Uses of Class org.apache.bcel.generic.ConstantPoolGen (Apache Commons BCEL 6.4.1 API)

## Uses of Class
org.apache.bcel.generic.ConstantPoolGen

- Packages that use ConstantPoolGen
  Package | Description
  --- | ---
  org.apache.bcel.generic | This package contains the "generic" part of the Byte Code Engineering Library, i.e., classes to dynamically modify class objects and byte code instructions.
  org.apache.bcel.verifier.structurals | Provides a PassVerifier class mostly used internally by JustIce, yielding a control flow graph for public use as a nice side effect.

    Methods in org.apache.bcel.generic that return ConstantPoolGen
    Modifier and Type | Method and Description
    --- | ---
    `ConstantPoolGen` | ClassGen.`getConstantPool()`

    `ConstantPoolGen` | FieldGenOrMethodGen.`getConstantPool()`
    `ConstantPoolGen` | InstructionFactory.`getConstantPool()`

    Methods in org.apache.bcel.generic with parameters of type ConstantPoolGen
    Modifier and Type | Method and Description
    --- | ---
    `void` | MethodGen.`addAnnotationsAsAttribute(ConstantPoolGen cp)`
    `int` | ConstantPoolGen.`addConstant(Constant c, ConstantPoolGen cp)` Import constant from another ConstantPool and return new index.
    `void` | MethodGen.`addParameterAnnotationsAsAttribute(ConstantPoolGen cp)`
    `int` | Instruction.`consumeStack(ConstantPoolGen cpg)` This method also gives right results for instructions whose effect on the stack depends on the constant pool entry they reference.
    `int` | InvokeInstruction.`consumeStack(ConstantPoolGen cpg)` Also works for instructions whose stack effect depends on the constant pool entry they reference.
    `int` | INVOKEINTERFACE.`consumeStack(ConstantPoolGen cpg)`
    `int` | MULTIANEWARRAY.`consumeStack(ConstantPoolGen cpg)` Also works for instructions whose stack effect depends on the constant pool entry they reference.
    `int` | PUTFIELD.`consumeStack(ConstantPoolGen cpg)`
    `int` | PUTSTATIC.`consumeStack(ConstantPoolGen cpg)`
    `int` | StackConsumer.`consumeStack(ConstantPoolGen cpg)`
    `FieldGen` | FieldGen.`copy(ConstantPoolGen cp)`
    `static ElementValueGen` | ElementValueGen.`copy(ElementValue value, ConstantPoolGen cpool, boolean copyPoolEntries)` Creates an (modifiable) ElementValueGen copy of an (immutable) ElementValue - constant pool is assumed correct.
    `MethodGen` | MethodGen.`copy(String class_name, ConstantPoolGen cp)`
    `Type[]` | InvokeInstruction.`getArgumentTypes(ConstantPoolGen cpg)`
    `String` | FieldOrMethod.`getClassName(ConstantPoolGen cpg)` Deprecated. If the instruction references an array class, this method will return "java.lang.Object". For code generated by Java 1.5, this answer is sometimes wrong (e.g., if the "clone()" method is called on an array). A better idea is to use the `FieldOrMethod.getReferenceType(ConstantPoolGen)` method, which correctly distinguishes between class types and array types.
    `String` | INVOKEDYNAMIC.`getClassName(ConstantPoolGen cpg)` Override the parent method because our classname is held elsewhere.
    `String` | InvokeInstruction.`getClassName(ConstantPoolGen cpg)` This overrides the deprecated version as we know here that the referenced class may legally be an array.
    `ObjectType` | FieldOrMethod.`getClassType(ConstantPoolGen cpg)` Deprecated. If the instruction references an array class, the ObjectType returned will be invalid. Use getReferenceType() instead.
    `CodeException` | CodeExceptionGen.`getCodeException(ConstantPoolGen cp)` Get CodeException object. This relies on that the instruction list has already been dumped to byte code or or that the `setPositions' methods has been called for the instruction list.
    `String` | FieldInstruction.`getFieldName(ConstantPoolGen cpg)`
    `protected int` | FieldInstruction.`getFieldSize(ConstantPoolGen cpg)`
    `Type` | FieldInstruction.`getFieldType(ConstantPoolGen cpg)`

    `ReferenceType` | FieldOrMethod.`getReferenceType(ConstantPoolGen cpg)` Gets the reference type representing the class, interface, or array class referenced by the instruction.
    `ReferenceType` | INVOKEDYNAMIC.`getReferenceType(ConstantPoolGen cpg)` Since InvokeDynamic doesn't refer to a reference type, just return java.lang.Object, as that is the only type we can say for sure the reference will be.
