Method Detail

renderTable

void renderTable(ElementTable table,
               int row,
               int col,
               Object value,
               Element cellContentElem,
               boolean isNew)

Renders as markup the specified value into the specified cell element.

The cell content element must be used to render below the value, usually as a text node.

Default implementation renders the specified value inside the first text node found below the specified cell content element.

Parameters:

table - the target table.

row - the row position.

col - the column position.

value - the value to render.

cellContentElem - the cell content element. This element is a hint, if provided, should be obtained by calling ElementTableStructure.getCellContentElement(ElementTable,int,int,Element).

isNew - true if this is the first time the markup is rendered. Default implementation ignores this parameter.

unrenderTable

void unrenderTable(ElementTable table,
                 int row,
                 int col,
                 Element cellContentElem)

Unrenders the markup of the specified table cell. This method is called before the markup is removed.

Default implementation does nothing.

Parameters:

table - the target table.

row - the row position.

col - the column position.

cellContentElem - the cell content element. This element is a hint, if provided, should be obtained by calling ElementTableStructure.getCellContentElement(ElementTable,int,int,Element).
