Method Detail

doForward

protected A doForward(B b)

Description copied from class: Converter

Returns a representation of a as an instance of type B. If a cannot be converted, an unchecked exception (such as IllegalArgumentException) should be thrown.

Specified by:

doForward in class Converter<B,A>

Parameters:

b - the instance to convert; will never be null

Returns:

the converted instance; must not be null

doBackward

protected B doBackward(A a)

Description copied from class: Converter

Returns a representation of b as an instance of type A. If b cannot be converted, an unchecked exception (such as IllegalArgumentException) should be thrown.

Specified by:

doBackward in class Converter<B,A>

Parameters:

a - the instance to convert; will never be null

Returns:

the converted instance; must not be null

correctedDoForward

A correctedDoForward(B b)

Overrides:

correctedDoForward in class Converter<B,A>

correctedDoBackward

B correctedDoBackward(A a)

Overrides:

correctedDoBackward in class Converter<B,A>

reverse

public Converter<A,B> reverse()

Description copied from class: Converter

Returns the reversed view of this converter, which converts this.convert(a) back to a value roughly equivalent to a.

The returned converter is serializable if this converter is.

Note: you should not override this method. It is non-final for legacy reasons.

Overrides:

reverse in class Converter<B,A>

equals

public boolean equals(java.lang.Object object)

Description copied from class: Converter

Indicates whether another object is equal to this converter.

Most implementations will have no reason to override the behavior of Object.equals(java.lang.Object). However, an implementation may also choose to return true whenever object is a Converter that it considers interchangeable with this one. "Interchangeable" typically means that Objects.equal(this.convert(a), that.convert(a)) is true for all a of type A (and similarly for reverse). Note that a false result from this method does not imply that the converters are known not to be interchangeable.

Overrides:

equals in class Converter<B,A>

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
