Enum Constant Detail

LEVEL_ORDER

public static final PlanNode.Traversal LEVEL_ORDER

Traverse all of the children before traversing the plan nodes under the children.

PRE_ORDER

public static final PlanNode.Traversal PRE_ORDER

Traverse the plan nodes by visiting the parent before the children. This means traversing a child (and everything below the child) before moving to the next child.

POST_ORDER

public static final PlanNode.Traversal POST_ORDER

Traverse the plan nodes by visiting the children before visiting the parent.

Method Detail

values

public static PlanNode.Traversal[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (PlanNode.Traversal c : PlanNode.Traversal.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static PlanNode.Traversal valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
