Constructor Detail

BigIntArgument

public BigIntArgument(int type,
                      ArgumentType argumentType,
                      long value)

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).

writeValue

protected void writeValue(java.io.OutputStream outputStream,
                          long value)
                   throws java.io.IOException

Throws:

java.io.IOException

getValueAsLong

public long getValueAsLong()

Description copied from interface: Parameter

The value of the parameter as long.

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

Specified by:

getValueAsLong in interface Parameter

Overrides:

getValueAsLong in class Argument

Returns:

The value as long

copyTo

public void copyTo(ParameterBuffer buffer,
                   Encoding encoding)

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

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

equals

public boolean equals(java.lang.Object other)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class Argument
