              throws IOException

Creates a properties map from the stream.

Parameters:

is - stream to load properties from.

Throws:

IOException - if I/O error occurs

Parameters:

key - property name

value - property value

Returns:

value associated with specified key, or null if there was no mapping for key.

Specified by:

entrySet in interface Map<String,Object>

equals

public boolean equals(Object o)

Specified by:

equals in interface Map<String,Object>

Overrides:

equals in class Object

hashCode
