Enum ArgumentType

java.lang.Object

java.lang.Enum<ArgumentType>

org.firebirdsql.gds.impl.argument.ArgumentType

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<ArgumentType>

public enum ArgumentType
extends java.lang.Enum<ArgumentType>

Argument metadata type.

Indicates how the argument should be represented in the parameter buffer. Primary use case is to distinguish between 3.0 "wide" arguments, and 2.5 and earlier "traditional" arguments.

Since:

3.0

Method Detail

values

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

Returns:

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

valueOf

public static ArgumentType 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

getLengthSize

public abstract int getLengthSize()

Returns:

The size of the encoded length; 0 (zero) if the length is not part of the message.

getMaxLength

public abstract int getMaxLength()

Returns:

The maximum length of encoded data.

writeLength

public abstract void writeLength(int length,
                                 java.io.OutputStream outputStream)
                          throws java.io.IOException

Writes the length into the stream in the proper format.

For arguments without encoded length, this method should not do anything.

Parameters:

length - length to encode

outputStream - Output stream

Throws:

java.io.IOException - For errors writing to the stream
