Method Details

getResultIterator

org.eclipse.birt.data.engine.api.IResultIterator getResultIterator()

getRowIndex

long getRowIndex()

skipTo

boolean skipTo(long rowIndex)
        throws org.eclipse.birt.core.exception.BirtException

org.eclipse.birt.core.exception.BirtException

next

boolean next()
      throws org.eclipse.birt.core.exception.BirtException

Throws:

org.eclipse.birt.core.exception.BirtException

getGroupId

String getGroupId(int groupLevel)

getStartingGroupLevel

int getStartingGroupLevel()
                   throws org.eclipse.birt.core.exception.BirtException

Returns the 1-based index of the outermost group in which the current row is the last row. For example, if a query contain N groups (group with index 1 being the outermost group, and group with index N being the innermost group), and this function returns a value M, it indicates that the current row is the last row in groups with indexes (M, M+1, ..., N ). -1 represents current row is a detail row. 0 represents the end of whole resultset

Returns:

1-based index of the outermost group in which the current row is the first row; (N+1) if the current row is not at the start of any group; 0 if the result set has no groups.

Throws:

org.eclipse.birt.core.exception.BirtException

getEndingGroupLevel

int getEndingGroupLevel()
                 throws org.eclipse.birt.core.exception.BirtException

Returns the 1-based index of the outermost group in which the current row is the first row. For example, if a query contain N groups (group with index 1 being the outermost group, and group with index N being the innermost group), and this function returns a value M, it indicates that the current row is the first row in groups with indexes (M, M+1, ..., N ).

Returns:

1-based index of the outermost group in which the current row is the first row; (N+1) if the current row is not at the start of any group; 0 if the result set has no groups.

Throws:

org.eclipse.birt.core.exception.BirtException

getResultMetaData
