public boolean equals(Object other)

Overrides java.lang.Object.equals.

Doc from java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
other:Object

the reference object with which to compare.

Returns:boolean

true if this object is the same as the obj argument; false otherwise.

hashCodeback to summary
public int hashCode()

Overrides java.lang.Object.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for this object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
Returns:int

a hash code value for this object

public static ConfigMemorySize ofBytes(BigInteger bytes)

Constructs a ConfigMemorySize representing the given number of bytes.

Parameters
bytes:BigInteger

a number of bytes

Returns:ConfigMemorySize

an instance representing the number of bytes

Since
1.3.0
ofBytesback to summary
public static ConfigMemorySize ofBytes(long bytes)

Constructs a ConfigMemorySize representing the given number of bytes.

Parameters
bytes:long

a number of bytes

Returns:ConfigMemorySize

an instance representing the number of bytes

toBytesback to summary
public long toBytes()

Gets the size in bytes.

Returns:long

how many bytes

Exceptions
IllegalArgumentException:
when memory value in bytes doesn't fit in a long value. Consider using toBytesBigInteger in this case.
Since
1.3.0
toBytesBigIntegerback to summary
public BigInteger toBytesBigInteger()

Gets the size in bytes. The behavior of this method is the same as that of the toBytes() method, except that the number of bytes returned as a BigInteger value. Use it when memory value in bytes doesn't fit in a long value.

Returns:BigInteger

how many bytes

toStringback to summary
public String toString()

Overrides java.lang.Object.toString.

Doc from java.lang.Object.toString.

Returns a string representation of the object. Satisfying this method's contract implies a non-null result must be returned.

Returns:String

a string representation of the object
