Bug 248031

Description Danny Ju 2008-09-19 16:52:06 EDT

Build ID: I20080617-2000

Steps To Reproduce:
org.eclipse.jpt.db.Column and its implementation class DTPColumnWrapper wrap DTP org.eclipse.datatools.modelbase.sql.tables.Column. But did not expose all the methods exposed by DTP Column.

We’d like to request enhancement to the interface/class to provide following methods:  
	/**
	 * Return whether the column is part of it's table's unique constraint.
	 */	
	public boolean isPartOfUniqueConstraint();
	
	/**
	 * Return whether the column is nullable.
	 */	
	public boolean isNullable();
	
	/**
	 * Return whether the column is of numeric type.
	 */	
	public boolean isNumeric() ;	

	/**
	 * Return precision of the column if it is NumericalDataType
	 * otherwise, return -1
	 */	
	public int getPrecision();	

	/**
	 * Return scale of the column if it is ExactNumericDataType
	 * otherwise, return -1
	 */	
	public int getScale();	

	/**
	 * Return size of the column:
	 * - if the column is CharacterStringDataType, return the length
	 * - otherwise, return -1
	 */	
	public int getLength() ;

These methods are necessary to generate appropriate JPA Entity annotations, e.g. 
	@Column(name="", nullable=false, precision=4)
