Enum Constant Detail

NOOP

public static final CompositeNodeDataWithSchema.ChildReusePolicy NOOP

Do not consider any existing nodes at all, just perform a straight append. Multiple occurrences of a child will result in multiple children being emitted. This is almost certainly the wrong policy unless the caller prevents such a situation from arising via some different mechanism.

REJECT

public static final CompositeNodeDataWithSchema.ChildReusePolicy REJECT

Do not allow duplicate definition of a child node. This would typically be used when a child cannot be encountered multiple times, but the caller does not make any provision to detect such a conflict. If a child node would end up being defined a second time, DuplicateChildNodeRejectedException is reported.

REUSE

public static final CompositeNodeDataWithSchema.ChildReusePolicy REUSE

Reuse previously-defined child node. This is most appropriate when a child may be visited multiple times and the intent is to append content of each visit. A typical usage is list elements with RFC7950 XML encoding, where there is no encapsulating element and hence list entries may be interleaved with other children.

Method Detail

values

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

Returns:

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

valueOf

public static CompositeNodeDataWithSchema.ChildReusePolicy 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
