StringArgument

public StringArgument(int type,
                      ArgumentType argumentType,
                      java.lang.String value,
                      Encoding encoding)

Method Detail

writeTo

public void writeTo(java.io.OutputStream outputStream)
             throws java.io.IOException

Description copied from class: Argument

Writes the arguments to the supplied OutputStream in the XDR format of the type.

Specified by:

writeTo in class Argument

Parameters:

outputStream - OutputStream

Throws:

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

getLength

public int getLength()

Specified by:

getLength in class Argument

Returns:

Total length of the buffer item when written to the OutputStream by Argument.writeTo(java.io.OutputStream). This includes the item, the value and other items contributing to the total length (eg the length of the value).

getValueAsString

public java.lang.String getValueAsString()

Description copied from interface: Parameter

The value of the parameter as String.

The implementation may throw a RuntimeException if the parameter isn't a string (or shouldn't be used as a string).

Specified by:

getValueAsString in interface Parameter

Overrides:

getValueAsString in class Argument

Returns:

The value as string

getValueAsInt

public int getValueAsInt()

Description copied from interface: Parameter

The value of the parameter as int.

The implementation may throw a RuntimeException if the parameter isn't an int (or shouldn't be used as an int).

Specified by:

getValueAsInt in interface Parameter

Overrides:

getValueAsInt in class Argument

Returns:

The value as int

copyTo

public void copyTo(ParameterBuffer buffer,
                   Encoding stringEncoding)

Description copied from interface: Parameter

Copies this argument into the supplied buffer, uses the supplied Encoding for string arguments.

An instance of Parameter should know how to copy itself into another buffer (eg an instance of StringArgument would know to call ParameterBuffer.addArgument(int, String, Encoding)).

The parameter does not need to check if it is the right type of destination buffer (if someone tries to add a TPB argument to a DPB he is free to try that).

Parameters:

buffer - ParameterBuffer instance

stringEncoding - Encoding to use for string properties. A value of null can be used to signal that the original encoding should be used.

hashCode

public int hashCode()

Overrides:

hashCode in class Argument

equals

public boolean equals(java.lang.Object other)

Overrides:

equals in class java.lang.Object
