public LeafNode.IntArrayLeafNode(int[] data)

Method Detail

getAllData

public Object getAllData()

Get all data in this leaf

Specified by:

getAllData in class LeafNode

Returns:

the int array contained in this leaf

getIntData

public int[] getIntData()

fillData

protected void fillData(Object target,
            int pos,
            int len)

Description copied from class: LeafNode

Write this node's data into the target object at pos, making sure that exactly len data are written. The type of data written depends on the type of nodes; for example, when IntArrayLeafNodes are used, target would be an int[].

Specified by:

fillData in class LeafNode

Parameters:

target - the object to write to, usually an array.

pos - the position in the target at which to start writing

len - the amount of data items to write, usually equals getNumberOfData().

getNumberOfData

public int getNumberOfData()

Description copied from class: LeafNode

Count all the data available at and below this node. The meaning of this depends on the type of nodes; for example, when IntArrayLeafNodes are used, it is the total number of ints that are saved in all leaf nodes below the current node.

Specified by:

getNumberOfData in class LeafNode

Returns:

an int counting the data below the current node, or -1 if such a concept is not meaningful.

isEmpty

public boolean isEmpty()

Description copied from class: LeafNode

Indicate whether the leaf node has no meaningful data.

Specified by:

isEmpty in class LeafNode

Returns:

whether the node is empty or not

getLeafNodeType

public LeafNode.LeafType getLeafNodeType()

Description copied from class: LeafNode

The type of this leaf node.

Specified by:

getLeafNodeType in class LeafNode

Returns:

the type of the leaf node

toString

public String toString()

Overrides:

toString in class LeafNode
