Module dev.civl.abc

Package dev.civl.abc.ast.node.IF.expression

Interface OperatorNode

All Superinterfaces:

ASTNode, ExpressionNode, ForLoopInitializerNode, InitializerNode, SizeableNode

public interface OperatorNode
extends ExpressionNode

A node that represents an expression built using an operator.

The most common type of expression is an expression that involves an operator and some number of operands. The operands are the children of this AST node.

Method Details

getOperator

OperatorNode.Operator getOperator()

Returns the operator of this expression.

Returns:

the operator

setOperator

void setOperator(OperatorNode.Operator operator)

Sets the operator of this expression.

Parameters:

operator - the operator

getNumberOfArguments

int getNumberOfArguments()

Returns the number of arguments (operands) in this operator expression.

Returns:

the number of arguments

getArgument

ExpressionNode getArgument(int index)

Returns the index-th argument, indexed from 0.

Returns:

the index-th argument (operand) of this expression

setArgument

void setArgument(int index,
 ExpressionNode value)

Sets the index-th argument of this expression to be the given expression

Parameters:

index - nonnegative integer in appropriate range for the operator

value - expression to be made the operand in that index

copy

OperatorNode copy()

Description copied from interface: ASTNode

Returns a deep copy of this AST node. The node and all of its descendants will be cloned. The cloning does not copy analysis or attribute information.
