.
    
    Parameters:
    procedure - to adapt as a BinaryFunction
- Method Detail
  - evaluate
```
public T evaluate(L left,
         R right)
```
    Evaluate this function.
    
    Specified by:
    
    evaluate in interface BinaryFunction<L,R,T>
    
    Parameters:
    left - the L element of the ordered pair of arguments
    right - the R element of the ordered pair of arguments
    
    Returns:
    the T result of this function for the given arguments
  - equals
```
public boolean equals(Object obj)
```
    Overrides:
    
    equals in class Object
  - hashCode
```
public int hashCode()
```
    Overrides:

public static <L,R,T> BinaryProcedureBinaryFunction<L,R,T> adapt(BinaryProcedure<? super L,? super R> procedure)
```
    Adapt the given, possibly-null, BinaryProcedure to the BinaryFunction interface. When the given BinaryProcedure is null, returns null.
    
    Type Parameters:
    L - the left argument type.
    R - the right argument type.
    T - the returned value type.
    Parameters:
    procedure - the possibly-null BinaryFunction to adapt
    
    Returns:
    a BinaryProcedureBinaryFunction wrapping the given BinaryFunction, or null if the given BinaryFunction is null
