Package-level declarations

Types

AllowList

class AllowList : SandBox

CompilationFailed

class CompilationFailed(val errors: List<FeatherException>) : Exception

CompilerConfiguration

class CompilerConfiguration : Cloneable

DenyAll

class DenyAll : SandBox

A Sandbox which denys access to all classes. Feather is intended to be "safe", so the default sandbox is DenyAll, and therefore if the FeatherCompiler is incorrectly initialised with an appropriate Sandbox, then safety wins (and the script will fail).

FeatherClassLoader

class FeatherClassLoader(val classes: Map<String, ByteArray>, parent: ClassLoader) : ClassLoader

The simplest way to take the results of FeatherCompile, and wrap it in a ClassLoader.

FeatherCompiler

class FeatherCompiler(val configuration: CompilerConfiguration)

FeatherException

class FeatherException(val pos: FeatherPosition, message: String) : Exception

FeatherPosition

data class FeatherPosition(val source: String?, val line: Int, val column: Int, val debug: Boolean)

Identifies a position within a piece of source code, most commonly to indicate the position of an error. See FeatherException. Note that line and column are zero based (i.e. the first character is line 0, column 0). The toString method adds one to the line and column to make it more human readable.

FileScript

class FileScript(val file: File) : Script

LibraryClassLoader

class LibraryClassLoader(parent: ClassLoader) : ClassLoader

NullType

class NullType : Type

The Type of a null literal. Note, Java does not have such a type, so we have to define our own. We could NOT use Object as the type, because for example we want to assign a null value to String variable. So whatever type "null" is, it must be auto-castable to a String (and Object is not auto-castable to a String).

RealType

enum RealType : Enum<RealType>

SandBox

interface SandBox : Cloneable

Script

interface Script

If you want to compile code from a mixture of File and String, then wrap each in FileScript / StringScript, and call FeatherCompiler.compile with the list/array of Script.

StaticImportDetails

class StaticImportDetails(val klass: Class<*>, val aliasName: String, val realName: String)

StringScript

class StringScript(val name: String, val string: String) : Script
