Constructor Detail

AbstractNode

public AbstractNode()

Method Detail

isFlagSet

protected final boolean isFlagSet(AbstractNode.NodeFlags flag)

Tests whether a flag is set.

Parameters:

flag - flag to test

Returns:

true if set, false otherwise.

setFlag

protected final void setFlag(AbstractNode.NodeFlags flag,
                             boolean value)

Utility method for setting or unsetting a flag. If status is true, the NodeFlag specified is added to the flags encoded short. If status is false, the NodeFlag is removed from the encoded short.

Parameters:

flag - flag to set or unset

value - true to set the flag, false to unset the flag.

setFlag

protected final void setFlag(AbstractNode.NodeFlags flag)

Unility method that sets the value of the given flag to true.

Parameters:

flag - flag to set

unsetFlag

protected final void unsetFlag(AbstractNode.NodeFlags flag)

Utility method that sets the value of the flag to false.

Parameters:

flag - flag to unset
