Method Detail

contains

public boolean contains(T position)

Specified by:

contains in class AbstractBounds<T extends RingPosition<T>>

split

public Pair<AbstractBounds<T>,AbstractBounds<T>> split(T position)

Description copied from class: AbstractBounds

Given token T and AbstractBounds ?L,R?, returns Pair(?L,T], (T,R?), where ? means that the same type of AbstractBounds is returned as the original. Put another way, returns a Pair of everything this AbstractBounds contains up to and including the split position, and everything it contains after (not including the split position). The original AbstractBounds must either contain the position T, or T should be equals to the left bound L. If the split would only yield the same AbstractBound, null is returned instead.

Specified by:

split in class AbstractBounds<T extends RingPosition<T>>

inclusiveLeft

public boolean inclusiveLeft()

Specified by:

inclusiveLeft in class AbstractBounds<T extends RingPosition<T>>

inclusiveRight

public boolean inclusiveRight()

Specified by:

inclusiveRight in class AbstractBounds<T extends RingPosition<T>>

unwrap

public java.util.List<? extends AbstractBounds<T>> unwrap()

Specified by:

unwrap in class AbstractBounds<T extends RingPosition<T>>

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getOpeningString

protected java.lang.String getOpeningString()

Specified by:

getOpeningString in class AbstractBounds<T extends RingPosition<T>>

getClosingString

protected java.lang.String getClosingString()

Specified by:

getClosingString in class AbstractBounds<T extends RingPosition<T>>

toRowBounds

public AbstractBounds<RowPosition> toRowBounds()

Description copied from class: AbstractBounds

Transform this abstract bounds to equivalent covering bounds of row positions. If this abstract bounds was already an abstractBounds of row positions, this is a noop.

Specified by:

toRowBounds in class AbstractBounds<T extends RingPosition<T>>

toTokenBounds

public AbstractBounds<Token> toTokenBounds()

Description copied from class: AbstractBounds

Transform this abstract bounds to a token abstract bounds. If this abstract bounds was already an abstractBounds of token, this is a noop, otherwise this use the row position tokens.

Specified by:

toTokenBounds in class AbstractBounds<T extends RingPosition<T>>

withNewRight

public AbstractBounds<T> withNewRight(T newRight)

Specified by:

withNewRight in class AbstractBounds<T extends RingPosition<T>>
