LEFT_OPERAND_PROPERTY
public static final
ChildPropertyDescriptor LEFT_OPERAND_PROPERTY
- The "leftOperand" structural property of this node type.
-
Since:
- 3.0
OPERATOR_PROPERTY
public static final
SimplePropertyDescriptor OPERATOR_PROPERTY
- The "operator" structural property of this node type.
-
Since:
- 3.0
RIGHT_OPERAND_PROPERTY
public static final
ChildPropertyDescriptor RIGHT_OPERAND_PROPERTY
- The "rightOperand" structural property of this node type.
-
Since:
- 3.0
EXTENDED_OPERANDS_PROPERTY
public static final
ChildListPropertyDescriptor EXTENDED_OPERANDS_PROPERTY
- The "extendedOperands" structural property of this node type.
-
Since:
- 3.0
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)
