 package org.osgi.framework;

Package private class used by permissions for filter matching on signer key during filter expression evaluation in the permission implies method.

Version:
$Id: 94eea19050b84907f1257d7a12ebf8ab404f4473 $
Immutable:
 
 final class SignerProperty {
 	private final Bundle	bundle;
 	private final String	pattern;

String constructor used by the filter matching algorithm to construct a SignerProperty from the attribute value in a filter expression.

Parameters:
pattern Attribute value in the filter expression.
 
 	public SignerProperty(String pattern) {
 		this. = pattern;
 		this. = null;
 	}

Used by the permission implies method to build the properties for a filter match.

Parameters:
bundle The bundle whose signers are to be matched.
 
 	SignerProperty(Bundle bundle) {
 		this. = bundle;
 		this. = null;
 	}

Used by the filter matching algorithm. This methods does NOT satisfy the normal equals contract. Since the class is only used in filter expression evaluations, it only needs to support comparing an instance created with a Bundle to an instance created with a pattern string from the filter expression.

Parameters:
o SignerProperty to compare against.
Returns:
true if the DN name chain matches the pattern.
 
 	public boolean equals(Object o) {
 		if (!(o instanceof SignerProperty))
 			return false;
 		SignerProperty other = (SignerPropertyo;
 		Bundle matchBundle =  != null ?  : other.bundle;
 		String matchPattern =  != null ? other.pattern : ;
 		for (List<X509CertificatesignerCerts : signers.values()) {
 			List<StringdnChain = new ArrayList<String>(signerCerts.size());
 			for (X509Certificate signerCert : signerCerts) {
 				dnChain.add(signerCert.getSubjectDN().getName());
 			}
 			try {
 				if (FrameworkUtil.matchDistinguishedNameChain(matchPatterndnChain)) {
 					return true;
 				}
 			} catch (IllegalArgumentException e) {
 				continue// bad pattern
 			}
 		}
 		return false;
 	}

Since the equals method does not obey the general equals contract, this method cannot generate hash codes which obey the equals contract.
 
 	public int hashCode() {
 		return 31;
 	}

Check if the bundle is signed.

Returns:
true if constructed with a bundle that is signed.
	boolean isBundleSigned() {
		if ( == null) {
			return false;
		}
		return !signers.isEmpty();
	}
