Specified by:

intern

public Table intern()
Description copied from interface: Table
Returns a canonical representation for the table object.

This method behaves much like String.intern(). A pool of tables, initially empty, is maintained privately.

When the intern method is invoked, if the pool already contains a table equal to this Table object as determined by the equals(Object) method, then the table from the pool is returned. Otherwise, this Table object is added to the pool and a reference to this Table object is returned.

It follows that for any two tables t1 and t2, t1.intern() == t2.intern() is true if and only if t1.equals(t2) is true.

Specified by:
intern in interface Table
Returns:
a table that is equivalent to this table, but is guaranteed to be from a pool of unique tables.

exists

public boolean exists(StoreManager.MgmtTransaction mtx)
               throws java.sql.SQLException
Description copied from interface: Table
Tests if the database table exists.

Specified by:
exists in interface Table
Parameters:
mtx - the active management transaction
Returns:
true if the table exists in the database, false otherwise.
Throws:
java.sql.SQLException

hashCode

public int hashCode()

equals

public boolean equals(java.lang.Object obj)

toString

public final java.lang.String toString()
