a SerializableXid

Method Detail

equalsback to summary
public boolean equals(Object obj)

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
obj:Object

the reference object with which to compare.

Returns:boolean

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

getBranchQualifierback to summary
public byte[] getBranchQualifier()

Implements javax.transaction.xa.Xid.getBranchQualifier.

Doc from javax.transaction.xa.Xid.getBranchQualifier.

Obtain the transaction branch identifier part of XID as an array of bytes.

Returns:byte[]

Global transaction identifier.

getFormatIdback to summary
public int getFormatId()

Implements javax.transaction.xa.Xid.getFormatId.

Doc from javax.transaction.xa.Xid.getFormatId.

Obtain the format identifier part of the XID.

Returns:int

Format identifier. O means the OSI CCR format.

getGlobalTransactionIdback to summary
public byte[] getGlobalTransactionId()

Implements javax.transaction.xa.Xid.getGlobalTransactionId.

Doc from javax.transaction.xa.Xid.getGlobalTransactionId.

Obtain the global transaction identifier part of XID as an array of bytes.

Returns:byte[]

Global transaction identifier.

hashCodeback to summary
public int hashCode()

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.

toStringback to summary
public String toString()

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.
