public class LBR.Indexes
extends java.lang.Object
implements java.io.Serializable

Class for handling instances and the associated attributes.

Enables a set of indexes to a given dataset to be created and used with an algorithm. This reduces the memory overheads and time required when manipulating and referencing Instances and their Attributes.

m_AttIndexes: the array attribute indexes
m_ClassIndex: the Class Index for the data set
m_InstIndexes: the array instance indexes
m_NumAttsSet: the number of attributes "in use" or set to a the original value (true or false)
m_NumInstsSet: the number of instances "in use" or set to a the original value (true or false)
m_NumSeqAttsSet: the number of sequential attributes "in use" or set to a the original value (true or false)
m_NumSeqInstsSet: the number of sequential instances "in use" or set to a the original value (true or false)
m_SequentialAttIndexes: an array of attribute indexes that are set to either true or false
m_SequentialInstIndexes: the array of instance indexes that are set to a either true or false

setInstanceIndex(int, boolean): Changes the boolean value at the specified index in the InstIndexes array
setInsts(int[], boolean): Changes the boolean value at the specified index in the InstIndexes array
setSequentialAttIndex(boolean): A Sequential Attribute index is all those Attributes that are set to the specified value placed in a sequential array.
setSequentialDataset(boolean): Sets both the Instance and Attribute indexes to a specified value
setSequentialInstanceIndex(boolean): A Sequential Instance index is all those Instances that are set to the specified value placed in a sequential array.
