Constructor Detail

HdmStoreCmd

public HdmStoreCmd(java.lang.String[] args)

Construct a HdmStoreCmd and process the command line arguments

Method Detail

processMultipleInstances

private java.util.ArrayList processMultipleInstances(java.lang.String command)

For this command, if its a compound command break it out into a number of simple commands e.g add [dean,mat] becomes: add [dean] add [mat]

expandEdgeNames

private java.lang.String expandEdgeNames(java.lang.String command)

If edge names have been given without types expand out e.g. add <

> ...... goes to add <>

processMacros

private java.lang.String processMacros(java.lang.String command)

Macros are short cuts. If you type a long edge name you vsn then identify and number it e.g. &1 for later reference. This rountine expands out any macros it finds.

replaceAny

private java.lang.String replaceAny(java.lang.String in,
                                    java.lang.String key,
                                    java.lang.String value)

If there is an occurance of string key in string in, then replace it with the string value and repeat until there are no more occurances. NVB the built in replace method on Strings only works on single characters.

processCommand

private void processCommand(java.lang.String command)

Takes a command in the full notation and processes it by making appropriate HDM Store API calls.

processAdd

private void processAdd(java.lang.String pType,
                        java.lang.String pValue)

Process an 'add' command - for either an edge or a node.

swapInternalCommas

private java.lang.String swapInternalCommas(java.lang.String in)

An edge may have an edge as one of its spans. Changing the commas on these 'internal edges' makes it possible to split the string into spans byt looking for commas.

chomp

private java.lang.String chomp(java.lang.String in)

Given a string, return the string less any preceeding or trailing spaces.

hideInternalSpaces

public static java.lang.String hideInternalSpaces(java.lang.String orig)

Change any spaces within an edge thats a span to another character

returnInternalSpaces

public static java.lang.String returnInternalSpaces(java.lang.String orig)

Changeback any seperators within an edge thats a span to spaces

changeInternalSpaces

private static java.lang.String changeInternalSpaces(java.lang.String orig,
                                                     java.lang.String from,
                                                     java.lang.String to)

Change internal seperators from one string to another

breakIntoCommands

private java.util.ArrayList breakIntoCommands(java.lang.String inputFileName)

Take the command file and break into an array list of individual commands
