Method Details

getBytecodeIndex

public int getBytecodeIndex()

Description copied from interface: Opcode

Return the bytecode index of the instruction, which can be used to identify the instruction as the target of a jump.

Specified by:

getBytecodeIndex in interface Opcode

Returns:

The bytecode index of the instruction, which is defined as the number of instructions before it in the instruction listing.

getStackMetadataAfterInstructionForBranches

public List<StackMetadata> getStackMetadataAfterInstructionForBranches(FunctionMetadata functionMetadata,
 StackMetadata stackMetadata)

Description copied from interface: Opcode

Return a list of StackMetadata corresponding to each branch returned by Opcode.getPossibleNextBytecodeIndexList().

Specified by:

getStackMetadataAfterInstructionForBranches in interface Opcode

Parameters:

functionMetadata - Metadata about the function being compiled.

stackMetadata - the StackMetadata just before this instruction is executed.

Returns:

a new List, the same size as Opcode.getPossibleNextBytecodeIndexList(), containing the StackMetadata after this instruction is executed for the given branch in Opcode.getPossibleNextBytecodeIndexList().

implement

public void implement(FunctionMetadata functionMetadata,
 StackMetadata stackMetadata)

Description copied from interface: Opcode

Implements the opcode.

Specified by:

implement in interface Opcode

Parameters:

functionMetadata - Metadata about the function being compiled.

stackMetadata - Metadata about the state of the stack when this instruction is executed.

isJumpTarget

public boolean isJumpTarget()

Specified by:

isJumpTarget in interface Opcode

Returns:

true if this opcode the target of a jump

equals

public boolean equals(Object other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
