Method Details

getElementLabel

public String getElementLabel()

The elementLabel defines the name to be used for a single object within the collection.

For example: "Address" may be the name of one object within the "Addresses" collection.

Specified by:

getElementLabel in interface DataObjectCollection

setElementLabel

public void setElementLabel(String elementLabel)

Sets name used for single object within collection.

Parameters:

elementLabel - single object name

getMinItems

public Long getMinItems()

Description copied from interface: DataObjectCollection

Gets the minimum number of items which may be in the collection.

This is an optional attribute and may not be set by the metadata provider.

Specified by:

getMinItems in interface DataObjectCollection

Returns:

The minimum number of items which must be in this collection or null if unset.

setMinItemsInCollection

public void setMinItemsInCollection(Long minOccurs)

Sets minimum items in collection.

Parameters:

minOccurs - minimum items in collection.

getMaxItems

public Long getMaxItems()

The maximum number of items which may be in the collection.

This is an optional attribute and may not be set by the metadata provider.

Specified by:

getMaxItems in interface DataObjectCollection

Returns:

The maximum number of items which may be in this collection or null if unset.

setMaxItemsInCollection

public void setMaxItemsInCollection(Long maxOccurs)

Sets maximum items in collection.

Parameters:

maxOccurs - maximum items in collection.

getDefaultOrdering

public List<DataObjectCollectionSortAttribute> getDefaultOrdering()

Gets the default ordering of a collection.

The default ordering of collection items as specified by the metadata provider.

Specified by:

getDefaultOrdering in interface DataObjectCollection

Returns:

The list of fields in order by which to sort, or an empty list if none specified.

setDefaultCollectionOrderingAttributeNames

public void setDefaultCollectionOrderingAttributeNames(List<DataObjectCollectionSortAttribute> defaultCollectionOrdering)

Sets attribute that the default order of the collection.

Parameters:

defaultCollectionOrdering - attribute name

isIndirectCollection

public boolean isIndirectCollection()

Determines whether a linked objected is used.

Whether the referenced collection uses a linking object in the underlying implementation. (In case that is somehow important to using code.).

Specified by:

isIndirectCollection in interface DataObjectCollection

Returns:

whether a linked object is used

setIndirectCollection

public void setIndirectCollection(boolean indirectCollection)

Sets whether linked item is used.

Parameters:

indirectCollection - whether link item used.

getEmbeddedCollection

public DataObjectCollection getEmbeddedCollection()

Gets the embedded collection.

Returns:

the embedded collection, if it exists.

setEmbeddedCollection

public void setEmbeddedCollection(DataObjectCollection embeddedCollection)
