Constructor Detail

PrimitiveExpression

public PrimitiveExpression(TestCase testCase,
                           VariableReference reference,
                           VariableReference leftOperand,
                           PrimitiveExpression.Operator operator,
                           VariableReference rightOperand)

Constructor for PrimitiveExpression.

Parameters:

testCase - a TestCase object.

reference - a VariableReference object.

leftOperand - a VariableReference object.

operator - a PrimitiveExpression.Operator object.

rightOperand - a VariableReference object.

Method Detail

changeClassLoader

public void changeClassLoader(ClassLoader loader)

Class instances are bound to a class loader - if we want to reexecute a test on a different classloader we need to be able to change the class of the reflection object

Specified by:

changeClassLoader in interface Statement

Overrides:

changeClassLoader in class AbstractStatement

Parameters:

loader - a ClassLoader object.

copy

public Statement copy(TestCase newTestCase,
                      int offset)

copy

Parameters:

newTestCase - the testcase in which this statement will be inserted

offset - a int.

Returns:

a Statement object.

execute

public Throwable execute(Scope scope,
                         PrintStream out)
                  throws InvocationTargetException,
                         IllegalArgumentException,
                         IllegalAccessException,
                         InstantiationException

This method executes the statement under the given scope. If execution of the statement is aborted abnormally (i.e. an exception is thrown.) The exception is returned. Otherwise the return value is null.

Parameters:

scope - the scope under which the statement is executed

out - a PrintStream object.

Returns:

if an exception was thrown during execution this is the exception

Throws:

InvocationTargetException - if any.

IllegalArgumentException - if any.

IllegalAccessException - if any.

InstantiationException - if any.

getAccessibleObject

public GenericAccessibleObject<?> getAccessibleObject()

Returns the accessibleObject which is used to generate this kind of statement E.g. the Field of a FieldStatement, the Method of a MethodStatement and so on MAY return NULL (for example for NullStatements)

Returns:

a AccessibleObject object.

getCode

public String getCode()

Create a string representing the statement as Java code

Specified by:

getCode in interface Statement

Overrides:

getCode in class AbstractStatement

Returns:

a String object.

getLeftOperand

public VariableReference getLeftOperand()

Getter for the field leftOperand.

Returns:

a VariableReference object.

getOperator

public PrimitiveExpression.Operator getOperator()

Getter for the field operator.

Returns:

a PrimitiveExpression.Operator object.

getRightOperand

public VariableReference getRightOperand()

Getter for the field rightOperand.

Returns:

a VariableReference object.

getUniqueVariableReferences

public List<VariableReference> getUniqueVariableReferences()

getUniqueVariableReferences

Returns:

a List object.

getVariableReferences

public Set<VariableReference> getVariableReferences()

getVariableReferences

Returns:

a Set object.

isAssignmentStatement

public boolean isAssignmentStatement()

Returns true if this statement should be handled as an AssignmentStatement. This method was added to allow the wrapping of AssignmentStatements (in which case "a instanceof AssignmentStatement" is no longer working)

Returns:

a boolean.

replace

public void replace(VariableReference oldVar,
                    VariableReference newVar)

Replace a VariableReference with another one

Parameters:

oldVar - The old variable

newVar - The new variable

same

public boolean same(Statement s)

Allows the comparing of Statements between TestCases. I.e. this is a more semantic comparison than the one done by equals. E.g. two Variable are equal if they are at the same position and they reference to objects of the same type.

Parameters:

s - a Statement object.

Returns:

a boolean.

toString

public String toString()

Overrides:

toString in class Object
