ArgString
public ArgString()
Default c'tor: Construct a hollow shell and allow further information to be added later.
-
ArgString
public ArgString(java.lang.String executable)
Constructs an applications without arguments.- Parameters:
executable
- is the name of the application.
-
ArgString
public ArgString(java.lang.String executable, java.lang.String value)
Constructs an applications with arguments.- Parameters:
executable
- is the name of the application.value
- represents the argument line passed.

Method Detail
-
appendValue
public void appendValue(java.lang.String fragment)
Appends a piece of text to the existing text.- Specified by:
appendValue
in interfaceHasText
- Parameters:
fragment
- is a piece of text to append to existing text. Appendingnull
is a noop.
-
getValue
public java.lang.String getValue()
Accessor- Specified by:
getValue
in interfaceHasText
- Specified by:
getValue
in classArguments
- Returns:
- string representing arguments, or
null
if there is no such string. The empty string is also possible. - See Also:
setValue(String)
-
setValue
public void setValue(java.lang.String value)
Accessor.- Specified by:
setValue
in interfaceHasText
- Parameters:
value
- is the new value to set.- See Also:
getValue()
-
toXML
public java.lang.String toXML(java.lang.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 aString
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(java.io.Writer stream, java.lang.String indent, java.lang.String namespace) throws java.io.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 classorg.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 aString
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 anull
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:
java.io.IOException
- if something fishy happens to the stream.- See Also:
