final case class ByteString(bytes: Array[Byte]) extends Val

A collection of bytes.

A collection of bytes.

Unlike arrays, byte strings are implicitly null-terminated. Hence, they correspond to C-string literals. For example, ByteString(Array(97)) will be compiled to c"a\0".

A reference to java.lang.Class[_] of given symbol name.

A reference to java.lang.Class[_] of given symbol name.

Instances are emitted as global variables during code feneration. They are used to deduplicate Class instances. There should be only 1 instance per type.

Note that, althrough they are currently emitted as global variables, instances of this type could be constants. However, when we added multithreading and object monitors, we needed to edit one of its fields (specifically, lockWord), which contains an ObjectMonitor or a bit set of lock word.

Note that this class does not behave like a literal constant, which are represented by ByteString, Zero, Int, etc. Instead, it represents a pointer to some constant value.
