DESCRIBE

public static final FlatFileParams.SchemaType DESCRIBE

Schema name for a special type of query that returns a one column result with space separated columns sizes

SAMPLE

public static final FlatFileParams.SchemaType SAMPLE

Schema name for a special type of query that returns parsed text columns (including headers) as they appear in a text file. Sample queries are limited to a specified number of rows

QUERY

public static final FlatFileParams.SchemaType QUERY

Schema name for a typical query, in which columns are casted to typed data

QUERY_TEXT

public static final FlatFileParams.SchemaType QUERY_TEXT

Schema name for a query in which columns are returned as text. Similar to sample, except headers are not returned, and there is no limit on the amount of rows returned.

Method Detail

values

public static final FlatFileParams.SchemaType[] values()

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

for(FlatFileParams.SchemaType c : FlatFileParams.SchemaType.values())
        System.out.println(c);

Returns:

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

valueOf

public static FlatFileParams.SchemaType 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
