Class SyspropsMapWrapper

  • All Implemented Interfaces:
    java.util.Map<java.lang.String,​java.lang.Object>
    public final class SyspropsMapWrapper
extends java.lang.Object
implements java.util.Map<java.lang.String,​java.lang.Object>
    A wrapper that exposes a read-only Map access to the system properties. Any attempt to modify it will throw UnsupportedOperationException. The mapper uses the SYSPROPS_MAPPED_PREFIX to filter and access' only these properties, ignoring all others
