public class VariableDeclarationExpression

extends Expression

Local variable declaration expression AST node type.

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 is used (only) as the initializer of a ForStatement.

 VariableDeclarationExpression:
    { Modifier } Type VariableDeclarationFragment
         { , VariableDeclarationFragment } 
 

Since:

2.0

Method Detail

getNodeType

public int getNodeType()

Description copied from class: ASTNode

Returns an integer value identifying the type of this concrete AST node. The values are small positive integers, suitable for use in switch statements.

For each concrete node type there is a unique node type constant (name and value). The unique node type constant for a concrete node type such as CastExpression is ASTNode.CAST_EXPRESSION.

Specified by:

getNodeType in class ASTNode

Returns:

one of the node type constants

subtreeMatch

public boolean subtreeMatch(ASTMatcher matcher,
                            Object other)

Description copied from class: ASTNode

Returns whether the subtree rooted at the given node matches the given other object as decided by the given matcher.

Specified by:

subtreeMatch in class ASTNode

Parameters:

matcher - the matcher

other - the other object, or null

Returns:

true if the subtree matches, or false if they do not match

getModifiers

public int getModifiers()

Returns the modifiers explicitly specified on this declaration.

Note that the final modifier is the only meaningful modifier for local variable declarations.

Returns:

the bit-wise or of Modifier constants

See Also:

Modifier

setModifiers

public void setModifiers(int modifiers)

Sets the modifiers explicitly specified on this declaration.

Note that the final modifier is the only meaningful modifier for local variable declarations.

Returns:

the bit-wise or of Modifier constants

Throws:

IllegalArgumentException - if the modifiers are illegal

See Also:

Modifier

getType

public Type 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.

Returns:

the base type

setType

public void setType(Type type)

Sets the base type declared in this variable declaration to the given type.

Parameters:

type - the new base type

Throws:

IllegalArgumentException - if:

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

fragments

public List 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 be VariableDeclarationFragments; attempts to add any other type of node will trigger an exception.

Returns:

the live list of variable declaration fragments in this expression (element type: VariableDeclarationFragment)
