Method Detail

generateMapOperation

public static java.lang.String generateMapOperation(PsiVariable variable,
                                                    PsiType outType,
                                                    PsiElement mapper)

getShortcutMappingMethod

public static java.lang.String getShortcutMappingMethod(PsiVariable variable,
                                                        PsiType outType,
                                                        PsiElement mapper)

Returns the shortcut mapping method name

Parameters:

variable - mapper input variable

outType - output type of the mapper

mapper - mapper code

Returns:

shortcut mapping name ("boxed", "asLongStream", "asDoubleStream") if applicable, empty string if it's ditto mapping (no mapping is necessary at all) and null if no shortcut is applicable for given mapper

getMapOperationName

public static java.lang.String getMapOperationName(PsiType inType,
                                                   PsiType outType)

Returns name of the Stream API mapping operation which maps from inType to outType (assuming both types are supported by Stream API)

Parameters:

inType - input stream element type

outType - output stream element type

Returns:

a name of the mapping operation like "map" or "mapToLong".

getFlatMapOperationName

public static java.lang.String getFlatMapOperationName(PsiType inType,
                                                       PsiType outType)
