com.neurosys.modules.etl.EntityResourceUploadActionTransformer<T>

com.neurosys.modules.etl.EntityUpdateResUploadActionTransformer<T>

com.neurosys.modules.etl.VelocityEntityUpdateResUploadActionTransformer<T>

All Implemented Interfaces:

org.apache.commons.collections.Transformer

public class VelocityEntityUpdateResUploadActionTransformer<T>
extends EntityUpdateResUploadActionTransformer<T>

This implementation is a velocity based template constructor. Where the path of the file remains the same except the name, which is modified based on templatePattern. The resulting change is updated or appended to the EntityUpdateResUploadActionTransformer.relatedField in the Entity.

getTemplatePattern

public String getTemplatePattern()

A pattern defined by Velocity Template Language (VTL) that uses variables.

Variable types can be entity.<name of field> or <context variable> or sequenceCode.
sequenceCode a special variable as int type, that is determined based on the last sequence if paths are already assigned to EntityUpdateResUploadActionTransformer.relatedField. It is incremented by 1. If EntityUpdateResUploadActionTransformer.relatedField is not acollectionType then this is always 1.

The extension of the path (if any) will be retained and is not part of the template.
Example: $entity.productCode-$facetMeta.name-$sequenceCode

setTemplatePattern

public void setTemplatePattern(String templatePattern)

A pattern defined by Velocity Template Language (VTL) that uses variables.

Variable types can be entity.<name of field> or <context variable> or sequenceCode.
sequenceCode a special variable as int type, that is determined based on the last sequence if paths are already assigned to EntityUpdateResUploadActionTransformer.relatedField. It is incremented by 1. If EntityUpdateResUploadActionTransformer.relatedField is not acollectionType then this is always 1.

The extension of the path (if any) will be retained and is not part of the template.
Example: $entity.productCode-$facetMeta.name-$sequenceCode
