Field Details

LEFT_OPERAND_PROPERTY

public static final ChildPropertyDescriptor LEFT_OPERAND_PROPERTY

The "leftOperand" structural property of this node type (child type: Expression).

Since:

3.0

OPERATOR_PROPERTY

public static final SimplePropertyDescriptor OPERATOR_PROPERTY

The "operator" structural property of this node type (type: InfixExpression.Operator).

Since:

3.0

RIGHT_OPERAND_PROPERTY

public static final ChildPropertyDescriptor RIGHT_OPERAND_PROPERTY

The "rightOperand" structural property of this node type (child type: Expression).

Since:

3.0

EXTENDED_OPERANDS_PROPERTY

public static final ChildListPropertyDescriptor EXTENDED_OPERANDS_PROPERTY

The "extendedOperands" structural property of this node type (element type: Expression).

Since:

3.0

Method Details

propertyDescriptors

public static List propertyDescriptors(int apiLevel)

Returns a list of structural property descriptors for this node type. Clients must not modify the result.

Parameters:

apiLevel - the API level; one of the AST.JLS* constants

Returns:

a list of property descriptors (element type: StructuralPropertyDescriptor)

Since:

3.0

getOperator

public InfixExpression.Operator getOperator()

Returns the operator of this infix expression.

Returns:

the infix operator

setOperator

public void setOperator(InfixExpression.Operator operator)

Sets the operator of this infix expression.

Parameters:

operator - the infix operator

Throws:

IllegalArgumentException - if the argument is incorrect

getLeftOperand

public Expression getLeftOperand()

Returns the left operand of this infix expression.

Returns:

the left operand node

setLeftOperand

public void setLeftOperand(Expression expression)

Sets the left operand of this infix expression.

Parameters:

expression - the left operand node

Throws:

IllegalArgumentException - if:

• the node belongs to a different AST
• the node already has a parent
• a cycle in would be created

getRightOperand

public Expression getRightOperand()

Returns the right operand of this infix expression.

Returns:

the right operand node

setRightOperand

public void setRightOperand(Expression expression)

Sets the right operand of this infix expression.

Parameters:

expression - the right operand node

Throws:

IllegalArgumentException - if:

• the node belongs to a different AST
• the node already has a parent
• a cycle in would be created

hasExtendedOperands

public boolean hasExtendedOperands()

Returns where there are any extended operands.

Returns:

true if there are one or more extended operands, and false if there are no extended operands

extendedOperands

public List extendedOperands()

Returns the live list of extended operands.

The extended operands is the preferred way of representing deeply nested expressions of the form L op R op R2 op R3... where the same operator appears between all the operands (the most common case being lengthy string concatenation expressions). Using the extended operands keeps the trees from getting too deep; this decreases the risk is running out of thread stack space at runtime when traversing such trees. ((a + b) + c) + d would be translated to: leftOperand: a rightOperand: b extendedOperands: {c, d} operator: +

Returns:

the live list of extended operands (element type: Expression)
