Parameters:

shape - Shape to get name for.

Returns:

Default name.

getDefaultTraitName

public static String getDefaultTraitName(Shape shape)

symbol - Symbol to check.

Returns:

Returns true if the symbol maps to a Java String.

isJavaStringList

public static boolean isJavaStringList(Shape shape,
 SymbolProvider symbolProvider)

Checks if a symbol maps to a Java List<String>.

Parameters:

shape - shape to check if it resolves to a list of java strings

symbolProvider - symbol provider to use for checking member type

Returns:

Returns true if the symbol maps to a Java String List.

mapNamespace

public static String mapNamespace(String rootSmithyNamespace,
 String shapeNamespace,
 String packageNamespace)
