Implements com.google.common.hash.HashFunction.bits.

Doc from com.google.common.hash.HashFunction.bits.

Returns the number of bits (a multiple of 32) that each hash code produced by this hash function has.

@Override

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

object:Object

the reference object with which to compare.

Returns:boolean

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

@Override

Overrides com.google.common.hash.AbstractHashFunction.hashBytes.

Implements com.google.common.hash.HashFunction.hashBytes.

Doc from com.google.common.hash.HashFunction.hashBytes.

Shortcut for newHasher().putBytes(input, off, len).hash(). The implementation might perform better than its longhand equivalent, but should not perform worse.

Annotations

@Override

Overrides java.lang.Object.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for the 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.

@Override

Overrides com.google.common.hash.AbstractHashFunction.hashInt.

Implements com.google.common.hash.HashFunction.hashInt.

Doc from com.google.common.hash.HashFunction.hashInt.

Shortcut for newHasher().putInt(input).hash(); returns the hash code for the given int value, interpreted in little-endian byte order. The implementation might perform better than its longhand equivalent, but should not perform worse.

Annotations

@Override

Overrides com.google.common.hash.AbstractHashFunction.hashLong.

Implements com.google.common.hash.HashFunction.hashLong.

Doc from com.google.common.hash.HashFunction.hashLong.

Shortcut for newHasher().putLong(input).hash(); returns the hash code for the given long value, interpreted in little-endian byte order. The implementation might perform better than its longhand equivalent, but should not perform worse.

Annotations

@Override

Overrides com.google.common.hash.AbstractHashFunction.hashString.

Implements com.google.common.hash.HashFunction.hashString.

Doc from com.google.common.hash.HashFunction.hashString.

Shortcut for newHasher().putString(input, charset).hash(). Characters are encoded using the given Charset. The implementation might perform better than its longhand equivalent, but should not perform worse.

Annotations

@SuppressWarnings:deprecation

@Override

Overrides com.google.common.hash.AbstractHashFunction.hashUnencodedChars.

Implements com.google.common.hash.HashFunction.hashUnencodedChars.

Doc from com.google.common.hash.HashFunction.hashUnencodedChars.

Shortcut for newHasher().putUnencodedChars(input).hash(). The implementation might perform better than its longhand equivalent, but should not perform worse. Note that no character encoding is performed; the low byte and high byte of each char are hashed directly (in that order).

Annotations

@Override

Implements com.google.common.hash.HashFunction.newHasher.

Doc from com.google.common.hash.HashFunction.newHasher.

Begins a new hash code computation by returning an initialized, stateful Hasher instance that is ready to receive data. Example:

HashFunction hf = Hashing.md5();
HashCode hc = hf.newHasher()
    .putLong(id)
    .putBoolean(isActive)
    .hash();

Annotations

@Override

Overrides java.lang.Object.toString.

Doc from java.lang.Object.toString.

Returns a string representation of the object.

Returns:String

a string representation of the object.
