org.apache.fop.fo.flow.table.GridUnit
org.apache.fop.fo.flow.table.PrimaryGridUnit
public class PrimaryGridUnit extends GridUnit
This class represents a primary grid unit of a spanned cell. This is the "before-start" (top-left, usually) grid unit of the span.

      Get cell's layout manager.
      Returns:
      the cell's layout manager

    • getPrimary

      public PrimaryGridUnit getPrimary()
      Returns the before-start grid unit of the cell containing this grid unit.
      Overrides:
      getPrimary in class GridUnit

      the before-start grid unit of the cell containing this grid unit.

    • isPrimary

      public boolean isPrimary()
      Is this grid unit the before-start grid unit of the cell?
      Overrides:
      isPrimary in class GridUnit
      Returns:
      true if this grid unit is the before-start grid unit of the cell

    • setElements

      public void setElements(List elements)
      Sets the Knuth elements for the table cell containing this grid unit.
      Parameters:
      elements - a list of ListElement (?)

    • getElements

      public List getElements()
      Obtain the Knuth elements.
      Returns:
      a list of Knuth elements

    • getBeforeAfterBorderWidth

      public int getBeforeAfterBorderWidth()
      Returns the widths of the border-before and -after for this cell. In the separate border model the border-separation is included. In the collapsing model only half of them is counted, since the other halves belong to the neighbouring cells; also, the returned value is the maximum of the segments of each applicable grid unit.
      Returns:
      the sum of the before and after border widths

    • getBeforeBorderWidth

      public int getBeforeBorderWidth(int rowIndex, int which)
      Returns the width of the before-border for the given row-span of this cell. In the separate border model half of the border-separation is included. In the collapsing model only half of the border is counted, since the other half belongs to the preceding cell; also, the returned value is the maximum of the segments of each applicable grid unit.
      Parameters:
      rowIndex - index of the span for which the border must be computed, 0-based
      which - one of ConditionalBorder.NORMAL, ConditionalBorder.LEADING_TRAILING or ConditionalBorder.REST
      Returns:
      the before border width

    • getAfterBorderWidth

      public int getAfterBorderWidth(int rowIndex, int which)
      Returns the width of the before-after for the given row-span of this cell. In the separate border model half of the border-separation is included. In the collapsing model only half of the border is counted, since the other half belongs to the following cell; also, the returned value is the maximum of the segments of each applicable grid unit.
      Parameters:
      rowIndex - index of the span for which the border must be computed, 0-based
      which - one of ConditionalBorder.NORMAL, ConditionalBorder.LEADING_TRAILING or ConditionalBorder.REST
      Returns:
      the after border width

    • getAfterBorderWidth

      public int getAfterBorderWidth(int which)
      Returns the width of the before-after for the last row-span of this cell. See getAfterBorderWidth(int, int).
      Parameters:
      which - one of ConditionalBorder.NORMAL, ConditionalBorder.LEADING_TRAILING or ConditionalBorder.REST
      Returns:
      the after border width

    • getContentLength

      public int getContentLength()
      Returns:
      the length of the cell content

    • getRows

      public List<GridUnit[]> getRows()
      Returns the grid units belonging to the same span as this one.
      Returns:
      a list of GridUnit[], each array corresponds to a row

    • addRow

      public void addRow(GridUnit[] row)
      Add a row.
      Parameters:
      row - the row to be added

    • getRowIndex

      public int getRowIndex()
      Returns the index of the row this grid unit belongs to. This is the index, in the enclosing table part, of the first row spanned by the cell. Note that if the table has several table-body children, then the index grows continuously across them; they are considered to form one single part, the "body of the table".
      Returns:
      the index of the row this grid unit belongs to, 0-based.

    • getColIndex

      public int getColIndex()
      Returns the index of the column this grid unit belongs to.
      Returns:
      the column index, 0-based

    • getStartEndBorderWidths

      public int[] getStartEndBorderWidths()
      Returns the widths of the start- and end-borders of the span this grid unit belongs to.
      Returns:
      a two-element array containing the widths of the start-border then the end-border

    • toString

      public String toString()
      Overrides:
      toString in class GridUnit
