describe

@CheckForNull
public static String describe(CredentialsMatcher matcher)

Attempts to describe the supplied CredentialsMatcher in terms of a Credentials Query Language. The basic form of the query language should follow Java expression syntax assuming that there is one variable in scope, namely the credential. The Java Bean style properties will be exposed as variables in the context. Example: (instanceof com.cloudbees.plugins.credentials.common.UsernameCredentials) && !(username == "bob") will match all instances of UsernameCredentials with UsernameCredentials.getUsername() not equal to bob. See also CQLParser.

Parameters:

matcher - the CredentialsMatcher to describe.

Returns:

the CQL description or null if the CredentialsMatcher cannot be mapped to CQL.

Since:

2.1.0

parse

public static CredentialsMatcher parse(String cql)

Attempts to parse a Credentials Query Language expression and construct the corresponding matcher.

Parameters:

cql - the Credentials Query Language expression to parse.

Returns:

a CredentialsMatcher for this expression.

CQLSyntaxException - if the expression could not be parsed.

Since:

2.1.0
