Decomposes an aggregate feature into its components.

Each output feature may keep a complete, unaltered copy of the source feature's attributes.

Attribute Accumulation

In some cases, a feature's non-list attributes may share the same name as attributes that are generated by the Deaggregator. For example, consider a feature with a non-list attribute length and a list attribute somelist{0}.length, somelist{0}.kind, somelist{1}.length, somelist{1}.kind,... If somelist is exploded, the feature may contain two length attributes - one from the original, non-list attribute, and one from the somelist list attribute. If the generated attributes share the same name as a feature's original, non-list attributes, but are not geometry attributes that start with fme_, they are deemed conflicted.

Use the following parameters to specify which attributes to keep on the output features, and which attribute's values to maintain in case of conflicts.

Editing Transformer Parameters

Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.

Defining Values

There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.

Dialog Options - Tables

Transformers with table-style parameters have additional tools for populating and manipulating values.
