Class QualifiedType


java.lang.Object

org.eclipse.jdt.core.dom.Type
          
org.eclipse.jdt.core.dom.QualifiedType

public class QualifiedType
extends Type
extends Type

Type node for a qualified type (added in JLS3 API).

 QualifiedType:
    Type . SimpleName

Not all node arragements will represent legal Java constructs. In particular, it is nonsense if the type is an array type or primitive type. The normal use is when the type is a simple or parameterized type.

A type like "A.B" can be represented either of two ways:

QualifiedType(SimpleType(SimpleName("A")),SimpleName("B"))
SimpleType(QualifiedName(SimpleName("A"),SimpleName("B")))

The first form is preferred when "A" is known to be a type. However, a parser cannot always determine this. Clients should be prepared to handle either rather than make assumptions. (Note also that the first form became possible as of JLS3; only the second form existed in JLS2 API.)

Since:: 3.1
Restriction:: This class is not intended to be instantiated by clients.

Parameters:: apiLevel - the API level; one of the AST.JLS* constants
Returns:: a list of property descriptors (element type: StructuralPropertyDescriptor)

getQualifier

public 
Type getQualifier()

Returns the qualifier of this qualified type.

Returns:: the qualifier of this qualified type

setQualifier

public void setQualifier(
Type type)

Sets the qualifier of this qualified type to the given type.

Parameters:

type - the new qualifier of this qualified type

Throws:


IllegalArgumentException

- if:

the node belongs to a different AST
the node already has a parent

getName

public 
SimpleName getName()

Returns the name part of this qualified type.

Returns:: the name being qualified

setName

public void setName(
SimpleName name)

Sets the name part of this qualified type to the given simple name.
