构造器详细资料

JSRInlinerAdapter

public JSRInlinerAdapter(MethodVisitor mv,
 int access,
 String name,
 String desc,
 String signature,
 String[] exceptions)

Creates a new JSRInliner. Subclasses must not use this constructor. Instead, they must use the JSRInlinerAdapter(int, MethodVisitor, int, String, String, String, String[]) version.

参数:

mv - the MethodVisitor to send the resulting inlined method code to (use null for none).

access - the method's access flags (see Opcodes). This parameter also indicates if the method is synthetic and/or deprecated.

name - the method's className.

desc - the method's descriptor (see Type).

signature - the method's signature. May be null.

exceptions - the internal names of the method's exception classes (see getInternalName). May be null.

抛出:

IllegalStateException - If a subclass calls this constructor.

JSRInlinerAdapter

protected JSRInlinerAdapter(int api,
 MethodVisitor mv,
 int access,
 String name,
 String desc,
 String signature,
 String[] exceptions)

Creates a new JSRInliner.

参数:

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

mv - the MethodVisitor to send the resulting inlined method code to (use null for none).

access - the method's access flags (see Opcodes). This parameter also indicates if the method is synthetic and/or deprecated.

name - the method's className.

desc - the method's descriptor (see Type).

signature - the method's signature. May be null.

exceptions - the internal names of the method's exception classes (see getInternalName). May be null.

方法详细资料

visitJumpInsn

public void visitJumpInsn(int opcode,
 Label lbl)

Detects a JSR instruction and sets a flag to indicate we will need to do inlining.

覆盖:

visitJumpInsn 在类中 MethodNode

参数:

opcode - the opcode of the type instruction to be visited. This opcode is either IFEQ, IFNE, IFLT, IFGE, IFGT, IFLE, IF_ICMPEQ, IF_ICMPNE, IF_ICMPLT, IF_ICMPGE, IF_ICMPGT, IF_ICMPLE, IF_ACMPEQ, IF_ACMPNE, GOTO, JSR, IFNULL or IFNONNULL.

lbl - the operand of the instruction to be visited. This operand is a label that designates the instruction to which the jump instruction may jump.

visitEnd

public void visitEnd()

If any JSRs were seen, triggers the inlining process. Otherwise, forwards the byte codes untouched.
