Constructor Detail

IncrementalTypeDescriptor

public IncrementalTypeDescriptor(TypeDescriptor initialTypeDescriptor)

Method Detail

getLatestTypeDescriptor

public TypeDescriptor getLatestTypeDescriptor()

setLatestTypeDescriptor

public void setLatestTypeDescriptor(TypeDescriptor typeDescriptor)

getNewOrChangedMethods

public java.util.List<MethodMember> getNewOrChangedMethods()

Return the list of 'new or changed' methods. New or changed is characterised as: *

• methods that never used to exist but do now
• methods where name and descriptor are the same but something else has changed (see MethodMember.equals())
• method was represented as a catcher in the original, but is now 'real'

It does not include catchers.

getNewOrChangedConstructors

public java.util.List<MethodMember> getNewOrChangedConstructors()

Return the list of 'new or changed' constructors. New or changed is characterized as:

• constructors that did not exist in the original class as loaded, but do now
• constructors that did exist in the original class but have changed in some way (visibility)

getDeletedMethods

public java.util.List<MethodMember> getDeletedMethods()

mustUseExecutorForThisMethod

public boolean mustUseExecutorForThisMethod(int methodId)

hasBeenDeleted

public boolean hasBeenDeleted(int methodId)

getFromLatestByDescriptor

public MethodMember getFromLatestByDescriptor(java.lang.String nameAndDescriptor)

isBrandNewMethod

public static boolean isBrandNewMethod(MethodMember mm)

Returns:

true if the method is brand new after a reload (i.e. was never defined in the original type)

hasChanged

public static boolean hasChanged(MethodMember mm)

isCatcher

public static boolean isCatcher(MethodMember method)

isNowNonStatic

getOriginal

public TypeDescriptor getOriginal()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

toString

public java.lang.String toString(boolean compute)
