Method Detail

of

public static BinaryOperation of(java.lang.Object type)

Create a binary operation.

Parameters:

type - a OperatorType or a String representing the operator.

create

public static BinaryOperation create(java.lang.Object type,
                                     java.lang.Object left,
                                     java.lang.Object right)

Full generic binary operation creation in one call.

Less readable than the fluent API, but useful when doing meta-generation

Parameters:

type - the type of the operation (of(Object))

left - the left expression.

right - the right expression.

Returns:

a configured binary operation.

self

protected BinaryOperation self()

Specified by:

self in class GoloElement<BinaryOperation>

getType

public OperatorType getType()

left

public ExpressionStatement<?> left()

left

public BinaryOperation left(java.lang.Object expr)

Define the left expression of this operation.

This is a builder method.

Parameters:

expr - the ExpressionStatement to use as the left operand

Returns:

this operation

right

public BinaryOperation right(java.lang.Object expr)

Define the right expression of this operation.

This is a builder method.

Parameters:

expr - the ExpressionStatement to use as the right operand

Returns:

this operation

right

public ExpressionStatement<?> right()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

isMethodCall

public boolean isMethodCall()

__$$_destruct

public java.lang.Object[] __$$_destruct(int number,
                                        boolean substruct,
                                        java.lang.Object[] toSkip)

New style destructuring helper.

The destructuring must be to exactly two values. No remainer syntax is allowed.

The destructured values are the left and right expressions.

Parameters:

number - number of variable that will be affected.

substruct - whether the destructuring is complete or should contains a sub structure.

toSkip - a boolean array indicating the elements to skip.

Returns:

an array containing the values to assign.

accept

public void accept(GoloIrVisitor visitor)

Accept the visitor.

This method should only call the visitor visitXXXX method. The children of this node will be visited by the GoloElement.walk(GoloIrVisitor) method.

Specified by:

accept in class GoloElement<BinaryOperation>

children

public java.util.List<GoloElement<?>> children()

Returns a list of all the direct children of this node.

Overrides:

children in class GoloElement<BinaryOperation>

replaceElement

protected void replaceElement(GoloElement<?> original,
                              GoloElement<?> newElement)

Replace a child.

Replace original with newElement if original is a child of this node and type matches.

Specified by:

replaceElement in class GoloElement<BinaryOperation>

Parameters:

original - the original value to replace. Must be a child of this node

newElement - the element to replace with. Type must match.
