of

public static PythonTranslator of(String traversalSource)

getTraversalSource

public String getTraversalSource()

Description copied from interface: Translator

Get the TraversalSource representation rooting this translator. For string-based translators (Translator.ScriptTranslator), this is typically a "g". For java-based translators (Translator.StepTranslator), this is typically the TraversalSource instance which the Traversal will be built from.

Specified by:

getTraversalSource in interface Translator<String,String>

Returns:

the traversal source representation

translate

public String translate(Bytecode bytecode)

Description copied from interface: Translator

Translate Bytecode into a new representation. Typically, for language translations, the translation is to a string represenging the traversal in the respective scripting language.

Specified by:

translate in interface Translator<String,String>

Parameters:

bytecode - the byte code representing traversal source and traversal manipulations.

Returns:

the translated object

getTargetLanguage

public String getTargetLanguage()

Description copied from interface: Translator

Get the language that the translator is converting the traversal byte code to.

Specified by:

getTargetLanguage in interface Translator<String,String>

Returns:

the language of the translation

toString

public String toString()

Overrides:

toString in class Object

convertToString

protected String convertToString(Object object)

convertLambdaToString

protected String convertLambdaToString(Lambda lambda)

resolveSymbol

protected String resolveSymbol(String methodName)

resolveTraversalStrategyProxy

protected String resolveTraversalStrategyProxy(TraversalStrategyProxy proxy)
