Constructor Detail

ForeignKey

public ForeignKey(String name)

ForeignKey

public ForeignKey(Table table,
                  String fkName,
                  String localColumn,
                  String targetTable,
                  String targetColumn)

Constructor.

Parameters:

table - the parent table

fkName - String

localColumn - String

targetTable - String

targetColumn - String

Method Detail

getLocalColumn

public String getLocalColumn()

Returns:

the localColumn

setLocalColumn

public void setLocalColumn(String localColumn)

Parameters:

localColumn - the localColumn to set

getTargetTable

public String getTargetTable()

Returns:

the targetTable

setTargetTable

public void setTargetTable(String targetTable)

Parameters:

targetTable - the targetTable to set

getTargetColumn

public String getTargetColumn()

Returns:

the targetColumn

setTargetColumn

public void setTargetColumn(String targetColumn)

Parameters:

targetColumn - the targetColumn to set

hashCode

public int hashCode()

Overrides:

hashCode in class AbstractDbObject

equals

public boolean equals(Object obj)

Overrides:

equals in class AbstractDbObject

doDiff

protected void doDiff(DbObject right,
                      DiffContext ctx)

Description copied from class: AbstractDbObject

Override this method to provide subclass specific diffing logic.

Overrides:

doDiff in class AbstractDbObject

Parameters:

right - DbObject

ctx - DiffContext

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.

Parameters:

visitor - DbObjectVisitor

getTypeName

public String getTypeName()

Description copied from interface: DbObject

Type name, e.g. "column", "foreign key"

Specified by:

getTypeName in interface DbObject

Overrides:

getTypeName in class AbstractDbObject

Returns:

String

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

Parameters:

other - DbObject

Returns:

boolean
