Field Detail

m_argv

private Map m_argv

This is the (new) alternative explicit argument vector. The reason for using a map is that I cannot random access an ArrayList.

Constructor Detail

ArgVector

public ArgVector()

Default c'tor: Construct a hollow shell and allow further information to be added later.

ArgVector

public ArgVector(String executable)

Constructs an applications without arguments.

Parameters:

executable - is the name of the application.

Method Detail

getValue

public String getValue()

Returns the full argument vector as one single string.

Specified by:

getValue in class Arguments

Returns:

a single string joining all arguments with a single space.

See Also:

setValue(int,String)

setValue

public void setValue(int position,
            String entry)

Sets the argument vector at the specified location.

Parameters:

position - is the position at which to set the entry.

entry - is the argument vector position Setting null is a noop.

toXML

public String toXML(String indent)

Dumps the state of the current element as XML output. This function can return the necessary data more efficiently, thus overwriting the inherited method.

Parameters:

indent - is a String of spaces used for pretty printing. The initial amount of spaces should be an empty string. The parameter is used internally for the recursive traversal.

Returns:

a String which contains the state of the current class and its siblings using XML. Note that these strings might become large.

toXML

public void toXML(Writer stream,
         String indent,
         String namespace)
           throws IOException

Dump the state of the current element as XML output. This function traverses all sibling classes as necessary, and converts the data into pretty-printed XML output. The stream interface should be able to handle large output efficiently.

Specified by:

toXML in class org.griphyn.vdl.Chimera

Parameters:

stream - is a stream opened and ready for writing. This can also be a string stream for efficient output.

indent - is a String of spaces used for pretty printing. The initial amount of spaces should be an empty string. The parameter is used internally for the recursive traversal. If a null value is specified, no indentation nor linefeeds will be generated.

namespace - is the XML schema namespace prefix. If neither empty nor null, each element will be prefixed with this prefix, and the root element will map the XML namespace.

Throws:

IOException - if something fishy happens to the stream.
