Examples with ColumnFamily com.google.cloud.bigtable.admin.v2.models.ColumnFamily used on opensource projects

Example 1 with ColumnFamily

use of com.google.cloud.bigtable.admin.v2.models.ColumnFamily in project java-bigtable-hbase by googleapis.

the class ColumnDescriptorAdapter method adapt.

/**
 * Adapt a single instance of an HBase {@link org.apache.hadoop.hbase.HColumnDescriptor} to an
 * instance of {@link com.google.bigtable.admin.v2.ColumnFamily.Builder}.
 *
 * <p>NOTE: This method does not set the name of the ColumnFamily.Builder. The assumption is that
 * the CreateTableRequest or CreateColumnFamilyRequest takes care of the naming. As of now
 * (3/11/2015), the server insists on having a blank name.
 *
 * @param columnDescriptor a {@link org.apache.hadoop.hbase.HColumnDescriptor} object.
 * @return a {@link com.google.bigtable.admin.v2.ColumnFamily.Builder} object.
