Field Detail

variableNode

protected VariableNode variableNode

The variable that is contained within this expression

Constructor Detail

VariableExpressionNode

public VariableExpressionNode(VariableNode variableNode)

Constructor.

Parameters:

variableNode - The node representing the variable declaration.

VariableExpressionNode

protected VariableExpressionNode(VariableExpressionNode other)

Copy constructor.

Parameters:

other - The node to copy.

Method Detail

getNodeID

public ASTNodeID getNodeID()

Description copied from interface: IASNode

Get the opcode of this node

Specified by:

getNodeID in interface IASNode

Returns:

the opcode - this is one of the constants defined in ASTConstants

getChildCount

public int getChildCount()

Description copied from interface: IASNode

Get the number of children

Specified by:

getChildCount in interface IASNode

Overrides:

getChildCount in class NodeBase

Returns:

the number of children

getChild

public IASNode getChild(int i)

Description copied from interface: IASNode

Get a particular child of this node

Specified by:

getChild in interface IASNode

Overrides:

getChild in class NodeBase

Parameters:

i - the child's index

Returns:

the specified child

copy

protected VariableExpressionNode copy()

Description copied from class: ExpressionNodeBase

Copy the ExpressionNodeBase and its subtree.

Specified by:

copy in class ExpressionNodeBase

Returns:

a new ExpressionNodeBase that represents the same content as the original node

isDynamicExpression

public boolean isDynamicExpression(ICompilerProject project)

Description copied from interface: IExpressionNode

Does this expression evaluate to a dynamic value

Specified by:

isDynamicExpression in interface IExpressionNode

Overrides:

isDynamicExpression in class ExpressionNodeBase

Parameters:

project - The ICompilerProject to use to do lookups.

Returns:

true if we evaluate to something dynamic

getTargetVariable

public IVariableNode getTargetVariable()

Specified by:

getTargetVariable in interface IVariableExpressionNode

Returns:

The target's IVariableNode context.

setTargetVariable

public void setTargetVariable(VariableNode variableNode)

Sets the target variable found within this expression. Used during parsing

Parameters:

variableNode - a variable node
