This is a support class for implementing Joins in the Find query. This class holds information about a join so the Join portion of the Find can be written out correctly.
Inherits from: Libraries.Language.Object
Actions Summary Table
|Compare(Libraries.Language.Object object)||This action compares two object hash codes and returns an integer.|
|Equals(Libraries.Language.Object object)||This action determines if two objects are equal based on their hash code values.|
|GetHashCode()||This action gets the hash code for an object.|
|GetJoinCondition()||Returns this joins join condition|
|GetJoinType()||Returns the type of join this is.|
|GetTable()||Returns the table being joined to the query|
|SetJoinCondition(text condition)||Sets the join condition of this join.|
|SetTable(text table)||Sets the table to join to the query|
|SetToCrossJoin()||Sets the type of the join to a Cross Join|
|SetToInnerJoin()||Sets the type of the join to an Inner Join|
|SetToLeftJoin()||Sets the type of the join to a Left Join|
|SetToRightJoin()||Sets the type of the join to a Right Join|
This action compares two object hash codes and returns an integer. The result is larger if this hash code is larger than the object passed as a parameter, smaller, or equal. In this case, -1 means smaller, 0 means equal, and 1 means larger. This action was changed in Quorum 7 to return an integer, instead of a CompareResult object, because the previous implementation was causing efficiency issues.
Object o Object t integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smaller)
- Libraries.Language.Object: The object to compare to.
integer: The Compare result, Smaller, Equal, or Larger.
This action determines if two objects are equal based on their hash code values.
use Libraries.Language.Object use Libraries.Language.Types.Text Object o Text t boolean result = o:Equals(t)
- Libraries.Language.Object: The to be compared.
boolean: True if the hash codes are equal and false if they are not equal.
This action gets the hash code for an object.
Object o integer hash = o:GetHashCode()
integer: The integer hash code of the object.
Returns this joins join condition
Returns the type of join this is. The type is set using the SetToXJoin actions so the actual value for the join doesn't need to be remembered.
Returns the table being joined to the query
Sets the join condition of this join. In SQL this would be what goes in the ON clause. In the Find query this is converted using the filter converter.
Sets the table to join to the query
Sets the type of the join to a Cross Join
Sets the type of the join to an Inner Join
Sets the type of the join to a Left Join
Sets the type of the join to a Right Join
