Method Detail

values

public static PropertyType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (PropertyType c : PropertyType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static PropertyType valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

intValue

public int intValue()

Returns an int value representing the type.

Returns:

The int value for this property type

byteValue

public byte byteValue()

Returns a byte value representing the type. As long as there are < 128 PropertyTypes, this should be equal to intValue(). When this statement no longer holds, this method should be removed.

Returns:

The byte value for this property type

getValue

public abstract Object getValue(PropertyBlock block,
                                PropertyStore store)

newPropertyData

public abstract PropertyData newPropertyData(PropertyBlock block,
                                             long propertyId,
                                             Object extractedValue)

getPropertyType

public static PropertyType getPropertyType(long propBlock,
                                           boolean nullOnIllegal)

getPayloadSize

public static int getPayloadSize()

getPayloadSizeLongs

public static int getPayloadSizeLongs()

setPayloadSize

public static void setPayloadSize(int newPayloadSize)

calculateNumberOfBlocksUsed

public int calculateNumberOfBlocksUsed(long firstBlock)
