Field Details

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:

3.0

Method Details

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 the AST.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 a WhileStatement. To get something that will compile, be sure to embed the VariableDeclarationStatement inside a Block.

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
