Class StringToReferenceTransformer<R extends Reference>

java.lang.Object

com.neurosys.refs.transformers.ReferencePersistTransformer<R>

com.neurosys.refs.transformers.StringToReferenceTransformer<R>

All Implemented Interfaces:

Serializable, org.apache.commons.collections.Transformer

public class StringToReferenceTransformer<R extends Reference>
extends ReferencePersistTransformer<R>

Convert a Raw String into a Reference type.
If splitter is provided it will assume the raw String to be a list of tokens and create a Reference for each String token.
Takes a Reference type and returns a Reference type or List of Reference type.

Method Detail

persistReference

protected R persistReference(R ref)

Description copied from class: ReferencePersistTransformer

Handle Persistence of the core Relation entity

Overrides:

persistReference in class ReferencePersistTransformer<R extends Reference>

createReference

protected R createReference(String name)
                     throws Exception

Throws:

Exception

transform

public Object transform(Object input)

Specified by:

transform in interface org.apache.commons.collections.Transformer

Overrides:

transform in class ReferencePersistTransformer<R extends Reference>

getType

public Class<R> getType()

The Reference type

setType

public void setType(Class<R> type)

The Reference type

getSplitter

public org.apache.commons.collections.Transformer getSplitter()

A StringToListTransformer that will ensure following:

1. Any String input that is delimited is tokenized with the tokens processed
2. The output will be a List is String

Can be null:

true

Default value:

null

setSplitter

public void setSplitter(org.apache.commons.collections.Transformer splitter)

A StringToListTransformer that will ensure following:

1. Any String input that is delimited is tokenized with the tokens processed
2. The output will be a List is String

Can be null:

true

Default value:

null

isPersist

public boolean isPersist()

If true will persist the reference graph

Default value:

true

setPersist

public void setPersist(boolean persist)

If true will persist the reference graph

Default value:

true

getSanitize

public org.apache.commons.collections.Transformer getSanitize()

The splitter is only applicable for collections, hence sanitization is a pre-process step that can be combined within this for convenience as a Lot of Reference data will need screening and sanitization before it can be entertained.

Any String level validation/sanitization will be performed by the splitter. E.g: _______ or -- or NA type data should be cleaned out to null

Can be null:

true

Default value:

null

setSanitize

public void setSanitize(org.apache.commons.collections.Transformer sanitize)

The splitter is only applicable for collections, hence sanitization is a pre-process step that can be combined within this for convenience as a Lot of Reference data will need screening and sanitization before it can be entertained.

Any String level validation/sanitization will be performed by the splitter. E.g: _______ or -- or NA type data should be cleaned out to null
