构造器详细资料

Textifier

public Textifier()

Constructs a new Textifier. Subclasses must not use this constructor. Instead, they must use the Textifier(int) version.

抛出:

IllegalStateException - If a subclass calls this constructor.

Textifier

protected Textifier(int api)

Constructs a new Textifier.

参数:

api - the ASM API version implemented by this visitor. Must be one of Opcodes.ASM4 or Opcodes.ASM5.
