Constructors

GraphCopier

()

Creates a new instance of an GraphCopier with the default settings.

ParametersOptions Overload

options - Object
A map of options to pass to the method.

clone - CloneTypes: The types of items that should be cloned for the copy operation. This option sets the clone property on the created object.
referentialIdentityTypes - CloneTypes: The types of objects where the referential identity should be kept across clipboard operations. This option sets the referentialIdentityTypes property on the created object.
copyGrouping - boolean: A property that determines whether grouping information should be copied to target graphs. This option sets the copyGrouping property on the created object.
copyFoldingStates - boolean: A property that determines whether additional folding states. This option sets the copyFoldingStates property on the created object.

Properties

clone

: CloneTypes

Gets or sets the types of items that should be cloned for the copy operation.

Remarks

By default everything but tags are cloned.

copyFoldingStates

: boolean

Gets or sets a property that determines whether additional folding states.

Remarks

Should be copied to target graphs.

If the source and target graphs have an instance of FoldingManager in their lookup, the additional folding state of the nodes and edges will be copied. The default is true.

copyGrouping

: boolean

Gets or sets a property that determines whether grouping information should be copied to target graphs.

Remarks

With this property set to false the GraphCopier can be used to flatten a grouped graph, i.e. remove the grouping information.

The default is true.

referentialIdentityTypes

: CloneTypes

Gets or sets the types of objects where the referential identity should be kept across clipboard operations.

Remarks

For each of the types that are set via this property, this implementation will use a caching copy mechanism as follows: If there has already been an instance copied via this clipboard (getCopy), that instance will instead be returned, otherwise, this implementation will clone the original instance (depending on the setting of clone) and cache the copy until after the operation the cache is cleared. This feature is implemented directly by the various CopyXXX methods.

Let's say nodes n1 and n2 share the same style instance s1. Then its copies share the same style instance s2 which is, however, another reference than the original s1.

By default this is enabled for all types.
