All Implemented Interfaces:

VarMeta

Direct Known Subclasses:

abstract class AbstractVarMeta
extends MPPComponent
implements VarMeta

This class reads in the data from a VarMeta block. This block contains meta data about variable length data items stored in a Var2Data block. The meta data allows the size of the Var2Data block to be determined, along with the number of data items it contains, identifiers for each item, and finally the offset of each item within the block.

java.util.Set<java.lang.Integer>	getTypes(java.lang.Integer id) Retrieves a set containing the types defined in the var data for a given ID.
java.lang.Integer[]	getUniqueIdentifierArray() This method returns an array containing all of the unique identifiers for which data has been stored in the Var2Data block.
java.util.Set<java.lang.Integer>	getUniqueIdentifierSet() This method returns an set containing all of the unique identifiers for which data has been stored in the Var2Data block.
java.lang.String	toString() This method dumps the contents of this VarMeta block as a String.

Method Detail

getItemCount

public int getItemCount()

This method retrieves the number of items in the Var2Data block.

Specified by:

getItemCount in interface VarMeta

Returns:

number of items

getDataSize

public int getDataSize()

This method retrieves the size of the Var2Data block.

Specified by:

getDataSize in interface VarMeta

Returns:

data size

getUniqueIdentifierArray

public java.lang.Integer[] getUniqueIdentifierArray()

This method returns an array containing all of the unique identifiers for which data has been stored in the Var2Data block.

Specified by:

getUniqueIdentifierArray in interface VarMeta

Returns:

array of unique identifiers

getUniqueIdentifierSet

public java.util.Set<java.lang.Integer> getUniqueIdentifierSet()

This method returns an set containing all of the unique identifiers for which data has been stored in the Var2Data block.

Specified by:

getUniqueIdentifierSet in interface VarMeta

Returns:

set of unique identifiers

getOffset

public java.lang.Integer getOffset(java.lang.Integer id,
                                   java.lang.Integer type)

This method retrieves the offset of a given entry in the Var2Data block. Each entry can be uniquely located by the identifier of the object to which the data belongs, and the type of the data.

Specified by:

getOffset in interface VarMeta

Parameters:

id - unique identifier of an entity

type - data type identifier

id - unique ID

Returns:

set of types

toString

public java.lang.String toString()

This method dumps the contents of this VarMeta block as a String. Note that this facility is provided as a debugging aid.

Overrides:

toString in class java.lang.Object

Returns:

formatted contents of this block
