Method Details

getModificationCount

long getModificationCount()

Returns the current modification count. Modification count must be strictly increasing.

Returns:

the current change sequence number

ensureCanonical

void ensureCanonical()

Ensures that the internal representation is in a canonical form such that it can be read safely by multiple threads.

getTokenSetter

ScalarSettable getTokenSetter(int index)

Description copied from interface: MutableTokenSequence

Returns a mutator for the given index.

Specified by:

getTokenSetter in interface MutableTokenSequence

Parameters:

index - the position

Returns:

a mutator for the given index.
