Field Detail

caseSensitive

protected boolean caseSensitive

True if evaluations should be case sensitive

wildcards

protected boolean wildcards

True if wildcards are allowed

name

protected java.lang.String name

An ID that can be used to identify each single element uniquely.

typeCondition

protected java.lang.String typeCondition

This field is used in different ways depending on the derived object. For a pattern element, it defines the type of query to evaluate, for example, QueryConst.XML, TEXT, ASTEXT or NUMERICAL, but for a pattern constraint, it is used t define the constraint condition, for example TextConst.CONTAINS or AiHeuristicConst.GT, etc.

value

protected java.lang.String value

The element value, for example, to compare a condition with, from either side of the operand

valueType

protected java.lang.String valueType

The type of value to be evaluated. This is not usually required, but might be useful for the mathematical operations.
