Example 11 with PColumnImpl

use of org.apache.phoenix.schema.PColumnImpl in project phoenix by apache.

the class ColumnExpressionTest method testSerializationWithNullMaxLength.

@Test

    int scale = 5;
    PName colName = PNameFactory.newName("c1");
    PColumn column = new PColumnImpl(colName, PNameFactory.newName("f1"), PVarchar.INSTANCE, null, scale, true, 20, SortOrder.getDefault(), 0, null, false, null, false, false, colName.getBytes());
    ColumnExpression colExp = new KeyValueColumnExpression(column);
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    DataOutputStream dOut = new DataOutputStream(baos);
