All Implemented Interfaces:

BiFunction<String,Object,Script>, Translator.ScriptTranslator.TypeTranslator

public class AnonymizingTypeTranslator
extends GroovyTranslator.DefaultTypeTranslator

This Translator will translate Bytecode into a representation that has been stripped of any user data (anonymized). A default anonymizer is provided, but can be replaced with a custom anonymizer as needed. The default anonymizer replaces any String, Numeric, Date, Timestamp, or UUID with a type-based token. Identical values will receive the same token (e.g. if "foo" is assigned "string0" then all occurrences of "foo" will be replaced with "string0").

Method Detail

getSyntax

protected String getSyntax(String o)

Description copied from class: Translator.ScriptTranslator.AbstractTypeTranslator

Take the string argument and convert it to a string representation in the target language (i.e. escape, enclose in appropriate quotes, etc.)

Overrides:

getSyntax in class GroovyTranslator.DefaultTypeTranslator

getSyntax

protected String getSyntax(Date o)

Description copied from class: Translator.ScriptTranslator.AbstractTypeTranslator

Take the Date argument and convert it to a string representation in the target language.

Overrides:

getSyntax in class GroovyTranslator.DefaultTypeTranslator

getSyntax

protected String getSyntax(Timestamp o)

Description copied from class: Translator.ScriptTranslator.AbstractTypeTranslator

Take the Timestamp argument and convert it to a string representation in the target language.

Overrides:

getSyntax in class GroovyTranslator.DefaultTypeTranslator

getSyntax

protected String getSyntax(UUID o)

Description copied from class: Translator.ScriptTranslator.AbstractTypeTranslator

Take the UUID argument and convert it to a string representation in the target language.

Overrides:

getSyntax in class GroovyTranslator.DefaultTypeTranslator

getSyntax

protected String getSyntax(Number o)

Description copied from class: Translator.ScriptTranslator.AbstractTypeTranslator

Take the numeric argument and convert it to a string representation in the target language. Languages that can discern differences in types of numbers will wish to further check the type of the Number instance itself (i.e. Double, Integer, etc.)

Overrides:

getSyntax in class GroovyTranslator.DefaultTypeTranslator

produceScript

protected Script produceScript(Class<?> o)

Description copied from class: GroovyTranslator.DefaultTypeTranslator

Gets the string representation of a class with the default implementation simply checking to see if the Class is in CoreImports or not. If it is present that means it can be referenced using the simple name otherwise it uses the canonical name.

Those building custom Translator.ScriptTranslator instances might override this if they have other classes that are not in CoreImports by default.

Overrides:

produceScript in class GroovyTranslator.DefaultTypeTranslator
