DoubleWord
- Instruction

Constructors

constructor

new Instruction(value: Bit[]): Instruction
Instantiates a new object.
Parameters
- value: Bit[]
Returns Instruction
Overrides DoubleWord.constructor
- Defined in src/types/binary/Instruction.ts:13

Properties

`Static` `Readonly`MAX_NEGATIVE_NUMBER_DEC

MAX_NEGATIVE_NUMBER_DEC: number = -2_147_483_648

`Static` `Readonly`MAX_POSITIVE_NUMBER_DEC

MAX_POSITIVE_NUMBER_DEC: number = 2_147_483_647

`Static` `Readonly`NUMBER_OF_BITS_DEC

NUMBER_OF_BITS_DEC: number = 32

`Protected`_value

_value: Bit[]

An array of bits, representing a binary value.

Accessors

value

get value(): Bit[]
Accessor for reading the binary value.

Returns Bit[]
Overrides DoubleWord.value
- Defined in src/types/binary/Instruction.ts:21
set value(newValue: Bit[]): void
Accessor for setting the binary value.
Parameters
- newValue: Bit[]
  The new value.
Returns void
Overrides DoubleWord.value
- Defined in src/types/binary/Instruction.ts:30

Methods

`Static`fromInteger

fromInteger(integer: number): DoubleWord
This method creates an instance from the given number. Throws an error, if the given number is not an integer.
Parameters
- integer: number
  The number to initialize the new instances value with.
Returns DoubleWord
A new instance.
Inherited from DoubleWord.fromInteger
- Defined in src/types/binary/DoubleWord.ts:143

equal

equal(other: Instruction): boolean
For comparison, both binary values are converted to strings. Conversion presarves the order of items, which is important for the comparison.
Parameters
- other: Instruction
  The instruction to compare to.
Returns boolean
True, when both binary values are identical, false otherwise.
Overrides DoubleWord.equal
- Defined in src/types/binary/Instruction.ts:43

getLeastSignificantBit

getLeastSignificantBit(): Bit
This method returns the least significant bit of this value.

Returns Bit
The least significant bit.
Inherited from DoubleWord.getLeastSignificantBit
- Defined in src/types/binary/BinaryValue.ts:44

getLeastSignificantBits

getLeastSignificantBits(nbrOfBits: number): Bit[]
This method returns the last bits of the binary value. The number of bits returned depends on the argument passed.
Parameters
- nbrOfBits: number
Returns Bit[]
Inherited from DoubleWord.getLeastSignificantBits
- Defined in src/types/binary/BinaryValue.ts:84

getLeastSignificantByte

getLeastSignificantByte(): Bit[]
This method returns the least significant byte of this value.

Returns Bit[]
The least significant byte.
Inherited from DoubleWord.getLeastSignificantByte
- Defined in src/types/binary/BinaryValue.ts:60

getMostSignificantBit

getMostSignificantBit(): Bit
This method returns the most significant bit of this value.

Returns Bit
The most significant bit.
Inherited from DoubleWord.getMostSignificantBit
- Defined in src/types/binary/BinaryValue.ts:52

getMostSignificantBits

getMostSignificantBits(nbrOfBits: number): Bit[]
This method returns the first bits of the binary value. The number of bits returned depends on the argument passed.
Parameters
- nbrOfBits: number
Returns Bit[]
Inherited from DoubleWord.getMostSignificantBits
- Defined in src/types/binary/BinaryValue.ts:97

getMostSignificantByte

getMostSignificantByte(): Bit[]
This method returns the least significant byte of this value.

Returns Bit[]
The least significant byte.
Inherited from DoubleWord.getMostSignificantByte
- Defined in src/types/binary/BinaryValue.ts:71

isGreaterThan

isGreaterThan(other: DoubleWord): boolean
This method checks whether the current binary value is greater than the given one.
Parameters
- other: DoubleWord
  The binary value to compare to.
Returns boolean
True, if this value is greater than the one compared to, false otherwise.
Inherited from DoubleWord.isGreaterThan
- Defined in src/types/binary/DoubleWord.ts:86

isNegative

isNegative(): boolean
This method checks whether this binary value represents a negative number.

Returns boolean
True, if the most significant bit is set to 1, false otherwise.
Inherited from DoubleWord.isNegative
- Defined in src/types/binary/DoubleWord.ts:110

isNotZero

isNotZero(): boolean
This method checks whether the current binary value is not a binary zero or not.

Returns boolean
True, if the binary value is not zero, false otherwise.
Inherited from DoubleWord.isNotZero
- Defined in src/types/binary/DoubleWord.ts:102

isPositive

isPositive(): boolean
This method checks whether this binary value represents a positive number.

Returns boolean
True, if the most significant bit is set to 0, false otherwise.
Inherited from DoubleWord.isPositive
- Defined in src/types/binary/DoubleWord.ts:118

isSmallerThan

isSmallerThan(other: DoubleWord): boolean
This method checks whether the current binary value is smaller than the given one.
Parameters
- other: DoubleWord
  The binary value to compare to.
Returns boolean
True, if this value is less than the one compared to, false otherwise.
Inherited from DoubleWord.isSmallerThan
- Defined in src/types/binary/DoubleWord.ts:77

isZero

isZero(): boolean
This method checks whether the current binary value is a binary zero or not.

Returns boolean
True, if the binary value is zero, false otherwise.
Inherited from DoubleWord.isZero
- Defined in src/types/binary/DoubleWord.ts:94

toString

toString(groupBytes?: boolean): string
Converts the binary value into a string representation.
Parameters
- groupBytes: boolean = false
Returns string
The string representation of the binary value.
Overrides DoubleWord.toString
- Defined in src/types/binary/Instruction.ts:51
