              java.lang.String name,
              java.lang.String type,
              boolean nullable)

Construct a Column.

Parameters:

name -

nullable -

Method Detail

getType

public java.lang.String getType()

Returns:

the type

setType

public void setType(java.lang.String type)

Parameters:

type - the type to set

isNullable

public boolean isNullable()

Returns:

the nullable

setNullable

public void setNullable(boolean nullable)

Parameters:

nullable - the nullable to set

getOrder

public int getOrder()

Returns:

the order

setOrder

public void setOrder(int order)

Parameters:

order - the order to set

isAutoIncrement

public boolean isAutoIncrement()

Returns:

whether the column has an auto-increment flag set.

setAutoIncrement

public void setAutoIncrement(boolean autoIncrement)

Parameters:

autoIncrement - whether this column has the auto-increment flag set.

hashCode

public int hashCode()

Overrides:

hashCode in class AbstractDbObject

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class AbstractDbObject

doDiff

protected void doDiff(DbObject right,
                      DiffContext ctx,
                      Result.Strength strength)

Description copied from class: AbstractDbObject

Override this method to provide subclass specific diffing logic.

Overrides:

doDiff in class AbstractDbObject

accept

public void accept(DbObjectVisitor visitor)

Description copied from interface: DbObject

Allows a visitor to be invoked against this DbObject. Implementations should ensure that child objects are visited first (by calling accept on them) before invoking the visitor on itself.

sameAs

public boolean sameAs(DbObject other)

Description copied from interface: DbObject

Are the two DbObjects logically the same? For example two Index objects may have different names, but are the same index as they both index the same columns for the same table.

If two objects a and b have the same logical identity, it does not mean that a.equals(b) == true. The two objects may well have differences and will be flagged as such by the schema comparison tool. When a.sameAs(b) == true it makes it easier to show the differences as related, i.e. a and b are different rather than, a is only in the 'left' tree and b is only in the 'right' tree.

Specified by:

sameAs in interface DbObject

Overrides:

sameAs in class AbstractDbObject

Returns:
