public class StorageType
extends Type

The StorageType class represents the various basic types that are native to Java. User defined types are ultimately defined in terms of storage types, since these are the units that are written and read from disk or other sources of raw data.

Method Detail

typeStringtoInt

public static int typeStringtoInt(java.lang.String type)

Returns a valid type constant if the String argument is a valid type string. Otherwise, returns 0.

intToTypeString

public static final java.lang.String intToTypeString(int type)

returns a String of the name of the type indicated by the argument.

name

public static java.lang.String name(int type)

returns a String of the name of the type indicated by the argument.

isStorageType

public static final boolean isStorageType(int type)

Returns true if the argument is a valid StorageType value, false otherwise.

isSimpleStorageType

public static final boolean isSimpleStorageType(int type)

Returns true if the argument is a valid StorageType value, except for StorageType.Record. For this value and any non-StorageType value this method returns false.

toString

public java.lang.String toString()

Return this StorageType represented as a nicely formatted String.

Overrides:

toString in class Type

getNumStorageTypes

public static final int getNumStorageTypes()

Return the number of distinct StorageTypes.

byteSize

public static int byteSize(int type)

Return the length in bytes of the "basic" StorageTypes. The length of StorageType.Record and all other types is returned as 0.

main

public static void main(java.lang.String[] args)
