UnaryExpression

UnaryExpression(ExpressionType nodeType,
 Expression operand,
 Type type,
 MethodInfo method)

Method Details

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 this Expression represents.

Overrides:

getType in class Expression

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 this Expression.

Overrides:

getNodeType in class Expression

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 into ExpressionVisitor.visitBinary().

Overrides:

accept in class Expression

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 returns true, reduce() can be called to produce the reduced form.

Overrides:

canReduce in class Expression

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. If canReduce() returns true, this should return a valid expression. This method is allowed to return another node which itself must be reduced.

Overrides:

reduce in class Expression

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)
