Method Detail

values

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

Returns:

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

valueOf

public static Type 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

getDataType

@Deprecated
public org.apache.kudu.Common.DataType getDataType()

Deprecated. use getDataType(ColumnTypeAttributes)

Get the data type from the common's pb

Returns:

A DataType

getDataType

public org.apache.kudu.Common.DataType getDataType(ColumnTypeAttributes typeAttributes)

Get the data type from the common's pb

Parameters:

typeAttributes - the additional attributes of the type.

Returns:

A DataType

getName

public String getName()

Get the string representation of this type

Returns:

The type's name

getSize

@Deprecated
public int getSize()

Deprecated. use getSize(ColumnTypeAttributes)

The size of this type on the wire

Returns:

A size

getSize

public int getSize(ColumnTypeAttributes typeAttributes)

The size of this type on the wire

Parameters:

typeAttributes - the additional attributes of the type.

Returns:

A size

toString

public String toString()

Overrides:

toString in class Enum<Type>

getTypeForDataType

public static Type getTypeForDataType(org.apache.kudu.Common.DataType type)

Convert the pb DataType to a Type

Parameters:

type - DataType to convert

Returns:

a matching Type

getTypeForName

public static Type getTypeForName(String name)

Create a Type from its name

Parameters:

name - The DataType name. It accepts Type name (from the getName() method) and ENUM name (from the name() method).

Returns:

a matching Type.

Throws:

IllegalArgumentException - if the provided name doesn't map to any known type.

isFixedSize

public boolean isFixedSize()

Returns:

true if this type has a pre-determined fixed size, false otherwise
