Example 1 with NullUndefinedValidator

use of org.eclipse.n4js.validation.validators.flowgraphs.NullUndefinedValidator in project n4js by eclipse.

the class N4JSFlowgraphValidator method checkFlowGraphs.

/**
 * Triggers all flow graph related validations
 */
@Check

    // Note: The Flow Graph is NOT stored in the meta info cache. Hence, it is created here at use site.
    // In case the its creation is moved to the N4JSPostProcessor, care about an increase in memory consumption.
