Class ClinicalTrialsAttributes

public abstract class ClinicalTrialsAttributes
extends Object

An abstract class of static methods to support removing identifying attributes and adding Clinical Trials Patient, Study and Series Modules attributes.

UID attributes are handled specially, in that they may be kept, removed or remapped. Remapping means that any UID that is not standard (e.g., not a SOP Class, etc.) will be replaced consistently with another generated UID, such that when that UID is encountered again, the same replacement value will be used. The replacement mapping persists within the invocation of the JVM until it is explciitly flushed. A different JVM invocation will replace the UIDs with different values. Therefore, multiple instances that need to be remapped consistently must be cleaned within the same invocation.

Note that this map could grow quite large and consumes resources in memory, and hence in a server application should be flushed at appropriate intervals using the appropriate method.
