Method Detail

getPropertyValue

public java.lang.String getPropertyValue(java.lang.String propertyName)

Returns the value for a given property, or null if the source does not provide a value for the named property. Implementations of IPropertySource may use delegation to resolve the value (that is, if one property source returns null, it may forward the request to another source).
