Method Summary

Modifier and Type	Method	Description
void	acceptVisit(BCVisitor visit)	Accept a visit from a BCVisitor, 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.
boolean	equalsInstruction(Instruction other)	NewArray instructions are equal if the array type is the same, of if the array type of either is unset.
(package private) int	getLength()	Return the length in bytes of this opcode, including all arguments.
int	getTypeCode()	Return the array code used in the lowlevel bytecode, or -1 if unset.
java.lang.String	getTypeName()	Return the type name for this instruction.
(package private) void	read(java.io.DataInput in)	Read the arguments for this opcode from the given stream.
(package private) void	read(Instruction orig)	Copy the given instruction data.
TypedInstruction	setType(java.lang.String type)	Set the type of this instruction.
NewArrayInstruction	setTypeCode(int code)	Set the array code used in the lowlevel bytecode.
(package private) void	write(java.io.DataOutput out)	Write the arguments for this opcode to the given stream.

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 class Instruction

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 class TypedInstruction

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 class TypedInstruction

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 class Instruction

acceptVisit

public void acceptVisit(BCVisitor visit)

Description copied from interface: VisitAcceptor

Accept a visit from a BCVisitor, 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 interface VisitAcceptor

Overrides:

acceptVisit in class Instruction

read

void read(Instruction orig)

Description copied from class: Instruction

Copy the given instruction data.

Overrides:

read in class Instruction

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 class Instruction

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 class Instruction

Throws:

java.io.IOException
