                                                     ColumnTypeInformation columnType)

Description copied from interface: AggregateSupport

Returns the custom read expression to use for column. Replaces the given placeholder in the given template by the custom read expression to use for column.

Specified by:

aggregateComponentCustomReadExpression in interface AggregateSupport

Overrides:

aggregateComponentCustomReadExpression in class AggregateSupportImpl

Parameters:

template - The custom read expression template of the column

placeholder - The placeholder to replace with the actual read expression

aggregateParentReadExpression - The expression to the aggregate column, which contains the column

column - The column within the aggregate type, for which to return the read expression

aggregateColumnType - The type information for the aggregate column

columnType - The type information for the column within the aggregate type

aggregateComponentAssignmentExpression

public String aggregateComponentAssignmentExpression(String aggregateParentAssignmentExpression,
                                                     String column,
                                                     ColumnTypeInformation aggregateColumnType,
                                                     ColumnTypeInformation columnType)

Description copied from interface: AggregateSupport

Returns the assignment expression to use for column, which is part of the aggregate type of aggregatePath.

Specified by:

aggregateComponentAssignmentExpression in interface AggregateSupport

Overrides:

aggregateComponentAssignmentExpression in class AggregateSupportImpl

Parameters:

aggregateParentAssignmentExpression - The expression to the aggregate column, which contains the column

column - The column within the aggregate type, for which to return the assignment expression

aggregateColumnType - The type information for the aggregate column

columnType - The type information for the column within the aggregate type

requiresAggregateCustomWriteExpressionRenderer
