Constructor Detail

JSRInlinerAdapter

public JSRInlinerAdapter(org.objectweb.asm.MethodVisitor mv,
                         int access,
                         java.lang.String name,
                         java.lang.String desc,
                         java.lang.String signature,
                         java.lang.String[] exceptions)

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

Parameters:

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 name.

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.

Throws:

java.lang.IllegalStateException - If a subclass calls this constructor.

JSRInlinerAdapter

protected JSRInlinerAdapter(int api,
                            org.objectweb.asm.MethodVisitor mv,
                            int access,
                            java.lang.String name,
                            java.lang.String desc,
                            java.lang.String signature,
                            java.lang.String[] exceptions)

Constructs a new JSRInliner.

Parameters:

api - the ASM API version implemented by this visitor. Must be one of Opcodes.ASM4, Opcodes.ASM5 or Opcodes.ASM6.

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 name.

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.

Method Detail

visitJumpInsn

public void visitJumpInsn(int opcode,
                          org.objectweb.asm.Label lbl)

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

Overrides:

visitJumpInsn in class org.objectweb.asm.tree.MethodNode

visitEnd

public void visitEnd()

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

Overrides:

visitEnd in class org.objectweb.asm.tree.MethodNode
