Method Summary¶

Owner	Name	Return Type	Description
Long	constructor(value)	Object	Initialize a Long object.
Long	byteValue()	Byte	Returns the value of this Long as a Byte after a narrowing primitive conversion.
Object	getClassName()	String	Returns the string name of this object's class type.
Long	highestOneBit()	Long	Returns a Long value with a single one-bit in the position of the highest-order ("leftmost") one-bit of this Long, or 0 if the value supplied is 0.
Long	lowestOneBit()	Long	Returns a Long value with a single one-bit in the position of the lowest-order ("rightmost") one-bit of the supplied long value, or 0 if the value supplied is 0.
Long	numberOfLeadingZeros()	Integer	Returns the number of zero bits preceding the highest-order ("leftmost") one-bit in the two's complement binary representation of this Long.
Long	numberOfTrailingZeros()	Integer	Returns the number of zero bits following the lowest-order ("rightmost") one-bit in the two's complement binary representation of this Long.
Object	toJson()	String	Returns a string of a json representation of this object.

Method Definitions¶

constructor(value)¶

Long long = new Long(Long value)

Description¶

Initialize a Long object.

Parameter Definition¶

Name	Type	Description
value	Long	a long value

Example 1¶

Long l = 100l;

// l = 100

byteValue()¶

Byte Long::byteValue()

Description¶

Returns the value of this Long as a Byte after a narrowing primitive conversion.

Example 1¶

Long l = 100;
l.byteValue();

// l.byteValue() = 100

getClassName()¶

String Object::getClassName()

Description¶

Returns the string name of this object's class type.

Example 6¶

Long l = 100;
l.getClassName();

// l.getClassName() = Long

highestOneBit()¶

Long Long::highestOneBit()

Description¶

Returns a Long value with a single one-bit in the position of the highest-order ("leftmost") one-bit of this Long, or 0 if the value supplied is 0.

Example 1¶

Long l = 100;
l.highestOneBit();

// l.highestOneBit() = 64

lowestOneBit()¶

Long Long::lowestOneBit()

Description¶

Returns a Long value with a single one-bit in the position of the lowest-order ("rightmost") one-bit of the supplied long value, or 0 if the value supplied is 0.

Example 1¶

Long l = 100;
l.lowestOneBit();

// l.lowestOneBit() = 4

numberOfLeadingZeros()¶

Integer Long::numberOfLeadingZeros()

Description¶

Returns the number of zero bits preceding the highest-order ("leftmost") one-bit in the two's complement binary representation of this Long.

Example 1¶

Long l = 100;
l.numberOfLeadingZeros();

// l.numberOfLeadingZeros() = 57

numberOfTrailingZeros()¶

Integer Long::numberOfTrailingZeros()

Description¶

Returns the number of zero bits following the lowest-order ("rightmost") one-bit in the two's complement binary representation of this Long.

Example 1¶

Long l= 100;
l.numberOfTrailingZeros();

// l.numberOfTrailingZeros() = 2

toJson()¶

String Object::toJson()

Description¶

Returns a string of a json representation of this object.

Example 6¶

Long l = 100;
l.toJson();

// l.toJson() = 100
