Returns:

The number of properties of this context; 0 if this context has no property.

Here is an example of context merging with the specified context 'c2' has two properties 'p1' and 'p2=value2' and this context 'c1' has 'p2=value1' and 'p3'.

Then if 'updateKnownProperties' is 'true' then the context 'c1' will have the following properties: 'p1', 'p2=value2', 'p3'

Then if 'updateKnownProperties' is 'false' then the context 'c1': 'p1', 'p2=value1', 'p3'

Parameters:

context - The context which must be merged with this context. Null 'context' supported.

updateKnownProperties - true if the properties which already exists in this context must be updated or not

duplicate

public OperationExecutionContext duplicate()

Returns a copy of this context, containing a copy of each of its properties.

Returns:

A copy of this context
