Method Details

accept
Call corresponding visitor method(s). The order is: Call visitor methods of implemented interfaces first, then call methods according to the class hierarchy in descending order, i.e., the most specific visitXXX() call comes last.- Specified by:
acceptin classInstruction- Parameters:
v- Visitor object
-
dump
Dump instruction as byte code to stream out.- Overrides:
dumpin classCPInstruction- Parameters:
out- Output stream- Throws:
IOException- Thrown when an I/O exception of some sort has occurred.
-
getExceptions
- Specified by:
getExceptionsin interfaceExceptionThrower
-
getType
- Specified by:
getTypein interfaceTypedInstruction- Overrides:
getTypein classCPInstruction- Returns:
- type related with this instruction.
-
getValue
-
initFromFile
Read needed data (e.g. index) from file.- Overrides:
initFromFilein classCPInstruction- Parameters:
bytes- input streamwide- wide prefix?- Throws:
IOException- may be thrown if the implementation needs to read data from the file
-
setIndex
Sets the index to constant pool and adjust size.- Specified by:
setIndexin interfaceIndexedInstruction- Overrides:
setIndexin classCPInstruction- Parameters:
index- in constant pool.
