Field Detail

leftOperandNode

protected ExpressionNodeBase leftOperandNode

The expression to the left of the operator

rightOperandNode

protected ExpressionNodeBase rightOperandNode

The expression to the right of the operator

Constructor Detail

BinaryOperatorNodeBase

public BinaryOperatorNodeBase(IASToken op,
                      ExpressionNodeBase left,
                      ExpressionNodeBase right)

Constructor.

Creates a BinaryOperatorNode from an operator and both operands. If either operand is null, we will synthesize empty IdentifierNode to repair the tree.

Parameters:

op - operator token

left - first operand

right - second operand

BinaryOperatorNodeBase

protected BinaryOperatorNodeBase(BinaryOperatorNodeBase other)

Copy constructor.

Parameters:

other - The node to copy.

Method Detail

create

public static BinaryOperatorNodeBase create(IASToken operatorToken,
                            ExpressionNodeBase leftOperand,
                            ExpressionNodeBase rightOperand)

Factory method for various kinds of binary operator nodes.

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

setChildren

protected void setChildren(boolean fillInOffsets)

Description copied from class: NodeBase

If this node has custom children (names, arguments, etc), shove them into the list of children. Used during parsing.

Overrides:

setChildren in class NodeBase

fillInOffsets

protected void fillInOffsets()

Description copied from class: NodeBase

If the start and end offsets haven't been set explicitly, fill them in based on the offsets of the children. Used during parsing. If the end offset is less than any of the kids' offsets, change fLocation.fEnd to encompass kids.

Overrides:

fillInOffsets in class NodeBase

resolveType

public ITypeDefinition resolveType(ICompilerProject project)

Description copied from interface: IExpressionNode

The type of the result of this expression. This method returns the IDefinition representing the type that is the result of this expression. This can differ from the IDefinition you get from resolve(), such as when called on a FunctionCallNode: resolve() will return the IDefinition for the Function, whereas resolveType() will return the return type of the Function.

Specified by:

resolveType in interface IExpressionNode

Overrides:

resolveType in class ExpressionNodeBase

Parameters:

project - The ICompilerProject to use to do lookups.

Returns:

The ITypeDefinition of the type this expression results in.

getExpressionType

public IOperatorNode.ExpressionType getExpressionType()

Description copied from interface: IOperatorNode

Returns the type of expression that is represented by this node

Specified by:

getExpressionType in interface IOperatorNode

Returns:

the type of our expression

getLeftOperandNode

public IExpressionNode getLeftOperandNode()

Description copied from interface: IBinaryOperatorNode

Get expression to the left of the operator

Specified by:

getLeftOperandNode in interface IBinaryOperatorNode

Returns:

left expression

getRightOperandNode

public IExpressionNode getRightOperandNode()

Description copied from interface: IBinaryOperatorNode

Get expression to the right of the operator

Specified by:

getRightOperandNode in interface IBinaryOperatorNode

Returns:

right expression

setLeftOperandNode

public void setLeftOperandNode(ExpressionNodeBase leftOperandNode)

Sets the left-hand side of the expression.

Parameters:

leftOperandNode - Left-hand side expression.

setRightOperandNode

public void setRightOperandNode(ExpressionNodeBase rightOperandNode)

Sets the right side of the expression

Parameters:

rightOperandNode - ExpressionNodeBase to the right of the operator

isOperatingOnArray

public boolean isOperatingOnArray()

resolveAssignmentType

protected ITypeDefinition resolveAssignmentType(ICompilerProject project)

Utility method called by resolveType(ICompilerProject) in subclasses for assignment operators.

resolveLogicalType

protected ITypeDefinition resolveLogicalType(ICompilerProject project)

Utility method called by resolveType(ICompilerProject) in subclasses for the && and || operators.
