Method Details
-
isPEI
public boolean isPEI()Description copied from interface:IInstruction
PEI == "Potentially excepting instruction"- Specified by:
isPEI
in interfaceIInstruction
- Returns:
- true iff this instruction might throw an exception
-
getInvocationCode
- Specified by:
getInvocationCode
in interfaceIInvokeInstruction
- Returns:
- one of BytecodeConstants.INVOKE[SPECIAL|VIRTUAL|STATIC|INTERFACE]
-
getPoppedCount
public final int getPoppedCount()- Specified by:
getPoppedCount
in interfaceIInstruction
- Overrides:
getPoppedCount
in classInstruction
- Returns:
- the number of values this instruction pops off the working stack
-
getPushedType
Description copied from class:Instruction
Computes the type of data pushed onto the stack, or null if none is pushed.- Specified by:
getPushedType
in interfaceIInstruction
- Overrides:
getPushedType
in classInstruction
- Parameters:
types
- the types of the data popped off the stack by this instruction; if poppedTypes is null, then we don't know the incoming stack types and the result of this method may be less accurate
-
getPushedWordSize
public final byte getPushedWordSize()- Specified by:
getPushedWordSize
in interfaceIInstruction
- Overrides:
getPushedWordSize
in classInstruction
- Returns:
- the JVM word size of the value this instruction pushes onto the stack, or 0 if this instruction doesn't push anything onto the stack.
