        Overrides:
        removeProperty in class ej.property.registry.SimplePropertyRegistry

      • getProperty

        @Nullable
public java.lang.String getProperty​(java.lang.String key)
        Searches for the property with the specified key in the property lists. If the property is not found in any map of properties, then the method returns null. Different property maps of properties exist. The order in which they are searched in is:
        1. Current application,
        2. Kernel,
        3. Trusted applications,
        4. Other applications.
        In the case a property value is set to null, then it is considered as non-existent in its map and the search goes on, possibly returning a shared-property sharing the same key.
        Specified by:
        getProperty in interface ej.property.PropertyLoader
        Overrides:
        getProperty in class ej.property.registry.SimplePropertyRegistry
        Parameters:
        key - the property key.
        Returns:
        the value of the property list with the specified key value.
