Example 1 with IREngine

use of gate.creole.ir.IREngine in project gate-core by GateNLP.

the class SerialCorpusImpl method setIndexDefinition.

// readObject
@Override
public void setIndexDefinition(IndexDefinition definition) {
    if (definition != null) {
        this.getFeatures().put(GateConstants.CORPUS_INDEX_DEFINITION_FEATURE_KEY, definition);
