Methods

The ProDataRelationMetaData class provides the following methods.

setColumns( )

Specifies the column properties that are to participate in primary-foreign key relationships between the parent and child tables of this ProDataRelationMetaData object, as specified by the overloaded methods:

Syntax

void setColumns(int parentColIdx, int childColIdx) void setColumns(int[] parentColIdxs, int[] childColIdxs)

parentColIdx

Specifies the 0-based index of a single column property in the parent ProDataObject type to use as the primary key.

childColIdx

Specifies the 0-based index of a single column property in the child ProDataObject type to use as the foreign key.

parentColIdxs

Specifies an array of 0-based indexes to column properties in the parent ProDataObject type to use as the primary key.

childColIdxs

Specifies an array of 0-based indexes to column properties in the child ProDataObject type to use as the foreign key.

When specifying parentColIdxs and childColIdxs, the arrays must be the same length. For either overloading, the corresponding parent and child column properties must be comparable.

getParentColumns( )

Syntax

int[] getChildColumns()

getParentTable( )

Returns the name of the parent table for this ProDataRelationMetaData object:

Syntax

getChildTable( )

Returns the name of the child table for this ProDataRelationMetaData object:

Syntax

getRelationName( )
