Constructor Detail

BufferedRows.DoubleNodeRow

protected BufferedRows.DoubleNodeRow(CachedNode node1,
                          CachedNode node2,
                          float score1,

Method Detail

width

public int width()

Description copied from interface: NodeSequence.RowAccessor

Get the number of nodes in each row.

Specified by:

width in interface NodeSequence.RowAccessor

Returns:

the width of each row; always positive

getNode

public CachedNode getNode()

Description copied from interface: NodeSequence.RowAccessor

Get the first node in the current row. This is a convenience method that is equivalent to getNode(0).

Specified by:

getNode in interface NodeSequence.RowAccessor

Returns:

the first node in the current row; may be null if there is no node at the first position in this row

getNode

public CachedNode getNode(int index)

Description copied from interface: NodeSequence.RowAccessor

Get the node at the specified index in the current row.

Specified by:

getNode in interface NodeSequence.RowAccessor

Parameters:

index - the 0-based index for the node in the row; must be less than NodeSequence.RowAccessor.width().

Returns:

the specified node in the current row; may be null if there is no node at the valid index in this row

getScore

public float getScore()

Description copied from interface: NodeSequence.RowAccessor

Get the score for the first node in the current row. This is a convenience method that is equivalent to getScore(0).

Specified by:

getScore in interface NodeSequence.RowAccessor

Returns:

the score for the first node in the current row; always 0.0f if there is no corresponding node at the valid index in this row

getScore

public float getScore(int index)

Description copied from interface: NodeSequence.RowAccessor

Get the score for the specified node in the current row.

Specified by:

getScore in interface NodeSequence.RowAccessor

Parameters:

index - the 0-based index for the node in the row; must be less than NodeSequence.RowAccessor.width().

Returns:

the score for the specified node in the current row; always 0.0f if there is no corresponding node at the valid index in this row

toString

public String toString()

Overrides:

toString in class Object
