Enclosing class:

NarrowingConversionInstruction

public static enum NarrowingConversionInstruction.NarrowingType
extends Enum<NarrowingConversionInstruction.NarrowingType>

The narrowing conversion kinds, each pairing a JVM opcode with its mnemonic.

Enum Constant Summary

Enum Constants

Enum Constant	Description
I2B	Truncates an int to 8 bits and sign-extends it back, the byte conversion.
I2C	Truncates an int to 16 bits and zero-extends it back, the char conversion.
I2S	Truncates an int to 16 bits and sign-extends it back, the short conversion.

Method Summary

Modifier and Type	Method	Description
static NarrowingConversionInstruction.NarrowingType	fromOpcode(int opcode)	Looks up the narrowing type for a JVM opcode.
String	getMnemonic()

Enum Constant Detail

I2B

public static final NarrowingConversionInstruction.NarrowingType I2B

Truncates an int to 8 bits and sign-extends it back, the byte conversion.

I2C

public static final NarrowingConversionInstruction.NarrowingType I2C

Truncates an int to 16 bits and zero-extends it back, the char conversion.

I2S

public static final NarrowingConversionInstruction.NarrowingType I2S

Truncates an int to 16 bits and sign-extends it back, the short conversion.

Method Detail

values

public static NarrowingConversionInstruction.NarrowingType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (NarrowingConversionInstruction.NarrowingType c : NarrowingConversionInstruction.NarrowingType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static NarrowingConversionInstruction.NarrowingType valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getOpcode

public int getOpcode()

Returns:

the opcode

getMnemonic

public String getMnemonic()

Returns:

the mnemonic

fromOpcode

public static NarrowingConversionInstruction.NarrowingType fromOpcode(int opcode)

Looks up the narrowing type for a JVM opcode.

Parameters:

opcode - the JVM opcode

Returns:

the matching type, or null if the opcode is not I2B, I2C, or I2S
