Examples with ModelStatus org.eclipse.core.resources.mapping.ModelStatus used on opensource projects

Example 1 with ModelStatus

use of org.eclipse.core.resources.mapping.ModelStatus in project knime-core by knime.

the class MoveModelProvider method validateChange.

/**
 * Checks if a KNIIME workflow project is intended to be renamed. The reason
 * is, that at the moment the KNIME core saves an absolute path for storage
 * reasons. If renamed save actions would fail.
