Method Detail

getVariables

public java.lang.String[] getVariables()
                                throws BuildException

get the properties as an array; this is an override of the superclass, as it evaluates all the properties

Overrides:

getVariables in class Environment

the array of definitions; may be null

Throws:

BuildException

addDefinitionsToList

public void addDefinitionsToList(java.util.ListIterator listIt)

add all definitions (including property sets) to a list

Parameters:

listIt - list iterator supporting add method

size

public int size()

This method gets the size of the sysproperties instance. This merges all property sets, so is not an O(1) operation.

Returns:

the size of the sysproperties instance

setSystem

public void setSystem()
               throws BuildException

cache the system properties and set the system properties to the new values

Throws:

BuildException - if Security prevented this operation

restoreSystem

public void restoreSystem()
                   throws BuildException

restore the system properties to the cached value

Throws:

BuildException - if Security prevented this operation, or there was no system properties to restore

clone

public java.lang.Object clone()

deep clone

Overrides:

clone in class java.lang.Object

Returns:

a cloned instance of SysProperties

addSyspropertyset

public void addSyspropertyset(PropertySet ps)

add a propertyset to the total set

Parameters:

ps - the new property set
