Method Detail
-
getOperand
public final Expression getOperand()
Gets the implementing method for the unary operation.- Returns:
- an
Expression
that represents the operand of the unary operation.
-
getMethod
public final MethodInfo getMethod()
Gets the implementing method for the unary operation.- Returns:
- the
MethodInfo
that represents the implementing method.
-
getType
public final Type<?> getType()
Description copied from class:Expression
Gets the static type of the expression that thisExpression
represents.- Overrides:
getType
in classExpression
- Returns:
- the
Type
that represents the static type of the expression.
-
getNodeType
public final ExpressionType getNodeType()
Description copied from class:Expression
Returns the node type of thisExpression
.- Overrides:
getNodeType
in classExpression
- Returns:
- the
ExpressionType
that represents this expression.
-
accept
protected final Expression accept(ExpressionVisitor visitor)
Description copied from class:Expression
Dispatches to the specific visit method for this node type. For example,BinaryExpression
will call intoExpressionVisitor.visitBinary()
.- Overrides:
accept
in classExpression
- Parameters:
visitor
- the visitor to visit this node.- Returns:
- the result of visiting this node.
-
canReduce
public final boolean canReduce()
Description copied from class:Expression
Indicates that the node can be reduced to a simpler node. If this returnstrue
,reduce()
can be called to produce the reduced form.- Overrides:
canReduce
in classExpression
- Returns:
true
if the node can be reduced; otherwise,false
.
-
reduce
public final Expression reduce()
Description copied from class:Expression
Reduces this node to a simpler expression. IfcanReduce()
returnstrue
, this should return a valid expression. This method is allowed to return another node which itself must be reduced.- Overrides:
reduce
in classExpression
- Returns:
- the reduced expression.
-
reduceVariable
private Expression reduceVariable()
-
reduceMember
private Expression reduceMember()
-
isPrefix
private boolean isPrefix()
-
functionalOp
private UnaryExpression functionalOp(Expression operand)
-
update
public final UnaryExpression update(Expression operand)
