java.lang.Object java.security.CodeSource
public class CodeSource
This class extends the concept of a codebase to encapsulate not only the location (URL) but also the certificate chains that were used to verify signed code originating from that location.
Constructor Summary | |
---|---|
CodeSource(URL url,
Certificate[] certs)
Constructs a CodeSource and associates it with the specified location and set of certificates. |
|
CodeSource(URL url,
CodeSigner[] signers)
Constructs a CodeSource and associates it with the specified location and set of code signers. |
Method Summary | |
---|---|
boolean |
equals(Object obj)
Tests for equality between the specified object and this object. |
Certificate[] |
getCertificates()
Returns the certificates associated with this CodeSource. |
CodeSigner[] |
getCodeSigners()
Returns the code signers associated with this CodeSource. |
URL |
getLocation()
Returns the location associated with this CodeSource. |
int |
hashCode()
Returns the hash code value for this object. |
boolean |
implies(CodeSource codesource)
Returns true if this CodeSource object "implies" the specified CodeSource. |
String |
toString()
Returns a string describing this CodeSource, telling its URL and certificates. |

- the location (URL).certs
- the certificate(s). It may be null. The contents of the
array are copied to protect against subsequent modification.public CodeSource(URL url, CodeSigner[] signers)

- the location (URL).signers
- the code signers. It may be null. The contents of the

public final Certificate[] getCertificates()
If this CodeSource object was created using the
CodeSource(URL url, CodeSigner[] signers)
constructor then its certificate chains are extracted and used to
create an array of Certificate objects. Each signer certificate is
followed by its supporting certificate chain (which may be empty).
Each signer certificate and its supporting certificate chain is ordered
bottom-to-top (i.e., with the signer certificate first and the (root)
certificate authority last).
public final CodeSigner[] getCodeSigners()
If this CodeSource object was created using the
CodeSource(URL url, Certificate[] certs)
constructor then its certificate chains are extracted and used to
create an array of CodeSigner objects. Note that only X.509 certificates
are examined - all other certificate types are ignored.
public boolean implies(CodeSource codesource)
More specifically, this method makes the following checks, in order. If any fail, it returns false. If they all succeed, it returns true.
For example, the codesource objects with the following locations and null certificates all imply the codesource with the location "http://java.sun.com/classes/foo.jar" and null certificates:
http: http://*.sun.com/classes/* http://java.sun.com/classes/- http://java.sun.com/classes/foo.jarNote that if this CodeSource has a null location and a null certificate chain, then it implies every other CodeSource.
codesource
- CodeSource to compare against.
