Class BCMethod

- org.apache.derby.impl.services.bytecode.BCMethod
-
- All Implemented Interfaces:
MethodBuilder
class BCMethod extends java.lang.Object implements MethodBuilder
MethodBuilder is used to piece together a method when building a java class definition.When a method is first created, it has:
- a return type
- modifiers
- a name
- an empty parameter list
- an empty throws list
- an empty statement block
MethodBuilder implementations are required to supply a way for Statements and Expressions to give them code. Most typically, they may have a stream to which their contents writes the code that is of the type to satisfy what the contents represent. MethodBuilder implementations also have to have a way to supply ClassBuilders with their code, that satisfies the type of class builder they are implemented with. This is implementation-dependent, so ClassBuilders, MethodBuilders, Statements, and Expressions all have to be of the same implementation in order to interact to generate a class.
Method Builder implementation for generating bytecode.

-
statementNumHitLimit
public boolean statementNumHitLimit(int noStatementsAdded)
Tell if statement number in this method builder hits limit. This method builder keeps a counter of how many statements are added to it. Caller should call this function every time it tries to add a statement to this method builder (counter is increased by 1), then the function returns whether the accumulated statement number hits a limit. The reason of doing this is that Java compiler has a limit of 64K code size for each method. We might hit this limit if an extremely long insert statement is issued, for example (see beetle 4293). Counting statement number is an approximation without too much overhead.- Specified by:
statementNumHitLimit

overflowMethodCheck
private void overflowMethodCheck()
Check to see if the current method byte code is nearing the limit of 65535. If it is start overflowing to a new method.Overflow is handled for a method named e23 as:

These overflow methods are hidden from the code using this MethodBuilder, it continues to think that it is building a single method with the original name.
Restrictions:- Only handles methods with no arguments
- Stack depth must be zero
-
