Method Detail

equalsback to summary
public boolean equals(Object o)

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.

public static List<XMLStructure> getContent(KeyInfo ki)

A utility function to suppress casting warnings.

Returns:List<XMLStructure>

the content of a KeyInfo Object

getContentback to summary
public List<XMLStructure> getContent()

Implements javax.xml.crypto.dsig.keyinfo.KeyInfo.getContent.

Doc from javax.xml.crypto.dsig.keyinfo.KeyInfo.getContent.

Returns an unmodifiable list containing the key information. Each entry of the list is an XMLStructure.

If there is a public subclass representing the type of XMLStructure, it is returned as an instance of that class (ex: an X509Data element would be returned as an instance of javax.xml.crypto.dsig.keyinfo.X509Data).

public String getId()

Implements javax.xml.crypto.dsig.keyinfo.KeyInfo.getId.

Doc from javax.xml.crypto.dsig.keyinfo.KeyInfo.getId.

Return the optional Id attribute of this KeyInfo, which may be useful for referencing this KeyInfo from other XML structures.

Annotations
@Override
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.
