Enum SQLPagingStrategy

java.lang.Object
  java.lang.Enum<SQLPagingStrategy>
      com.smartgwt.client.types.SQLPagingStrategy

All Implemented Interfaces:

ValueEnum, Serializable, Comparable<SQLPagingStrategy>

public enum SQLPagingStrategy
extends Enum<SQLPagingStrategy>
implements ValueEnum

The technique Smart GWT Server's SQL DataSource should use to select a "page" of data from a table.

Enum Constant Summary

DROPONSERVER
Implement the paging behavior by fetching the entire resultset from the database and dropping any unnecessary rows on the server before returning the data to the client.

JDBCSCROLL
Implement the paging behavior by use of the absolute method of the JDBC ResultSet.

NONE
No paging behavior: we always return the entire resultset to the client.

SQLLIMIT
Specify the paging directly in the SQL query we generate.

Method Summary

String	getValue()
static SQLPagingStrategy	valueOf(String name) Returns the enum constant of this type with the specified name.
static SQLPagingStrategy[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

SQLLIMIT

public static final SQLPagingStrategy SQLLIMIT

Specify the paging directly in the SQL query we generate. The way this is done varies considerably from database to database: with some it is a straightforward built-in facility while others require arcane tricks. This is the most efficient method.

JDBCSCROLL

public static final SQLPagingStrategy JDBCSCROLL

Implement the paging behavior by use of the absolute method of the JDBC ResultSet.

DROPONSERVER

public static final SQLPagingStrategy DROPONSERVER

Implement the paging behavior by fetching the entire resultset from the database and dropping any unnecessary rows on the server before returning the data to the client.

NONE

public static final SQLPagingStrategy NONE

No paging behavior: we always return the entire resultset to the client.

Method Detail

values

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

Returns:

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

valueOf

public static SQLPagingStrategy 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

getValue

public String getValue()

Specified by:

getValue in interface ValueEnum
