getLocalVariables
public LocalVariable[] getLocalVariables()
Return all the locals of this method.
-
getLocalVariable
public LocalVariable getLocalVariable(int local)
Return the local with the given locals index, or null if none.
-
getLocalVariable
public LocalVariable getLocalVariable(java.lang.String name)
Return the local with the given name, or null if none. If multiple locals have the given name, which is returned is undefined.
-
getLocalVariables
public LocalVariable[] getLocalVariables(java.lang.String name)
Return all locals with the given name, or empty array if none.
-
addLocalVariable
public LocalVariable addLocalVariable(LocalVariable local)
Import a local from another method/class. Note that the program counter and length from the given local is copied directly, and thus will be incorrect unless this method is the same as the one the local is copied from, or the pc and length are reset.
