| Method Summary | |
| public void | add(int offset, byte[] buffer, int bufOffset, int length)
Adds a byte to the code. | | public void | addByte(int offset, int value)
Adds a byte to the code. | | public void | addNulls(int offset, int count)
Adds a byte to the code. | | public void | addShort(int offset, int value)
Adds a short to the code. | | public void | analyze(Analyzer analyzer, boolean allowFlow)
| | protected void | analyzeJumps()
| | public byte[] | getCode()
Returns the code buffer. | | public int | getLength()
Returns the length. | | public void | init(JavaClass javaClass, CodeAttribute codeAttr)
| | protected void | insertCode(int offset, int count)
Updates indices when adding a chunk of code. | | public void | remove(int offset, int count)
Removes a range from the code. | | protected void | removeCode(int offset, int count)
| | public void | setByte(int offset, int value)
Adds a byte to the code. | | public void | update()
Updates the code. |
| CodeEnhancer | | public CodeEnhancer()(Code) | | |
| add | | public void add(int offset, byte[] buffer, int bufOffset, int length)(Code) | | Adds a byte to the code.
|
| addByte | | public void addByte(int offset, int value)(Code) | | Adds a byte to the code.
|
| addNulls | | public void addNulls(int offset, int count)(Code) | | Adds a byte to the code.
|
| addShort | | public void addShort(int offset, int value)(Code) | | Adds a short to the code.
|
| analyze | | public void analyze(Analyzer analyzer, boolean allowFlow) throws Exception(Code) | | Analyzes the code for a method
|
| analyzeJumps | | protected void analyzeJumps()(Code) | | |
| getCode | | public byte[] getCode()(Code) | | Returns the code buffer.
|
| getLength | | public int getLength()(Code) | | Returns the length.
|
| insertCode | | protected void insertCode(int offset, int count)(Code) | | Updates indices when adding a chunk of code. The operation at
the given offset moves, e.g. adding 6 bytes to the beginning of
the program moves the initial byte down by 6 and therefore needs
to update the links as well.
Therefore, enhancers which expand an opcode from 2 bytes to 3 bytes
must insert the new bytes after the initial opcode.
|
| remove | | public void remove(int offset, int count)(Code) | | Removes a range from the code.
|
| removeCode | | protected void removeCode(int offset, int count)(Code) | | |
| setByte | | public void setByte(int offset, int value)(Code) | | Adds a byte to the code.
|
| update | | public void update()(Code) | | Updates the code.
