Attribute<CharacterRangeTableAttribute>, ClassFileElementpublic sealed interface CharacterRangeTableAttribute extends Attribute<CharacterRangeTableAttribute>
CharacterRangeTable attribute, which is a bidirectional mapping from ranges of positions in the source file to ranges of indices into the code array. Its entries are delivered as CharacterRanges when traversing the elements of a CodeModel, toggled by ClassFile.DebugElementsOption. The CharacterRangeTable attribute consists of an array of character range entries. The character range entries form a forest data structure: any two range entries are either disjoint, or if they overlap, then one entry must be enclosed within the other, both in code array indices and source file character positions. The character range entries may appear in any order.
This attribute only appears on Code attributes, permits multiple appearances but should only appear once in a Code attribute. It has a data dependency on labels.
This attribute cannot be sent to a CodeBuilder; its entries can be constructed with CharacterRange, resulting in at most one attribute instance in the built Code attribute.
This attribute is not predefined in the Java SE Platform. This is a JDK-specific nonstandard attribute produced by the reference implementation of the system Java compiler, defined by the jdk.compiler module.
