Examples with EventListener org.apache.ignite.internal.manager.EventListener used on opensource projects

Example 1 with EventListener

use of org.apache.ignite.internal.manager.EventListener in project ignite-3 by apache.

the class TableManager method tableSchema.

/**
 * Return table schema of certain version from history.
 *
 * @param tblId     Table id.
 * @param schemaVer Schema version.
 * @return Schema descriptor.

    ExtendedTableConfiguration tblCfg = ((ExtendedTableConfiguration) tablesCfg.tables().get(table.name()));
    if (schemaVer <= table.schemaView().lastSchemaVersion()) {
        return getSchemaDescriptorLocally(schemaVer, tblCfg);
    }
    CompletableFuture<SchemaDescriptor> fut = new CompletableFuture<>();
    var clo = new EventListener<TableEventParameters>() {

        @Override
