Constructor Detail

JDFSpawn

public JDFSpawn(JDFNode nodeToSpawn)

Parameters:

nodeToSpawn - the node to be spawned

Method Detail

setNode

public void setNode(JDFNode newNode)

set the node to spawn

Parameters:

newNode - the node to set

Throws:

JDFException - if node is NOT in the same document as the initial node

spawn

public JDFNode spawn()

spawn a node; url is the file name of the new node, vRWResourceUsage is the vector of Resources Usages (or Names if no usage exists for the process) that are spawned RW, all others are spawned read only; vParts is the vector of part maps that are to be spawned, defaults to no part, i.e. the whole thing the format is one of:
ResName:Input
ResName:Output
ResName:ProcessUsage

Returns:

The spawned node

Since:

050831 added bCopyComments @ tbd enhance nested spawning of partitioned nodes default: spawn(parentURL, null, null, null, false, false, false, false)

cleanSpawnedResources

public Collection<JDFResource> cleanSpawnedResources()

cleans up node so that no multiple spawnIDs remain
removes SpawnIDS and SpawnStatus from all resources that are spawnedRW by this spawn;
note that the vRWResources_in and vSpawnParts MUST be populated
audits are not modified

Returns:

the list of cleaned resource leaves, null if no cleanup was necessary

checkSpawnedResources

public Collection<JDFResource> checkSpawnedResources()

return the resources that would be spawned RW multiple times

Returns:

Collection: set of resources or resource partitions that would be spawned rw multiple times null if all is well

calcAuditSpawnIDs

protected void calcAuditSpawnIDs(JDFSpawned spawnAudit,
                     HashSet<String> vvRO,
                     HashSet<String> vvRW)

spawnInformative

public JDFNode spawnInformative()

spawn a node in informative mode without modifying the root JDF; url is the file name of the new node, the parameters except for the list of rw resources, which are by definition empty, are identical to those of Spawn vRWResourceUsage is the vector of Resources Usages, Resource Names or Resource IDs that are spawned RW, all others are spawned read only; vParts is the vector of part maps that are to be spawned, defaults to no part, i.e. the whole thing

Returns:

JDFDoc: The spawned node's owner document.
