getExportIdentifier

public String getExportIdentifier()

从接口复制的说明: Exportable

Get a unique identifier to make sure we are not exporting the same database structure multiple times.

返回:

The exporting identifier.

disableCreation

public void disableCreation()

isCreationEnabled

public boolean isCreationEnabled()

setName

public void setName(String name)

覆盖:

setName 在类中 Constraint

sqlConstraintString

public String sqlConstraintString(Dialect dialect,
                                  String constraintName,
                                  String defaultCatalog,

getReferencedTable

public Table getReferencedTable()

setReferencedTable

public void setReferencedTable(Table referencedTable)
                        throws MappingException

抛出:

MappingException

alignColumns

public void alignColumns()

Validates that columnspan of the foreignkey and the primarykey is the same.

Furthermore it aligns the length of the underlying tables columns.

getReferencedEntityName

                            String defaultCatalog,
                            String defaultSchema)

指定者:

sqlDropString 在接口中 RelationalModel

覆盖:

sqlDropString 在类中 Constraint

isCascadeDeleteEnabled

public boolean isCascadeDeleteEnabled()

setCascadeDeleteEnabled

public void setCascadeDeleteEnabled(boolean cascadeDeleteEnabled)

isPhysicalConstraint

public boolean isPhysicalConstraint()

getReferencedColumns

public List getReferencedColumns()

Returns the referenced columns if the foreignkey does not refer to the primary key

isReferenceToPrimaryKey

public boolean isReferenceToPrimaryKey()

Does this foreignkey reference the primary key of the reference table

addReferencedColumns

public void addReferencedColumns(Iterator referencedColumnsIterator)

toString

public String toString()

覆盖:

toString 在类中 Constraint

generatedConstraintNamePrefix
