EXPRESSION_PROPERTY
public static final ChildPropertyDescriptor EXPRESSION_PROPERTY
The "expression" structural property of this node type (child type:Expression
).- Since:
- 3.0
-
BODY_PROPERTY
public static final ChildPropertyDescriptor BODY_PROPERTY
The "body" structural property of this node type (child type:Statement
).- Since:

Method Detail
-
propertyDescriptors
public static List propertyDescriptors(int apiLevel)
Returns a list of structural property descriptors for this node type. Clients must not modify the result.- Parameters:
apiLevel
- the API level; one of theAST.JLS*
constants- Returns:
- a list of property descriptors (element type:
StructuralPropertyDescriptor
) - Since:
- 3.0
-
getExpression
public Expression getExpression()
Returns the expression of this while statement.- Returns:
- the expression node
-
setExpression
public void setExpression(Expression expression)
Sets the expression of this while statement.- Parameters:
expression
- the expression node- Throws:
IllegalArgumentException
- if:- the node belongs to a different AST
- the node already has a parent
- a cycle in would be created
-
getBody
public Statement getBody()
Returns the body of this while statement.- Returns:
- the body statement node
-
setBody
public void setBody(Statement statement)
Sets the body of this while statement.Special note: The Java language does not allow a local variable declaration to appear as the body of a while statement (they may only appear within a block). However, the AST will allow a
VariableDeclarationStatement
as the body of aWhileStatement
. To get something that will compile, be sure to embed theVariableDeclarationStatement
inside aBlock
.- Parameters:
statement
- the body statement node- Throws:
IllegalArgumentException
- if:- the node belongs to a different AST
- the node already has a parent
- a cycle in would be created
