Method Detail

visitVarInsn

public void visitVarInsn(int opcode,
                         int var)

Description copied from interface: MethodVisitor

Visits a local variable instruction. A local variable instruction is an instruction that loads or stores the value of a local variable.

Specified by:

visitVarInsn in interface MethodVisitor

Overrides:

visitVarInsn in class MethodAdapter

Parameters:

opcode - the opcode of the local variable instruction to be visited. This opcode is either ILOAD, LLOAD, FLOAD, DLOAD, ALOAD, ISTORE, LSTORE, FSTORE, DSTORE, ASTORE or RET.

var - the operand of the instruction to be visited. This operand is the index of a local variable.

visitIincInsn

public void visitIincInsn(int var,
                          int increment)

Description copied from interface: MethodVisitor

Visits an IINC instruction.

Specified by:

visitIincInsn in interface MethodVisitor

Overrides:

visitIincInsn in class MethodAdapter

Parameters:

var - index of the local variable to be incremented.

increment - amount to increment the local variable by.

visitMaxs

public void visitMaxs(int maxStack,
                      int maxLocals)

Description copied from interface: MethodVisitor

Visits the maximum stack size and the maximum number of local variables of the method.

Specified by:

visitMaxs in interface MethodVisitor

Overrides:

visitMaxs in class MethodAdapter

Parameters:

maxStack - maximum stack size of the method.

maxLocals - maximum number of local variables for the method.

visitLocalVariable

public void visitLocalVariable(String name,
                               String desc,
                               String signature,
                               Label start,
                               Label end,
                               int index)

Description copied from interface: MethodVisitor

Visits a local variable declaration.

Specified by:

visitLocalVariable in interface MethodVisitor

Overrides:

visitLocalVariable in class MethodAdapter

Parameters:

name - the name of a local variable.

desc - the type descriptor of this local variable.

signature - the type signature of this local variable. May be null if the local variable type does not use generic types.

start - the first instruction corresponding to the scope of this local variable (inclusive).

end - the last instruction corresponding to the scope of this local variable (exclusive).

index - the local variable's index.
