Class Exists

java.lang.Object

psdi.common.parse.TreeNodeAdapter

psdi.common.parse.BooleanTreeNodeAdapter

psdi.common.parse.Exists

All Implemented Interfaces:

TreeNode

public class Exists
extends BooleanTreeNodeAdapter

This Boolean function returns true when a related Mbo found that satisfies the expression. For example, the expression: exists (select 1 from poline where ponum = :ponum and siteid = :siteid and fincntrlid is not null) could be written as: custom('psdi.common.parse.Exists','POLINE', 'fincntrl is not null') Later, when this function is rolled into the expression parser. Exists(POLINE, fincntrl is not null)

Method Detail

childrenInfoString

protected java.lang.String childrenInfoString()

Description copied from class: TreeNodeAdapter

Sub-classes should override this method to return the result of toString on each child, separated by new lines. If the node has no children, this method should return null or the empty string. If the node has 3 children the output should look like:

\n
\n

Note there is no new line character after the last child.

Specified by:

childrenInfoString in class TreeNodeAdapter

parentInfoString

protected java.lang.String parentInfoString()

Description copied from class: TreeNodeAdapter

Sub-classes should override this method to create a string which provides information for the parent node only. The string created should be a single line.

Specified by:

parentInfoString in class TreeNodeAdapter
