Constructor Details

ForEachExpression

ForEachExpression(ParameterExpression variable,
 Expression sequence,
 Expression body,
 LabelTarget breakTarget,
 LabelTarget continueTarget)

Method Details

getVariable

public ParameterExpression getVariable()

getSequence

public Expression getSequence()

getBody

public Expression getBody()

getBreakTarget

public LabelTarget getBreakTarget()

getContinueTarget

public LabelTarget getContinueTarget()

getNodeType

public 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.

getType

public 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.

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.

update

public ForEachExpression update(ParameterExpression variable,
 Expression sequence,
 Expression body,
 LabelTarget breakTarget,
 LabelTarget continueTarget)

accept

protected 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.

visitChildren

protected Expression visitChildren(ExpressionVisitor visitor)

Description copied from class: Expression

Reduces the node and then calls the visitor on the reduced expression. Throws an exception if the node isn't reducible.

Overrides:

visitChildren in class Expression

Parameters:

visitor - an expression visitor

Returns:

the expression being visited, or an expression which should replace it in the tree.

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.

reduceForArray

private Expression reduceForArray()

reduceForIterable

private Expression reduceForIterable()

tryGetGenericEnumerableArgument

private Type<?> tryGetGenericEnumerableArgument()
