Interface Subroutine
- All Known Implementing Classes:
- Subroutines.SubroutineImpl
- public interface Subroutine
This interface defines properties of JVM bytecode subroutines. Note that it is 'abused' to maintain the top-level code in a consistent fashion, too.
- Version:
- $Id: Subroutine.java 371539 2006-01-23 14:08:00Z tcurdt $
| Method Summary | |
boolean |
contains(org.apache.bcel.generic.InstructionHandle inst)
Returns if the given InstructionHandle refers to an instruction that is part of this subroutine. |
int[] |
getAccessedLocalsIndices()
Returns an int[] containing the indices of the local variable slots accessed by this Subroutine (read-accessed, write-accessed or both); local variables referenced by subroutines of this subroutine are not included. |
org.apache.bcel.generic.InstructionHandle[] |
getEnteringJsrInstructions()
Returns all the JsrInstructions that have the first instruction of this subroutine as their target. |
org.apache.bcel.generic.InstructionHandle[] |
getInstructions()
Returns all instructions that together form this subroutine. |
org.apache.bcel.generic.InstructionHandle |
getLeavingRET()
Returns the one and only RET that leaves the subroutine. |
int[] |
getRecursivelyAccessedLocalsIndices()
Returns an int[] containing the indices of the local variable slots accessed by this Subroutine (read-accessed, write-accessed or both); local variables referenced by subroutines of this subroutine are included. |
Subroutine[] |
subSubs()
Returns the subroutines that are directly called from this subroutine. |
| Method Detail |
getEnteringJsrInstructions
public org.apache.bcel.generic.InstructionHandle[] getEnteringJsrInstructions()
- Returns all the JsrInstructions that have the
first instruction of this subroutine as their target.
Must not be invoked on the 'top-level subroutine'.
getLeavingRET
public org.apache.bcel.generic.InstructionHandle getLeavingRET()
- Returns the one and only RET that leaves the subroutine.
Note that JustIce has a pretty rigid notion of a subroutine.
Must not be invoked on the 'top-level subroutine'.
getInstructions
public org.apache.bcel.generic.InstructionHandle[] getInstructions()
- Returns all instructions that together form this subroutine.
Note that an instruction is part of exactly one subroutine
(the top-level code is considered to be a special subroutine) -
else it is not reachable at all (dead code).
contains
public boolean contains(org.apache.bcel.generic.InstructionHandle inst)
- Returns if the given InstructionHandle refers to an instruction
that is part of this subroutine. This is a convenience method
that saves iteration over the InstructionHandle objects returned
by getInstructions().
getAccessedLocalsIndices
public int[] getAccessedLocalsIndices()
- Returns an int[] containing the indices of the local variable slots
accessed by this Subroutine (read-accessed, write-accessed or both);
local variables referenced by subroutines of this subroutine are
not included.
getRecursivelyAccessedLocalsIndices
public int[] getRecursivelyAccessedLocalsIndices()
- Returns an int[] containing the indices of the local variable slots
accessed by this Subroutine (read-accessed, write-accessed or both);
local variables referenced by subroutines of this subroutine are
included.
subSubs
public Subroutine[] subSubs()
- Returns the subroutines that are directly called from this subroutine.
