Method Detail

getDataValue

public Object getDataValue(String component_id,
                           Object datum,
                           com.ptc.core.components.descriptor.ModelContext mc)
                    throws WTException

Will retrieve a value from a binary link using the reference object as the source. This method assumes the setModelData() method has been called to initialize the data.

Supported API: true

Parameters:

component_id - One of the supported component_ids

datum - The object to use as the reference

mc - The current model context

Throws:

WTException

getLabel

public String getLabel(String component_id,
                       com.ptc.core.components.descriptor.ModelContext mc)

Parameters:

component_id - The component ID to search the resource bundle for.

mc - The current model context.

Returns:

the label for the column.

Throws:

WTException

Method to set the Model Data. This method will try and deterministically Build up a map of the attribute values such that they can be reused for additional attributes off the binary link.

Supported API: true

Overrides:

setModelData in class com.ptc.core.components.factory.AbstractDataUtility

Parameters:

component_id - The component id of the column/attribute

objects - The objects to retrieve the data for.

mc - The model context.

Throws:

WTException
