Method Detail

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getType

public ArrayTable.RepresentationType getType()

Description copied from interface: ArrayTable.Representation

Returns the representation type.

Specified by:

getType in interface ArrayTable.Representation

freeze

public java.lang.Object freeze(ColumnLoader.ValueSet valueSet,
                               int[] sources)

Description copied from interface: ArrayTable.Representation

Converts a value set into a compact representation. If sources is not null, permutes.

Specified by:

freeze in interface ArrayTable.Representation

permute

public java.lang.Object permute(java.lang.Object dataSet,
                                int[] sources)

Description copied from interface: ArrayTable.Representation

Creates a data set that is the same as a given data set but re-ordered.

Specified by:

permute in interface ArrayTable.Representation

getObject

public java.lang.Object getObject(java.lang.Object dataSet,
                                  int ordinal)

Specified by:

getObject in interface ArrayTable.Representation

getInt

public int getInt(java.lang.Object dataSet,
                  int ordinal)

Specified by:

getInt in interface ArrayTable.Representation

size

public int size(java.lang.Object dataSet)

Description copied from interface: ArrayTable.Representation

Returns the number of elements in a data set. (Some representations return the capacity, which may be slightly larger than the actual size.)

Specified by:

size in interface ArrayTable.Representation

toString

public java.lang.String toString(java.lang.Object dataSet)

Description copied from interface: ArrayTable.Representation

Converts a data set to a string.

Specified by:

toString in interface ArrayTable.Representation
