Constructs an applications without arguments.- Parameters:
executable
- is the name of the application.
-
CommandLine
public CommandLine(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.
-
getExecutable
public java.lang.String getExecutable()
Accessor- See Also:
setExecutable(String)
-
setExecutable
public void setExecutable(java.lang.String executable)
Accessor.- Parameters:
executable
-- See Also:
getExecutable()
-
getValue
public java.lang.String getValue()
Accessor- Specified by:
getValue
in interfaceHasText
- 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()
-
toString
public void toString(java.io.Writer stream) throws java.io.IOException
Converts the active state into something meant for human consumption. The method will be called when recursively traversing the instance tree.- Specified by:
toString
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.- Throws:
java.io.IOException
- if something fishy happens to the stream.
-
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:
