Equality of the property value is determined based on the script accessor key and parsing options.
| public | For Externalizable. |
| public boolean | Indicates whether some other object is "equal to" this one. |
| public ScriptAccessProvider | Gets the script language access provider which can be used to operate on the associated script. |
| public ScriptParsingOptions | Gets the parsing options to be used when parsing the associated script. |
| public Object | Gets the script accessor key of the access provider. |
| public int | hashCode() Returns a hash code value for the object. |
| public void | The object implements the readExternal method to restore its
contents by calling the methods of DataInput for primitive
types and readObject for objects, strings and arrays. |
| public void | The object implements the writeExternal method to save its contents
by calling the methods of DataOutput for its primitive values or
calling the writeObject method of ObjectOutput for objects, strings,
and arrays. |
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 returntrue. - It is symmetric: for any non-null reference values
xandy,x.equals(y)should returntrueif and only ify.equals(x)returnstrue. - It is transitive: for any non-null reference values
x,y, andz, ifx.equals(y)returnstrueandy.equals(z)returnstrue, thenx.equals(z)should returntrue. - It is consistent: for any non-null reference values
xandy, multiple invocations ofx.equals(y)consistently returntrueor consistently returnfalse, provided no information used inequalscomparisons on the objects is modified. - For any non-null reference value
x,x.equals(null)should returnfalse.
The equals method for class Object implements the most discriminating possible equivalence
relation on objects; that is, for any non-null reference values x and y, this method returns
true if and only if x and y refer to the same object (x == y has the value
true).
Note that it is generally necessary to override the hashCode method whenever this method is overridden,
so as to maintain the general contract for the hashCode method, which states that equal objects must have
equal hash codes.
true if this object is the same as the obj argument; false otherwise.Note: This is a transient property, meaning that it won't be persisted between serialization and deserialization of this object. This is usually not an issue, as tasks should operate on the instance which was evaluated during build execution.
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
hashCodemethod must consistently return the same integer, provided no information used inequalscomparisons 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(Object)method, then calling thehashCodemethod 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
Object.equals(
Object) method, then calling thehashCodemethod 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.
As much as is reasonably practical, the hashCode method defined by class Object does return distinct
integers for distinct objects. (This is typically implemented by converting the internal address of the object
into an integer, but this implementation technique is not required by the Java™ programming language.)
