Class PlusOperation

java.lang.Object

randoop.operation.CallableOperation

randoop.operation.PlusOperation

All Implemented Interfaces:

Operation

public class PlusOperation
extends CallableOperation

PlusOperation is an Operation that represents the addition operator (+). It is used to perform addition on two numeric values or characters.

As an Operation, a call to the plus operation with two arguments is formally represented as:

    + : [t, t] -> t
 

where both operands are of type t (one of: byte, short, char, int, long, float, or double). Two operands can have different types. The output type t is determined by the Java language rules for numeric promotion.

PlusOperation

public PlusOperation()

Creates a plus operation that performs addition.

Method Detail

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

equals

public boolean equals(@Nullable java.lang.Object obj)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

execute

public ExecutionOutcome execute(java.lang.Object[] input)

Description copied from class: CallableOperation

Performs this operation using the array of input values. Returns the results of execution as an ResultOrException object and can output results to specified PrintStream.

Specified by:

execute in class CallableOperation

Parameters:

input - array containing appropriate inputs to operation

Returns:

results of executing this statement

toInt

private int toInt(java.lang.Object x)

Converts the given object to an int. If the object is a Character, it is converted to its integer value. If the object is a Number, its int value is returned.

Parameters:

x - the object to convert

Returns:

the int value of the object

toLong

private long toLong(java.lang.Object x)

Converts the given object to a long. If the object is a Character, it is converted to its long value. If the object is a Number, its long value is returned.

Parameters:

x - the object to convert

Returns:

the long value of the object

toFloat

private float toFloat(java.lang.Object x)

Converts the given object to a float. If the object is a Character, it is converted to its float value. If the object is a Number, its float value is returned.

Parameters:

x - the object to convert

Returns:

the float value of the object

toDouble

private double toDouble(java.lang.Object x)

Converts the given object to a double. If the object is a Character, it is converted to its double value. If the object is a Number, its double value is returned.

Parameters:

x - the object to convert

Returns:

the double value of the object

appendCode

public void appendCode(Type declaringType,
                       TypeTuple inputTypes,
                       Type outputType,
                       java.util.List<Variable> inputVars,
                       java.lang.StringBuilder b)

Description copied from class: CallableOperation

Produces a Java source code representation of this statement and appends it to the given StringBuilder.

Specified by:

appendCode in class CallableOperation

Parameters:

declaringType - the declaring type for this operation

inputTypes - the input types for this operation

outputType - the output type for this operation

inputVars - the list of variables that are inputs to operation

b - the StringBuilder to which code is added

toParsableString

public java.lang.String toParsableString(Type declaringType,
                                         TypeTuple inputTypes,
                                         Type outputType)

Description copied from class: CallableOperation

Returns a string representation of this Operation (not an invocation of this Operation), which can be read by the static parse method for the class in which the method is defined. For a class C implementing the Operation interface, this method should return a String s such that parsing the string returns an object equivalent to this object, i.e. C.parse(this.s).equals(this).

Specified by:

toParsableString in class CallableOperation

Parameters:

declaringType - the declaring type for this operation

inputTypes - the input types for this operation

outputType - the output type for this operation

Returns:

a string representation of this operation

getName

public java.lang.String getName()

Description copied from interface: Operation

Returns the name for the operation.

Returns:

the name for this operation
