Enum Constant Detail

PRE_ORDER

public static final TraversalStrategy PRE_ORDER

When this strategy is selected, the processor will traverse the parent elements before the children. This implies that if the processor adds new elements to a given model sub-tree, these new elements will be processed too. This strategy can easily lead to complex processing behavior, so it is to be used with care.

POST_ORDER

public static final TraversalStrategy POST_ORDER

When this strategy is selected, the processor will traverse the child elements before the parents. This implies that child elements that are removed by a processor will still be processed before they are removed.

Method Detail

values

public static TraversalStrategy[] 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 (TraversalStrategy c : TraversalStrategy.values())
    System.out.println(c);

Returns:

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

valueOf

public static TraversalStrategy 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
