EnumBuster

public EnumBuster(Class<E> clazz,
                  Class... switchUsers)

Construct an EnumBuster for the given enum class and keep the switch statements of the classes specified in switchUsers in sync with the enum values.

方法详细资料

make

public E make(String value)

Make a new enum instance, without adding it to the values array and using the default ordinal of 0.

make

public E make(String value,
              int ordinal)

Make a new enum instance with the given ordinal.

make

public E make(String value,
              int ordinal,
              Class[] additionalTypes,
              Object[] additional)

Make a new enum instance with the given value, ordinal and additional parameters. The additionalTypes is used to match the constructor accurately.

addByValue

public void addByValue(E e)

This method adds the given enum into the array inside the enum class. If the enum already contains that particular value, then the value is overwritten with our enum. Otherwise it is added at the end of the array.

In addition, if there is a constant field in the enum class pointing to an enum with our value, then we replace that with our enum instance.

The ordinal is either set to the existing position or to the last value.

Warning: This should probably never be called, since it can cause permanent changes to the enum values. Use only in extreme conditions.

参数:

e - the enum to add

deleteByValue

public boolean deleteByValue(E e)

We delete the enum from the values array and set the constant pointer to null.

参数:

e - the enum to delete from the type.

返回:

true if the enum was found and deleted; false otherwise

restore

public void restore()

Undo the state right back to the beginning when the EnumBuster was created.

undo

public boolean undo()

Undo the previous operation.

registerSwitchClass

public void registerSwitchClass(Class[] switchUsers)
