Method Detail

addLocalVariable

public org.apache.bcel.generic.LocalVariableGen addLocalVariable(java.lang.String name,
                                                        org.apache.bcel.generic.Type type,

Allocates a local variable. If the slot allocator has already been initialized, then call addLocalVariable2() so that the new variable is known to the allocator. Failing to do this may cause the allocator to return a slot that is already in use.
