```
public abstract class MethodBuilder
extends BindingMethod
```
Method builder. Organizes and tracks the creation of a method, providing convenience methods for common operations. This is customized for the needs of JiBX, with some predetermined settings as appropriate. It supplies hash code and equality checking based on the method signature and actual byte code of the generated method, ignoring the method name.

    Instruction handle
  - isStackTopLong

    Returns:
    
    true if long value, false if not
  - initStackState
```
public void initStackState(BranchWrapper branch)
```
    Initialize stack state to match branch source. This can be used to set the expected stack state following an unconditional transfer of control instruction. The principle here is that the code to be generated must be reached by a branch, so the stack state must match that of the branch source.
    
    Parameters:
    
    branch - wrapper for branch to be for stack initialization
  - initStackState
```
public void initStackState(BranchWrapper branch,
                           int pop)
```
    Initialize stack state to partially match branch source. This can be used to set the expected stack state following an unconditional transfer of control instruction. The specified number of items are removed from the branch stack, with the assumption that code to add these items will be appended before the branch join point is reached.
    
    Parameters:
    
    branch - wrapper for branch to be for stack initialization
    
    pop - number of items to be removed from branch source stack state
  - initStackState
```
protected void initStackState(String[] types)
```
    Initialize stack state to array of value types. This can be used to set the expected stack state following an unconditional transfer of control instruction.
    
    Parameters:
    
    types - array of type names on stack
  - targetNext
```
public void targetNext(BranchWrapper branch)
```
    Set branch target as next instruction added to method. This effectively sets up a state trigger for the next append operation. The appended instruction is set as the target for the branch. This requires that instructions are only appended using the methods supplied in this class.
    
    Parameters:
    
    branch - wrapper for branch to be aimed at next instruction (may be null, in which case nothing is done)
  - targetNext
```
public void targetNext(BranchWrapper[] branches)
```
    Set branch targets as next instruction added to method. This effectively sets up a state trigger for the next append operation. The appended instruction is set as the target for all the branches. This requires that instructions are only appended using the methods supplied in this class.
    
    Parameters:
    
    branches - wrappers for branches to be aimed at next instruction (may be null, in which case nothing is done)
  - handleExceptions
```
protected abstract void handleExceptions()
```
    Process accumulated exceptions. Each subclass must implement this method to perform the appropriate handling of the checked exceptions that may be thrown in the constructed method.
  - codeComplete
```
public void codeComplete(boolean suffix)
```
    Complete method construction. Finalizes the instruction list and generates the byte code for the constructed method, then computes the hash code based on the byte code. If requested, an appropriate suffix is tacked on the end of the supplied name in order to make sure that it will not be duplicated (even in a superclass or subclass).
    
    Parameters:
    
    suffix - add suffix to make method name unique
  - getItem
```
public ClassItem getItem()
```
    Get the method item.
    
    Specified by:
    
    getItem in class BindingMethod
    
    Returns:
    
    method item information
  - hashCode
```
public int hashCode()
```
    Get hash code. This is based only on the byte code in the method, and is only valid after the codeComplete(boolean) method is called.
    
    Specified by:
    
    hashCode in class BindingMethod
    
    Returns:
    
    hash code based on code sequence
  - addMethod
```
public ClassItem addMethod()
```
    Add constructed method to class. Makes the method callable, generating the method information.
    
    Returns:
    
    added method information
