public class XVARNode

extends DataPrimitive

Author:

(C) P. Murray-Rust, 1996

XVARNode(String, SGMLTree)

childrenToString()

this is required as we have to deal with _PEL subnodes

createAndAdd(SGMLTree, int, Date)

create from a data entry as date and add to tree

createAndAdd(SGMLTree, int, double)

create from a data entry as float and add to tree

createAndAdd(SGMLTree, int, int)

create from a data entry as integer and add to tree

createAndAdd(SGMLTree, int, int, int, int, int, int, int)

create from a data entry as date and add to tree ; if hrs, sec are negative, they are ignored

createAndAdd(SGMLTree, int, String)

create from a data entry as string and add to tree

createAndAdd(SGMLTree, String, int, String)

create from a data entry as TYPE=type and add to tree

display()

Kicks off a ScrollableTopLevel which contains the object.

display(Graphics)

only for large chunks of text at present

displayAddress()

for an XVAR of ADDRESS, display it if possible

drawIcon(Graphics, int, int)

at some stage make this useful to subclasses

getDateValue()

note - if not a date, returns null

getFirstXVARChildhasAttval(SGMLNode, String, String)

get the first XVAR child of a node with given Attribute value OR NULL

getFirstXVARDescendantHasAttname(SGMLNode, String)

get the first XVAR descendant of a node with given Attribute name

getFirstXVARDescendantHasAttval(SGMLNode, String, String)

get the first XVAR descendant of a node with given Att value OR NULL

getFloatValue()

note - if not a float , returns 0

getIntegerValue()

note - if not an integer, returns 0

getStringValue()

note - if not a String , returns ""

mayContain(SGMLNode)

XVAR and ARRAY may node contain other nodes (except PEL).

process()

complex objects may require processing; override this.

setDisplayURLTOC(boolean)

do we display the URL target as a TOC or as the 'most important subobject'

setFloatValue(double)

setIntValue(int)

setStringValue(String)

showHelp()

display Help
