类 LibraryClassBuilder

java.lang.Object
proguard.classfile.editor.LibraryClassBuilder
public class LibraryClassBuilder extends Object
This editor allows to build or extend classes (LibraryClass instances). It provides methods to easily add interfaces, fields, and methods, optionally with method bodies.

If you're adding many fields and methods, it is more efficient to reuse a single instance of this builder for all fields and methods that you add.

    • LibraryClassBuilder

      public LibraryClassBuilder(LibraryClass libraryClass)
      Creates a new ClassBuilder for the given class.
      参数:
      libraryClass - the class to be edited.

  • 方法详细资料

    • getLibraryClass

      public LibraryClass getLibraryClass()
      Returns the created or edited LibraryClass instance. This is a live instance; any later calls to the builder will still affect the instance.

    • getConstantPoolEditor

      public ConstantPoolEditor getConstantPoolEditor()
      Returns a ConstantPoolEditor instance for the created or edited class instance. Reusing this instance is more efficient for newly created classes.

    • addInterface

      public LibraryClassBuilder addInterface(Clazz interfaceClass)
      Adds a new interface to the edited class.
      参数:
      interfaceClass - the interface class.
      返回:
      this instance of ClassBuilder.

    • addInterface

      public LibraryClassBuilder addInterface(String interfaceName)
      Adds a new interface to the edited class.
      参数:
      interfaceName - the name of the interface.
      返回:
      this instance of ClassBuilder.

    • addInterface

      public LibraryClassBuilder addInterface(String interfaceName, Clazz referencedInterface)
      Adds a new interface to the edited class.
      参数:
      interfaceName - the name of the interface.
      referencedInterface - the referenced interface.
      返回:
      this instance of ClassBuilder.

    • addField

      public LibraryClassBuilder addField(int u2accessFlags, String fieldName, String fieldDescriptor)
      Adds a new field to the edited class.
      参数:
      u2accessFlags - access flags for the new field.
      fieldName - name of the new field.
      fieldDescriptor - descriptor of the new field.
      返回:
      this instance of ClassBuilder.

    • addField

      参数:
      u2accessFlags - access flags for the new field.
      fieldName - name of the new field.
      fieldDescriptor - descriptor of the new field.
      返回:

    • addAndReturnField

      public LibraryField addAndReturnField(int u2accessFlags, String fieldName, String fieldDescriptor)
      Adds a new field to the edited class, and returns it.
      参数:
      u2accessFlags - access flags for the new field.
      fieldName - name of the new field.
      fieldDescriptor - descriptor of the new field.
      返回:
