Method Detail

values

public static TSDataType[] 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 (TSDataType c : TSDataType.values())
    System.out.println(c);

Returns:

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

valueOf

public static TSDataType 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

deserialize

public static TSDataType deserialize(byte type)

give an integer to return a data type.

Parameters:

type - -param to judge enum type

Returns:

-enum type

getType

public byte getType()

getTsDataType

public static TSDataType getTsDataType(byte type)

deserializeFrom

public static TSDataType deserializeFrom(ByteBuffer buffer)

deserializeFrom

Throws:

IOException

getSerializedSize

public static int getSerializedSize()

serializeTo

public void serializeTo(ByteBuffer byteBuffer)

serializeTo

public void serializeTo(DataOutputStream outputStream)
                 throws IOException

Throws:

serializeTo

public void serializeTo(FileOutputStream outputStream)
                 throws IOException

Throws:

IOException

getDataTypeSize

public int getDataTypeSize()

serialize

public byte serialize()

get type byte.

Returns:

byte number

isNumeric

public boolean isNumeric()

numeric datatype judgement.

Returns:

whether it is a numeric datatype

Throws:

UnSupportedDataTypeException - when meets unSupported DataType

isComparable

public boolean isComparable()

comparable datatype judgement.

Returns:

whether it is a comparable datatype

Throws:

UnSupportedDataTypeException - when meets unSupported DataType
