Method Detail

fromFragments

public static BulkData fromFragments(Fragments bulkDataFragments)

Returns a BulkData instance combining all BulkData instances in bulkDataFragments.

Parameters:

bulkDataFragments - Fragments instance with BulkData instances referencing individual fragments

Returns:

a BulkData instance combining all BulkData instances in bulkDataFragments.

Throws:

ClassCastException - if bulkDataFragments contains byte[]

IllegalArgumentException - if bulkDataFragments contains URIs referencing different Resources or without Query Parameter length.

hasFragments

public boolean hasFragments()

Returns true, if the URI of this BulkData instance specifies offset and length of individual data fragments by Query Parameters offsets and lengths and therefore can be converted by toFragments(java.lang.String, int, org.dcm4che3.data.VR) to a Fragments instance containing BulkData instances referencing individual fragments.

Returns:

true if this BulkData instance can be converted to a Fragments instance by toFragments(java.lang.String, int, org.dcm4che3.data.VR)

toFragments

public Fragments toFragments(String privateCreator,
                             int tag,
                             VR vr)

Returns a Fragments instance with containing BulkData instances referencing individual fragments, referenced by this BulkData instances.

Parameters:

privateCreator -

tag -

vr -

Returns:

Fragments instance with containing BulkData instances referencing individual fragments, referenced by this BulkData instances

Throws:

UnsupportedOperationException, - if the URI BulkData instance does not specify offset and length of individual data fragments by Query Parameters offsets and lengths
