Enum Constant Detail

RSTREAM_ONLY

public static final SelectClauseStreamSelectorEnum RSTREAM_ONLY

Indicates selection of the remove stream only.

ISTREAM_ONLY

public static final SelectClauseStreamSelectorEnum ISTREAM_ONLY

Indicates selection of the insert stream only.

RSTREAM_ISTREAM_BOTH

public static final SelectClauseStreamSelectorEnum RSTREAM_ISTREAM_BOTH

Indicates selection of both the insert and the remove stream.

Method Detail

values

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

Returns:

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

valueOf

public static SelectClauseStreamSelectorEnum valueOf(java.lang.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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

isSelectsRStream

public boolean isSelectsRStream()

isSelectsIStream

public boolean isSelectsIStream()

mapFromSODA

public static SelectClauseStreamSelectorEnum mapFromSODA(StreamSelector selector)

Maps the SODA-selector to the internal representation

Parameters:

selector - is the SODA-selector to map

Returns:

internal stream selector

mapFromSODA

public static StreamSelector mapFromSODA(SelectClauseStreamSelectorEnum selector)

Maps the internal stream selector to the SODA-representation

Parameters:

selector - is the internal selector to map

Returns:

SODA stream selector
