Constructor Details

SwitchExpression

public SwitchExpression(Type type,
 Expression switchValue,
 Expression defaultBody,
 MethodInfo comparison,
 ReadOnlyList<SwitchCase> cases,
 SwitchOptions options)

Method Details

getSwitchValue

public final Expression getSwitchValue()

getCases

public final ReadOnlyList<SwitchCase> getCases()

getDefaultBody

public final Expression getDefaultBody()

getComparison

public final MethodInfo getComparison()

getOptions

public final SwitchOptions getOptions()

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.

update

public final SwitchExpression update(Expression switchValue,
 ReadOnlyList<SwitchCase> cases,
 Expression defaultBody,
 SwitchOptions options)

canReduce

public 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 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.

rewriteStringSwitch

private Expression rewriteStringSwitch()

rewriteEnumSwitch

private Expression rewriteEnumSwitch()
