Parameters:

dataspyID -

getCustomFieldsAsDataspyFields

public List<DataspyField> getCustomFieldsAsDataspyFields()

Converts custom fields (DataspyCustomField) to normal dataspy fields (DataspyField)

attachCustomFields

public List<String> attachCustomFields(List<String> sqlStatements)

In the JPAGrids class we fetch all the fields that need to be selected, as a list. This method attaches the names of the of the custom fields to this list.

addCustomFieldsJoinClause

public String addCustomFieldsJoinClause(String sqlStatementFrom)

Adds the join clause to the SQL used to fetch the grid.

getCustomFieldsAsGridFields

public GridField[] getCustomFieldsAsGridFields(String dataspyID)

getCustomFieldsForGrid

public Map<String,DataField> getCustomFieldsForGrid(String gridID)

Fetches the custom fields possible for a grid. To do this it checks all custom fields belonging to dataspies belonging to a grid. Also fetches the type of the custom fields.

getCustomFieldJoinConditions

public String getCustomFieldJoinConditions()

For parts we have to use the deprecated join syntax with the plus (+) To make the join we add ANDs to the where clause.

getDataspyID

public String getDataspyID()
