Enclosing class:

CompilationResult

public static final class CompilationResult.JumpTable
extends CompilationResult.CodeAnnotation

Describes a table of signed offsets embedded in the code. The offsets are relative to the starting address of the table. This type of table can be generated when translating a multi-way branch based on a key value from a dense value set (e.g. the tableswitch JVM instruction). The table is indexed by the contiguous range of integers from CompilationResult.JumpTable.low to CompilationResult.JumpTable.high inclusive.
