Method Detail

flush

protected void flush()

Specified by:

flush in class AbstractMethodVisitor

visitLabel

public void visitLabel(Label label)

Description copied from interface: MethodVisitor

Visits a label. A label designates the instruction that will be visited just after it.

Specified by:

visitLabel in interface MethodVisitor

Overrides:

visitLabel in class AbstractMethodVisitor

Parameters:

label - a Label object.

visitJumpInsn

public void visitJumpInsn(int opcode,
                          Label label)

Description copied from interface: MethodVisitor

Visits a jump instruction. A jump instruction is an instruction that may jump to another instruction.

Specified by:

visitJumpInsn in interface MethodVisitor

Overrides:

visitJumpInsn in class AbstractMethodVisitor

Parameters:

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.

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

visitLookupSwitchInsn

public void visitLookupSwitchInsn(Label dflt,
                                  int[] keys,
                                  Label[] labels)

Description copied from interface: MethodVisitor

Visits a LOOKUPSWITCH instruction.

Specified by:

visitLookupSwitchInsn in interface MethodVisitor

Overrides:

visitLookupSwitchInsn in class AbstractMethodVisitor

Parameters:

dflt - beginning of the default handler block.

keys - the values of the keys.

labels - beginnings of the handler blocks. labels[i] is the beginning of the handler block for the keys[i] key.

visitTableSwitchInsn

public void visitTableSwitchInsn(int min,
                                 int max,
                                 Label dflt,
                                 Label[] labels)

Description copied from interface: MethodVisitor

Visits a TABLESWITCH instruction.

Specified by:

visitTableSwitchInsn in interface MethodVisitor

Overrides:

visitTableSwitchInsn in class AbstractMethodVisitor

Parameters:

min - the minimum key value.

max - the maximum key value.

dflt - beginning of the default handler block.

labels - beginnings of the handler blocks. labels[i] is the beginning of the handler block for the min + i key.

saveFrames

private void saveFrames(Label label,
                        Label[] labels)

saveFrame

private void saveFrame(Label label)

visitTypeInsn

Overrides:

visitTypeInsn in class AbstractMethodVisitor

Parameters:

opcode - the opcode of the type instruction to be visited. This opcode is either NEW, ANEWARRAY, CHECKCAST or INSTANCEOF.

desc - the operand of the instruction to be visited. This operand is must be a fully qualified class name in internal form, or the type descriptor of an array type (see Type).
