Constructor Detail

BinaryExpression

protected BinaryExpression(CFG cfg,
                           CodeLocation location,
                           Expression left,
                           Expression right)

Builds the binary expression, happening at the given location in the program.

Parameters:

cfg - the cfg that this statement belongs to

location - the location where the expression is defined within the source file. If unknown, use null

left - the left hand-side of the expression

right - the right hand-side of the expression

Method Detail

getLeft

public final Expression getLeft()

Yields the left hand-side of the expression.

Returns:

the left hand-side of the expression

getRight

public final Expression getRight()

Yields the right hand-side of the expression.

Returns:

the right hand-side of the expression

setOffset

public final int setOffset(int offset)

Description copied from interface: Node

Sets the offset of this node to the given value, and then proceeds by setting the one of its nested nodes (if any) to subsequent values. The last offset used is returned.

Parameters:

offset - the offset to set

Returns:

the last offset used while setting the offsets of nested nodes

hashCode

public int hashCode()

Overrides:

hashCode in class Expression

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class Expression

accept

public final <V> boolean accept(GraphVisitor<CFG,Statement,Edge,V> visitor,
                                V tool)

Description copied from interface: Node

Accepts the given GraphVisitor. Implementors of this method are responsible for invoking GraphVisitor.visit(Object, Graph, Node) on this node after Node.accept(GraphVisitor, Object) has been invoked on all nested nodes, if any. The visiting should stop at the first of such calls that return false.

Type Parameters:

V - the type of auxiliary tool that visitor can use

Parameters:

visitor - the visitor that is visiting the Graph containing this node

tool - the auxiliary tool that visitor can use

Returns:

whether or not the visiting should stop when this call returns, as decided by the visitor itself
