Enum RequiredChildResourceDiscardPolicy

java.lang.Object

java.lang.Enum<RequiredChildResourceDiscardPolicy>

org.jboss.as.clustering.controller.transform.RequiredChildResourceDiscardPolicy

All Implemented Interfaces:

Serializable, Comparable<RequiredChildResourceDiscardPolicy>, org.jboss.as.controller.transform.description.DynamicDiscardPolicy

public enum RequiredChildResourceDiscardPolicy
extends Enum<RequiredChildResourceDiscardPolicy>
implements org.jboss.as.controller.transform.description.DynamicDiscardPolicy

Implementation of a generic DynamicDiscardPolicy that discards child resources which have all their attribute undefined and have no children. Conditionally rejects or leaves resource for further transformation. It is to be used for required child resources that are auto-created.

Enum Constant Detail

REJECT_AND_WARN

public static final RequiredChildResourceDiscardPolicy REJECT_AND_WARN

Policy that discards if all attributes are undefined and resource has no children; rejects otherwise.

NEVER

public static final RequiredChildResourceDiscardPolicy NEVER

Policy that discards if all attributes are undefined and resource has no children; never discards otherwise (DiscardPolicy.NEVER) in order to proceed with resource transformations.

Method Detail

values

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

Returns:

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

valueOf

public static RequiredChildResourceDiscardPolicy 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

checkResource

public org.jboss.as.controller.transform.description.DiscardPolicy checkResource(org.jboss.as.controller.transform.TransformationContext context,
                                                                                 org.jboss.as.controller.PathAddress address)

Specified by:

checkResource in interface org.jboss.as.controller.transform.description.DynamicDiscardPolicy

Returns:

contextual discard policy if any resource attributes are undefined and has no children; DiscardPolicy.SILENT otherwise.
