All known Subclasses: org.objectweb.asm.commons.GeneratorAdapter, org.objectweb.asm.commons.RemappingMethodAdapter,
| LocalVariablesSorter | | public class LocalVariablesSorter extends MethodAdapter (Code) | | A
MethodAdapter that renumbers local variables in their order of
appearance. This adapter allows one to easily add new local variables to a
method. It may be used by inheriting from this class, but the preferred way
of using it is via delegation: the next visitor in the chain can indeed add
new locals when needed by calling
LocalVariablesSorter.newLocal on this adapter (this
requires a reference back to this
LocalVariablesSorter ).

| Method Summary | |
| public int | newLocal(Type type)
Creates a new local variable of the given type.
Parameters:
type - the type of the local variable to be created. | | protected int | newLocalMapping(Type type)
| | protected void | setLocalType(int local, Type type)
Sets the current type of the given local variable. | | public void | visitFrame(int type, int nLocal, Object[] local, int nStack, Object[] stack)
| | public void | visitIincInsn(int var, int increment)
| | public void | visitLocalVariable(String name, String desc, String signature, Label start, Label end, int index)
| | public void | visitMaxs(int maxStack, int maxLocals)
| | public void | visitVarInsn(int opcode, int var)
|
| firstLocal | | final protected int firstLocal(Code) | | Index of the first local variable, after formal parameters.
|
| LocalVariablesSorter | | public LocalVariablesSorter(int access, String desc, MethodVisitor mv)(Code) | | Creates a new
LocalVariablesSorter .
Parameters:
access - access flags of the adapted method.
Parameters:
desc - the method's descriptor (see Type Type).
Parameters:
mv - the method visitor to which this adapter delegates calls. |
| newLocal | | public int newLocal(Type type)(Code) | | Creates a new local variable of the given type.
Parameters:
type - the type of the local variable to be created. the identifier of the newly created local variable. |
| newLocalMapping | | protected int newLocalMapping(Type type)(Code) | | |
| setLocalType | | protected void setLocalType(int local, Type type)(Code) | | Sets the current type of the given local variable. The default
implementation of this method does nothing.
Parameters:
local - a local variable identifier, as returned by LocalVariablesSorter.newLocalnewLocal().
Parameters:
type - the type of the value being stored in the local variable |
