Struct ConstantPool 

pub struct ConstantPool { /* private fields */ }

An index-preserving constant pool whose slots()[index] is the physical JVM slot.

Implementations

impl ConstantPool

pub fn decode( reader: &mut ByteReader<'_>, major_version: u16, ) -> Result<Self, ConstantPoolError>

Decode the constant_pool_count and all following entries for major_version.

pub fn slots(&self) -> &[ConstantSlot]

Borrow every physical slot. Index zero and two-slot holes remain explicit.

pub fn entry( &self, source_index: u16, target_index: u16, ) -> Result<&Constant, ConstantPoolError>

Return a usable entry or a typed located target error.

pub fn validate(&self, major_version: u16) -> Result<(), ConstantPoolError>

Validate layout, version bounds, reference indices, and target categories.

pub fn encode( &self, writer: &mut ByteWriter, major_version: u16, ) -> Result<(), ConstantPoolError>

Encode the count and entries after revalidating the pool.
