`@Nullable java.lang.reflect.AccessibleObject`	`getReflectionObject()`
`java.lang.Object`	`getValue()` Returns the "value" of an operation that is actually a ground term, meaning a constant of some form.
`boolean`	`isConstantField()` Predicate to indicate whether this object represents a constant field.
`boolean`	`isConstructorCall()` Predicate to indicate whether object represents a call to a constructor.
`boolean`	`isMessage()` Predicate to indicate whether object represents a method-call-like operation (either static or instance).
`boolean`	`isMethodCall()` Indicates whether this object represents a method-call operation (either static or instance).
`boolean`	`isNonreceivingValue()` Predicate to indicate whether this object represents a value of a non-receiving type (includes numbers, strings, and null).
`boolean`	`isStatic()` Predicate to indicate whether object represents a static operation on the declaring class.
`boolean`	`isUncheckedCast()` Predicate to indicate whether this object represents an unchecked cast.
`boolean`	`satisfies(ReflectionPredicate reflectionPredicate)` Checks whether reflective object contained in an `Operation` satisfies the predicate.
`abstract java.lang.String`	`toParsableString(Type declaringType, TypeTuple inputTypes, Type outputType)` 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.

public CallableOperation()
```
- Method Detail
  - isStatic
```

    true if operation corresponds to static method or field of a class, and false otherwise
  - isMessage
```
public boolean isMessage()
```
    Description copied from interface: Operation
    
    Predicate to indicate whether object represents a method-call-like operation (either static or instance). This includes field getters and setters, which are operations that access fields.
    
    Specified by:
    
    isMessage in interface Operation
    
    Returns:
    
    true if operation is method-like, and false otherwise
  - isMethodCall
```
public boolean isMethodCall()
```
    Description copied from interface: Operation
    
    Indicates whether this object represents a method-call operation (either static or instance). This excludes getters and setters.
    
    Specified by:
    
    isMethodCall in interface Operation
    
    Returns:
    
    true if this operation is a method call, and false otherwise
  - isConstructorCall
```
public boolean isConstructorCall()
```
    Description copied from interface: Operation
    
    Predicate to indicate whether object represents a call to a constructor.
    
    Specified by:
    
    isConstructorCall in interface Operation
    
    Returns:
    
    true if operation is a constructor call, and false otherwise
  - isConstantField
```
public boolean isConstantField()
```
    Description copied from interface: Operation
    
    Predicate to indicate whether this object represents a constant field.
    
    Specified by:
    
    isConstantField in interface Operation
    
    Returns:
    
    true if this operation is a constant field, and false otherwise
  - isNonreceivingValue
```
public boolean isNonreceivingValue()
```
    Description copied from interface: Operation
    
    Predicate to indicate whether this object represents a value of a non-receiving type (includes numbers, strings, and null).
    
    Specified by:
    
    isNonreceivingValue in interface Operation
    
    Returns:
    
    true if object is a non-receiving value, and false otherwise
  - isUncheckedCast
```
public boolean isUncheckedCast()
```
    Description copied from interface: Operation
    
    Predicate to indicate whether this object represents an unchecked cast.
    
    Specified by:
    
    isUncheckedCast in interface Operation
    
    Returns:
    
    true if the this object is a cast, and false otherwise
  - getValue
```
public java.lang.Object getValue()
```
    Description copied from interface: Operation
    
    Returns the "value" of an operation that is actually a ground term, meaning a constant of some form. Only null if value is null, otherwise throws an exception if there is not a reasonable meaning of value for type of operation.
    This is a hack to allow randoop.main.GenBranchDir to do mutation.
    
    Specified by:
    
    getValue in interface Operation
    
    Returns:
    
    object reference to value
  - satisfies
```
public boolean satisfies(ReflectionPredicate reflectionPredicate)
```
    Checks whether reflective object contained in an Operation satisfies the predicate. Since there is no reflective object in an CallableOperation, returns false.
    
    Specified by:
    
    satisfies in interface Operation
    
    Parameters:
    
    reflectionPredicate - ReflectionPredicate against which object to be checked
    
    Returns:
    
    false as there is no object to check
  - execute
```
public abstract ExecutionOutcome execute(java.lang.Object[] input)
```
    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.
    
    Parameters:
    
    input - array containing appropriate inputs to operation
    
    Returns:
    
    results of executing this statement
  - appendCode
```
public abstract void appendCode(Type declaringType,
                                TypeTuple inputTypes,
                                Type outputType,
                                java.util.List<Variable> inputVars,
                                java.lang.StringBuilder b)
```
    Produces a Java source code representation of this statement and appends it to the given StringBuilder.
    
    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
  - getArgumentString
```
java.lang.String getArgumentString(Variable variable)
```
    Returns the variable as a string to be used as an argument to an operation. Determines if the value of the variable can be given in short form. In the short output format, statements that assign to a primitive or string literal, like "int x = 3" are not added to a sequence; instead, the value (e.g. "3") is inserted directly added as arguments to method calls.
    
    Parameters:
    
    variable - the variable for which the argument string is constructed
    
    Returns:
    
    the argument string for the variable
  - toParsableString
```
public abstract java.lang.String toParsableString(Type declaringType,
                                                  TypeTuple inputTypes,
                                                  Type outputType)
```
    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).
    
    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
  - getReflectionObject
```
public @Nullable java.lang.reflect.AccessibleObject getReflectionObject()
```
