Fields

minor_version: u16

The minor version of the class file format.

major_version: u16

The major version of the class file format (e.g., 52 for Java 8, 61 for Java 17).

access_flags: u16

A bitmask of access flags used to denote access permissions to and properties of this class (e.g., ACC_PUBLIC, ACC_FINAL, ACC_INTERFACE).

constant_pool: Vec<CpInfo>

The raw constant pool containing heterogeneous constants (strings, integers, method references, etc.). Index 0 is reserved/unused.

this_class: u16

The index into the constant pool pointing to a CONSTANT_Class_info structure representing this class.

name: String

The internal name of the class (e.g., java/lang/String).

super_name: Option<String>

The internal name of the superclass (e.g., java/lang/String, a/b/c). Returns None if this class is java.lang.Object.

source_file: Option<String>

The name of the source file from which this class was compiled, if the SourceFile attribute was present.

interfaces: Vec<String>

A list of internal names of the direct superinterfaces of this class or interface.

interface_indices: Vec<u16>

A list of indices into the constant pool representing the direct superinterfaces.

fields: Vec<FieldNode>

The fields declared by this class or interface.

methods: Vec<MethodNode>

The methods declared by this class or interface.

attributes: Vec<AttributeInfo>

Global attributes associated with the class (e.g., SourceFile, InnerClasses, EnclosingMethod).

inner_classes: Vec<InnerClassNode>

The inner class entries associated with this class file.

This is a decoded view of the InnerClasses attribute.

outer_class: String

The internal name of the enclosing class, if known.

This value is empty when no enclosing class information is available.
