public Class JtaTransactionAnnotationParser

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.

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.

Annotations

@Override

Overrides default org.springframework.transaction.annotation.TransactionAnnotationParser.isCandidateClass.

Doc from org.springframework.transaction.annotation.TransactionAnnotationParser.isCandidateClass.

Determine whether the given class is a candidate for transaction attributes in the annotation format of this TransactionAnnotationParser.

If this method returns false, the methods on the given class will not get traversed for #parseTransactionAnnotation introspection. Returning false is therefore an optimization for non-affected classes, whereas true simply means that the class needs to get fully introspected for each method on the given class individually.

Parameters

targetClass:Class<?>

the class to introspect

Returns:boolean

false if the class is known to have no transaction annotations at class or method level; true otherwise. The default implementation returns true, leading to regular introspection.

Annotations

@Override

Implements org.springframework.transaction.annotation.TransactionAnnotationParser.parseTransactionAnnotation.

Doc from org.springframework.transaction.annotation.TransactionAnnotationParser.parseTransactionAnnotation.

Parse the transaction attribute for the given method or class, based on an annotation type understood by this parser.

This essentially parses a known transaction annotation into Spring's metadata attribute class. Returns null if the method/class is not transactional.

Parameters

element:AnnotatedElement

the annotated method or class

Returns:TransactionAttribute

the configured transaction attribute, or null if none found
