Class MethodCallState

java.lang.Object

spoon.refactoring.MethodCallState

public class MethodCallState
extends java.lang.Object

This class is for the call state of a method. A method can be called by fields in a type e.g. class or by methods. Both cases are handled in this class. For checking calls by fields use methods using CtType, for fields use the methods using CtExecutable. A method is never called if both collections are empty.

Constructor Detail

MethodCallState

public MethodCallState(CtExecutable<?> method)

Parameters:

method - for saving it's call state.

Method Detail

add

public void add(CtExecutable<?> method)

Adds a CtExecutable to the methods invoking this method. Adding the same method again doesn't change the state.

Parameters:

method - invoking the method.

See Also:

Collection.add(java.lang.Object)

add

public void add(CtType<?> type)

Adds a CtType to the fields invoking this method. Adding the same CtType again doesn't change the state.

Parameters:

type - invoking the method with an initializer.

See Also:

Collection.add(java.lang.Object)

getMethod

public CtExecutable<?> getMethod()

Getter for the method, without saved call state. Returns the CtExecutable and not a copy.

Returns:

method without saved call state.

getCallerFields

public java.util.Collection<CtType<?>> getCallerFields()

Returns a collection containing all types invoking the method with a field. Even if a CtType invokes multiple times with different fields the method, the type is only present once. Returns the collection and not a copy. Changes to collection are directly backed in the state.

Returns:

Collection containing all types invoking the method with a field.

getCallerMethods

public java.util.Collection<CtExecutable<?>> getCallerMethods()

Returns a collection containing all CtExecutable invoking the method. Even if a CtExecutable invokes multiple times the method, the CtExecutable is only present once. Returns the collection and not a copy. Changes to collection are directly backed in the state.

Returns:

Collection containing all CtExecutable invoking the method.

checkCallState

public boolean checkCallState()

Checks the call state for the method.

Returns:

True if the method has no known call, false otherwise.
