Field Details

pNullToAny

public static final ConverterFactory pNullToAny

Conversion from pkl.base#Null to any non-primitive type. The conversion result is always null.

pObjectToPObject

public static final ConverterFactory pObjectToPObject

Identity conversion for PObject.

pStringToEnum

public static final ConverterFactory pStringToEnum

Conversion from pkl.base#String to Java Enum type. If there is no exact match between string and enum value, some variations are tried. For example, both "house-of-cards" and "house of cards" will be successfully matched to enum value HOUSE_OF_CARDS.

pAnyToOptional

public static final ConverterFactory pAnyToOptional

Conversion from any Pkl value to Optional. Returns an empty optional for pkl.base#Null and a present optional otherwise.

pCollectionToArray

public static final ConverterFactory pCollectionToArray

Conversion from pkl.base#Collection to Java primitive or object array.

pCollectionToCollection

public static final ConverterFactory pCollectionToCollection

Conversion from pkl.base#Collection to Collection. The concrete implementation type is determined using TypeMappings.

pMapToMap

public static final ConverterFactory pMapToMap

Conversion from pkl.base#Map to Map. The concrete implementation type is determined using TypeMappings.

pObjectToDataObject

public static final ConverterFactory pObjectToDataObject

Conversion from Pkl module or object to Java data object. The conversion is performed as follows:

1. Find the Java class constructor with the highest number of parameters.
2. Correlate constructor parameters with Pkl object properties by name.
3. Convert each Pkl property value to the corresponding constructor parameter's type.
4. Invoke the constructor.

Dynamic and class based Pkl objects are equally supported. The Pkl object must contain all properties defined by the Java class constructor. Any additional Pkl object properties are ignored.

Unless the Java 8+ compiler option -parameters is set, constructor parameters must be annotated with Named or javax.inject.Named.

pObjectToMap

public static final ConverterFactory pObjectToMap

pPairToPair

public static final ConverterFactory pPairToPair

Conversion from pkl.base#Pair to Pair.
