- Packages that use Constant
  Package | Description
  --- | ---
  org.apache.bcel.classfile | This package contains the classes that describe the structure of a Java class file and a class file parser.

    Methods in org.apache.bcel.classfile that return Constant
    Modifier and Type | Method and Description
    --- | ---
    `Constant` | Constant.`copy()`
    `Constant` | ConstantPool.`getConstant(int index)` Get constant from constant pool.
    `Constant` | ConstantPool.`getConstant(int index, byte tag)` Get constant from constant pool and check whether it has the expected type.
