Struct Class 

pub struct Class { /* private fields */ }

A complete, decoded Java class file.

This type owns the parsed class-file data. Its member and constant-pool accessors return borrowed views, so no additional model allocation is required while inspecting a class.

Implementations

impl Class

pub fn version(&self) -> ClassVersion

Returns the class-file version recorded in the header.

pub fn access_flags(&self) -> u16

Returns the raw class access-flag bitset.

Interpret the bits in the context of the Java Virtual Machine Specification’s ClassFile access flags.

pub fn name(&self) -> &str

Returns this class’s internal JVM name.

Internal names use slash-separated package segments and are not normalized by FerroBabe.

pub fn super_name(&self) -> Option<&str>

Returns the direct superclass internal name, if the class has one.

None represents the java/lang/Object root class.

pub fn source_file(&self) -> Option<&str>

Returns the SourceFile attribute value when present.

pub fn interfaces(&self) -> impl ExactSizeIterator<Item = &str>

Iterates over direct interface internal names in class-file order.

pub fn fields(&self) -> impl ExactSizeIterator<Item = Field<'_>>

Iterates over fields in class-file order.

pub fn methods(&self) -> impl ExactSizeIterator<Item = Method<'_>>

Iterates over methods in class-file order.

Each returned method can borrow the class constant pool to resolve exception handler names.

pub fn constants( &self, ) -> impl ExactSizeIterator<Item = (ConstantPoolIndex, ConstantRef<'_>)>

Iterates over every constant-pool slot, including unusable reserved slots.

The returned index is the original one-based class-file index. Slot zero is included only when supplied by the underlying model and is reported as ConstantRef::Unusable.

pub fn constant(&self, index: ConstantPoolIndex) -> Option<ConstantRef<'_>>

Returns the constant-pool entry at index.

Returns None when index is outside the decoded constant pool.

Trait Implementations

impl Clone for Class

fn clone(&self) -> Class

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Class

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
