Method Detail

values

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

Returns:

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

valueOf

public static ParquetValueDrivers 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

getValueOptionClass

public Class<? extends ValueOption<?>> getValueOptionClass()

Returns the Asakusa type information for this driver.

Returns:

the value option class

getTypeInfo

public org.apache.hadoop.hive.serde2.typeinfo.TypeInfo getTypeInfo()

Returns the Hive type information for this driver.

Returns:

the type information

getType

public parquet.schema.Type getType(String name)

Description copied from interface: ParquetValueDriver

Returns a parquet data type for this driver.

Specified by:

getType in interface ParquetValueDriver

Parameters:

name - the field name

Returns:

the related type

of

public static ParquetValueDriver of(org.apache.hadoop.hive.serde2.typeinfo.TypeInfo typeInfo,
                                    Class<?> valueClass)

Returns a ParquetValueDriver for the specified type.

Parameters:

typeInfo - the Hive type info

valueClass - the ValueOption type

Returns:

the corresponded ParquetValueDriver

find

public static ParquetValueDriver find(org.apache.hadoop.hive.serde2.typeinfo.TypeInfo typeInfo,
                                      Class<?> valueClass)

Returns a ParquetValueDriver for the specified type.

Parameters:

typeInfo - the Hive type info

valueClass - the ValueOption type

Returns:

the corresponded ParquetValueDriver, or null if it is not found
