Klasse VariableDeclarationExpression
This kind of node collects together several variable declaration fragments
(VariableDeclarationFragment
) into a single expression
(Expression
), all sharing the same modifiers and base type.
This type of node can be used as the initializer of a
ForStatement
, or wrapped in an ExpressionStatement
to form the equivalent of a VariableDeclarationStatement
.

propertyDescriptors
Returns a list of structural property descriptors for this node type. Clients must not modify the result.- Parameter:

StructuralPropertyDescriptor
) - Seit:

modifiers
Returns the live ordered list of modifiers and annotations of this declaration (added in JLS3 API).Note that the final modifier is the only meaningful modifier for local variable declarations.
- Gibt zurück:
- the live list of modifiers and annotations
(element type:
IExtendedModifier
) - Löst aus:
UnsupportedOperationException
- if this operation is used in a JLS2 AST- Seit:

getModifiers
public int getModifiers()Returns the modifiers explicitly specified on this declaration.In the JLS3 API, this method is a convenience method that computes these flags from
modifiers()
.- Gibt zurück:
- the bit-wise or of
Modifier
constants - Siehe auch:

setModifiers
public void setModifiers(int modifiers) Veraltet.In the JLS3 API, this method is replaced bymodifiers()
which contains a list of aModifier
nodes.Sets the modifiers explicitly specified on this declaration (JLS2 API only).Note that the final modifier is the only meaningful modifier for local variable declarations.
- Parameter:
modifiers
- the given modifiers (bit-wise or ofModifier
constants)- Löst aus:
UnsupportedOperationException
- if this operation is used in an AST later than JLS2- Siehe auch:
-
getType
Returns the base type declared in this variable declaration.N.B. The individual child variable declaration fragments may specify additional array dimensions. So the type of the variable are not necessarily exactly this type.
- Gibt zurück:
- the base type
-
setType
Sets the base type declared in this variable declaration to the given type.- Parameter:
type
- the new base type- Löst aus:
IllegalArgumentException
- if:- the node belongs to a different AST
- the node already has a parent
-
fragments
Returns the live list of variable declaration fragments in this expression. Adding and removing nodes from this list affects this node dynamically. All nodes in this list must beVariableDeclarationFragment
s; attempts to add any other type of node will trigger an exception.- Gibt zurück:
- the live list of variable declaration fragments in this
expression (element type:
