Method Detail

values

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

Returns:

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

valueOf

public static DBType 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

getType

public String getType()

Get string representation of the database. This constant is supposed to be used as internal code name.

Returns:

The code name

getDisplayName

public String getDisplayName()

Display name of the database

getMaxTableNameLength

public int getMaxTableNameLength()

getMaxColumnNameLength

public int getMaxColumnNameLength()

getMaxIndexNameLength

public int getMaxIndexNameLength()

getPreferedFetchSize

public int getPreferedFetchSize()

Gets optimal fetch sizes for this DB type.
