Provider Class

Definition

This class represents a "provider" for the Java Security API, where a provider implements some or all parts of Java Security.

[Android.Runtime.Register("java/security/Provider", DoNotGenerateAcw=true)]
public abstract class Provider : Java.Util.Properties
[<Android.Runtime.Register("java/security/Provider", DoNotGenerateAcw=true)>]

Remarks

This class represents a "provider" for the Java Security API, where a provider implements some or all parts of Java Security. Services that a provider may implement include:

<ul>

<li>Algorithms (such as DSA, RSA, MD5 or SHA-1).

<li>Key generation, conversion, and management facilities (such as for algorithm-specific keys).

</ul>

Each provider has a name and a version number, and is configured in each runtime it is installed in.

See The Provider Class in the "Java Cryptography Architecture API Specification &amp; Reference" for information about how a particular type of provider, the cryptographic service provider, works and is installed. However, please note that a provider can be used to implement any security service in Java that uses a pluggable architecture with a choice of implementations that fit underneath.

Some provider implementations may encounter unrecoverable internal errors during their operation, for example a failure to communicate with a security token. A ProviderException should be used to indicate such errors.

The service type Provider is reserved for use by the security framework. Services of this type cannot be added, removed, or modified by applications. The following attributes are automatically placed in each Provider object: <table cellspacing=4> <caption><b>Attributes Automatically Placed in a Provider Object</b></caption> <tr><th>Name</th><th>Value</th> <tr><td>Provider.id name</td> <td>String.valueOf(provider.getName())</td> <tr><td>Provider.id version</td> <td>String.valueOf(provider.getVersion())</td> <tr><td>Provider.id info</td> <td>String.valueOf(provider.getInfo())</td> <tr><td>Provider.id className</td> <td>provider.getClass().getName()</td> </table>

(Inherited from Object)
Compute(Object, IBiFunction)

Attempts to compute a mapping for the specified key and its current mapped value (or null if there is no current mapping).

ComputeIfAbsent(Object, IFunction)

If the specified key is not already associated with a value (or is mapped to null), attempts to compute its value using the given mapping function and enters it into this map unless null.

ComputeIfPresent(Object, IBiFunction)

If the value for the specified key is present and non-null, attempts to compute a new mapping given the key and its current mapped value.

Dispose() (Inherited from Object)
Dispose(Boolean) (Inherited from Object)
Equals(Object)

Indicates whether some other object is "equal to" this one.

(Inherited from Object)
ForEach(IBiConsumer)

Added in 1.

GetHashCode()

Returns a hash code value for the object.

(Inherited from Object)
GetOrDefault(Object, Object)

Added in 1.

GetProperty(String, String)

Searches for the property with the specified key in this property list.

(Inherited from Properties)
GetProperty(String)

Searches for the property with the specified key in this property list.

(Inherited from Properties)
GetService(String, String)

Get the service describing this Provider's implementation of the specified type of this algorithm or alias.

JavaFinalize()

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.

(Inherited from Object)
List(PrintStream)

Prints this property list out to the specified output stream.

(Inherited from Properties)
List(PrintWriter)

Prints this property list out to the specified output stream.

(Inherited from Properties)
Load(Reader)

Reads a property list (key and element pairs) from the input character stream in a simple line-oriented format.

(Inherited from Properties)
Load(Stream)

Reads a property list (key and element pairs) from the input byte stream.

(Inherited from Properties)
LoadFromXML(Stream)

Loads all of the properties represented by the XML document on the specified input stream into this properties table.

(Inherited from Properties)
Merge(Object, Object, IBiFunction)

If the specified key is not already associated with a value or is associated with null, associates it with the given value.

Notify()

Wakes up a single thread that is waiting on this object's monitor.

(Inherited from Object)
NotifyAll()

Wakes up all threads that are waiting on this object's monitor.

(Inherited from Object)
PropertyNames()

Returns an enumeration of all the keys in this property list, including distinct keys in the default property list if a key of the same name has not already been found from the main properties list.

(Inherited from Properties)
Put(Object, Object)

Sets the key property to have the specified value.

PutAll(IDictionary<Object,Object>)

Copies all of the mappings from the specified Map to this provider.

PutIfAbsent(Object, Object)

If the specified key is not already associated with a value (or is mapped to null) associates it with the given value and returns null, else returns the current value.

PutService(Provider+Service)

Add a service.

RemoveService(Provider+Service)

Remove a service previously added using #putService putService().
