Method Details

checkReadyToUse

public org.faktorips.runtime.MessageList checkReadyToUse()

isVoid

public boolean isVoid()

Description copied from interface: Datatype

Returns true if this is the Datatype Void, otherwise false.

Specified by:

isVoid in interface Datatype

isEnum

public boolean isEnum()

Description copied from interface: Datatype

Returns true if this value datatype is an enum datatype. In this case the instance can be cast to EnumDatatype. Returns false otherwise.

Specified by:

isEnum in interface Datatype

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object

matchDatatype

public boolean matchDatatype(Datatype datatype)

Returns true if the dataType is instance of AnyDatatype otherwise it call equals(Object).

toString

public String toString()

Returns the type's name.

Overrides:

toString in class Object

compareTo

public int compareTo(Datatype o)

Compares the two type's alphabetically by their name.

Specified by:

compareTo in interface Comparable<Datatype>

hasNullObject

public boolean hasNullObject()

Description copied from interface: Datatype

Returns true if the datatype has a special instance representing null, otherwise false. The design pattern is called the null-object pattern.

Specified by:

hasNullObject in interface Datatype
