Method Detail

### dependsOnContext

    public boolean dependsOnContext()

  Description copied from interface: `ContextDependent`
  Determines whether this object actually depends on context.

  Specified by:
    `dependsOnContext` in interface `ContextDependent`

                         int index,
                         GraphState gs)

  Specified by:
    `getKnot` in interface `KnotVector`

### getManageableType

### writeStamp

    public void writeStamp(Cache.Entry cache,
                           GraphState gs)

  Description copied from interface: `ContextDependent`
  Writes a stamp of the context into `cache`. Based on this stamp, a cache detects whether the context of this object has changed or not.

  Specified by:
    `writeStamp` in interface `ContextDependent`
  Overrides:
    `writeStamp` in class `ContextDependentBase`
  Parameters:
    `cache` - a cache entry to write the stamp
    `gs` - the current graph state
