Method Details

validate

public org.faktorips.runtime.MessageList validate()

getName

public String getName()

Description copied from interface: Datatype

Returns the datatype's name.

Specified by:

getName in interface Datatype

getQualifiedName

public String getQualifiedName()

Description copied from interface: Datatype

Returns the datatype's qualified name.

The qualified name identifies the datatype.

Specified by:

getQualifiedName in interface Datatype

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

isPrimitive

public boolean isPrimitive()

Description copied from interface: Datatype

Returns true if this datatype represents one of Java's primitive types.

Specified by:

isPrimitive in interface Datatype

isAbstract

public boolean isAbstract()

Description copied from interface: Datatype

Returns true if this datatype is an abstract datatype in means of the object oriented paradigm.

Specified by:

isAbstract in interface Datatype

isValueDatatype

public boolean isValueDatatype()

Description copied from interface: Datatype

Returns true if this datatype represents values.

If the method returns true, the datatype can be safely casted to ValueDatatype.

Specified by:

isValueDatatype 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

compareTo

public int compareTo(Datatype o)

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
