Packages that use ReferenceType
Package
Description
org.apache.bcel.generic
Generic part of the Apache Byte Code Engineering Library (BCEL), classes to dynamically modify class objects and byte code instructions.
org.apache.bcel.verifier.structurals
A PassVerifier class mostly used internally by JustIce, yielding a control flow graph for public use as a nice side effect.

- ## Uses of ReferenceType in org.apache.bcel.generic

  Subclasses of ReferenceType in org.apache.bcel.generic
  Modifier and Type
  Class
  Description
  `final class`
  `ArrayType`
  Denotes array type, such as int[][]
  `class`
  `ObjectType`
  Denotes reference such as `String`.
  Fields in org.apache.bcel.generic declared as ReferenceType
  Modifier and Type
  Field
  Description
  `static final ReferenceType`
  Type.`NULL`
  Methods in org.apache.bcel.generic that return ReferenceType
  Modifier and Type
  Method
  Description
  `ReferenceType`
  ReferenceType.`firstCommonSuperclass(ReferenceType t)`
  Deprecated.
  Use getFirstCommonSuperclass(ReferenceType t) which has slightly changed semantics.
  `ReferenceType`
  ReferenceType.`getFirstCommonSuperclass(ReferenceType t)`
  This commutative operation returns the first common superclass (narrowest ReferenceType referencing a class, not an interface).
  `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 `Object`, as that is the only type we can say for sure the reference will be.
  Methods in org.apache.bcel.generic with parameters of type ReferenceType
  Modifier and Type
  Method
  Description
  `CHECKCAST`
  InstructionFactory.`createCheckCast(ReferenceType t)`
  `INSTANCEOF`
  InstructionFactory.`createInstanceOf(ReferenceType t)`
  `ReferenceType`
  ReferenceType.`firstCommonSuperclass(ReferenceType t)`
  Deprecated.
  Use getFirstCommonSuperclass(ReferenceType t) which has slightly changed semantics.
  `ReferenceType`
  ReferenceType.`getFirstCommonSuperclass(ReferenceType t)`
  This commutative operation returns the first common superclass (narrowest ReferenceType referencing a class, not an interface).
