Method Detail

setProperty

@Nullable
public java.lang.String setProperty(java.lang.String key,
                                               java.lang.String value)

Specified by:

setProperty in interface ej.property.PropertyRegistry

Overrides:

setProperty in class ej.property.registry.SimplePropertyRegistry

removeProperty

@Nullable
public java.lang.String removeProperty(java.lang.String key)

Specified by:

removeProperty in interface ej.property.PropertyRegistry

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.

stateChanged

public void stateChanged(@Nullable
                         ej.kf.Feature feature,
                         @Nullable
                         ej.kf.Feature.State previousState)
