dump
Dump instruction as byte code to stream out.- Overrides:
dumpin classInstruction- Parameters:
out- Output stream- Throws:
IOException- Thrown when an I/O exception of some sort has occurred.
-
getIndex
- Specified by:
getIndexin interfaceIndexedInstruction- Returns:
- index in constant pool referred by this instruction.
-
getType
- Specified by:
getTypein interfaceTypedInstruction- Returns:
- type related with this instruction.
-
initFromFile
Read needed data (i.e., index) from file.- Overrides:
initFromFilein classInstruction- 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.- Specified by:
setIndexin interfaceIndexedInstruction- Parameters:
index- in constant pool.
-
toString
Long output format: <name of opcode> "["<opcode number>"]" "("<length of instruction>")" "<"< constant pool index>">"- Overrides:
toStringin classInstruction- Parameters:
verbose- long/short format switch- Returns:
- mnemonic for instruction
-
toString
- Overrides:
toStringin classInstruction- Returns:
- mnemonic for instruction with symbolic references resolved
