EntityDataElement

public EntityDataElement(String name,
 String resourceId,
 String childPrefix,
 List<DataElement<?>> attributes,
 Set<DataElement.Flag> flags)

Creates a new instance.

Parameter:

name - The name of this data element

resourceId - The resource to label the data element with

childPrefix - The prefix string for child elements

attributes - The child elements that represent the entity attributes (including children)

flags - The optional flags for this data element

Methodendetails

copy

public EntityDataElement copy(DataElement.CopyMode mode,
 de.esoco.lib.property.PropertyName<?>... copyProperties)

Returns a copy of this data element that contains all or a subset of it's current state. Always copied are the name and flags. Never copied is the parent reference because upon copying typically a reference to a copied parent needs to be set. The further data the copy contains depends on the copy mode:

• DataElement.CopyMode.FULL: The copy contains all data (except the parent reference).
• DataElement.CopyMode.FLAT: like DataElement.CopyMode.FULL but without sub-ordinate data elements.
• DataElement.CopyMode.PROPERTIES: The copy contains only the properties but not the element value and attributes.
• DataElement.CopyMode.PLACEHOLDER: The copy contains only the element name to serve as a placeholder.

The copy instance is created by invoking DataElement.newInstance() which has the recommendation to overwrite the return type to the concrete subtype to prevent the need for casting by the invoking code. For the same reason it is recommended that subclasses also override this method with the concrete return type and cast the result of super.copy() to that type.

copy in Klasse DataElementList

Parameter:

mode - The copy mode

copyProperties - An optional list of properties to copy. If not provided all properties will be copied (unless the mode is DataElement.CopyMode.PLACEHOLDER)

Gibt zurück:

The copied instance

getChildResourceIdPrefix

protected String getChildResourceIdPrefix()

Overridden to return the simple name of the entity class.

Gibt zurück:

The child resource id prefix

newInstance

protected EntityDataElement newInstance()

Returns a new instance of the respective data element sub-type on which it is invoked. This is needed for GWT which doesn't support reflection. Used by DataElement.copy(CopyMode, PropertyName...) for cloning an instance. Implementations should overwrite the return type with their concrete type to prevent the need for casting by the invoking code.
