Examples of org.openquark.cal.runtime.ExecutionContextProperties

org.openquark.cal.runtime.ExecutionContextProperties
This class encapsulates an immutable map of key-value pairs which are exposed in CAL as system properties. Only strings can be used as keys.
There are a number of keys whose values are constrained to be of a particular type, e.g. the value for the "cal.locale" property must be of type {@link java.util.Locale}. For these special keys, dedicated methods are available for accessing their values. These properties are known as system properties.
For other keys, their corresponding values can be objects of any type. It is up to the client code to coordinate the setting of the property on the Java side with the retrieval on the CAL side.
Note that instances of this class are immutable. In fact, the only way to build an instance is through the {@link ExecutionContextProperties.Builder} class, which contains methods for adding key-value pairs,and for finally building an instance of this class. @author Joseph Wong
