Class Domain

io.tiledb.java.api.Domain

All Implemented Interfaces:

java.lang.AutoCloseable

public class Domain
extends java.lang.Object
implements java.lang.AutoCloseable

Represents the domain of an array.
A Domain defines the set of Dimension objects for a given array. The properties of a Domain derive from the underlying dimensions. A Domain is a component of an ArraySchema.
Note: The dimension can only be integral types, as well as floating point for sparse array domains.

Example:

 Context ctx = new Context();
 Domain domain = new Domain(ctx);

 // Note the dimension bounds are inclusive.
 Dimension<Integer> d1 = new Dimension<Integer>(ctx, "d1", Integer.class, new Pair<Integer, Integer>(-10, 10), 1);
 Dimension<Long> d2 = new Dimension<Long>(ctx, "d2", Long.class, new Pair<Long, Long>(1l, 10l), 1l);
 Dimension<Integer> d3 = new Dimension<Integer>(ctx, "d3", Integer.class, new Pair<Integer, Integer>(-100, 100), 10);

 domain.addDimension(d1);
 domain.addDimension(d2); // Throws error, all dims must be same type
 domain.addDimension(d3);

 domain.getType(); // TILEDB_INT32, determined from the dimensions
 domain.getRank(); // 2, d1 and d3

 ArraySchema schema = new ArraySchema(ctx, TILEDB_SPARSE);
 schema.setDomain(domain); // Set the array's domain
