Method Detail

doForward

protected T doForward(java.lang.String value)

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<java.lang.String,T extends java.lang.Enum<T>>

Parameters:

value - the instance to convert; will never be null

Returns:

the converted instance; must not be null

doBackward

protected java.lang.String doBackward(T enumValue)

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<java.lang.String,T extends java.lang.Enum<T>>

Parameters:

enumValue - the instance to convert; will never be null

Returns:

the converted instance; must not be null

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<java.lang.String,T extends java.lang.Enum<T>>

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
