Method Detail

toBlockingMode

public static final BlockingMode toBlockingMode(java.lang.String name)

A utility method to convert a string name to a BlockingMode

Parameters:

name -

Returns:

The associated BlockingMode constant if name is valid, null otherwise

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

readResolve

java.lang.Object readResolve()
                      throws java.io.ObjectStreamException

Overriden to return the indentity instance of BlockingMode based on the stream type int value. This ensures that BlockingMode enums can be compared using ==.

Returns:

The BlockingMode instance for the XXX_TYPE int.

Throws:

java.io.ObjectStreamException
