Method Detail
-
getLength
int getLength()
Description copied from class:Instruction
Return the length in bytes of this opcode, including all arguments. For many opcodes this method relies on an up-to-date byte index.- Overrides:
getLength
in classInstruction
-
getTypeName
public java.lang.String getTypeName()
Description copied from class:TypedInstruction
Return the type name for this instruction. If the type has not been set, this method will return null.- Specified by:
getTypeName
in classTypedInstruction
-
setType
public TypedInstruction setType(java.lang.String type)
Description copied from class:TypedInstruction
Set the type of this instruction. Types that have no direct support will be converted accordingly.- Specified by:
setType
in classTypedInstruction
- Returns:
- this instruction, for method chaining
-
getTypeCode
public int getTypeCode()
Return the array code used in the lowlevel bytecode, or -1 if unset.
-
setTypeCode
public NewArrayInstruction setTypeCode(int code)
Set the array code used in the lowlevel bytecode.- Returns:
- this instruction, for method chaining
-
equalsInstruction
public boolean equalsInstruction(Instruction other)
NewArray instructions are equal if the array type is the same, of if the array type of either is unset.- Overrides:
equalsInstruction
in classInstruction
-
acceptVisit
public void acceptVisit(BCVisitor visit)
Description copied from interface:VisitAcceptor
Accept a visit from aBCVisitor
, calling the appropriate methods to notify the visitor that it has entered this entity, and to provide it with the proper callbacks for each sub-entity owned by this one.- Specified by:
acceptVisit
in interfaceVisitAcceptor
- Overrides:
acceptVisit
in classInstruction
-
read
void read(Instruction orig)
Description copied from class:Instruction
Copy the given instruction data.- Overrides:
read
in classInstruction
-
read
void read(java.io.DataInput in) throws java.io.IOException
Description copied from class:Instruction
Read the arguments for this opcode from the given stream. This method should be overridden by opcodes that take arguments.- Overrides:
read
in classInstruction
- Throws:
java.io.IOException
-
write
void write(java.io.DataOutput out) throws java.io.IOException
Description copied from class:Instruction
Write the arguments for this opcode to the given stream. This method should be overridden by opcodes that take arguments.- Overrides:
write
in classInstruction
- Throws:
java.io.IOException
