de.calamanari.adl.sql.cnv.ColumnCondition

Record Components:

type - tells how this condition should be translated

operator - the operator to compare the column against the value

column - to be compared

parameters - one or multiple prepared parameters, see ColumnConditionType

public record ColumnCondition(ColumnConditionType type, de.calamanari.adl.irl.MatchOperator operator, AdlSqlColumn column, List<QueryParameter> parameters)
extends Record

A ColumnCondition carries the meta data and the prepared parameters related to a single column, which can either be a DataColumn (means a column related to an argName) or a FilterColumn to be tested against a value.

Column conditions apply to value matches and also to reference matches if the related column or referenced column has filters.
Additional column conditions can occur in the main WHERE-clause if the table the query is starting with has table filter columns.

ColumnCondition

public ColumnCondition(ColumnConditionType type,
 de.calamanari.adl.irl.MatchOperator operator,
 AdlSqlColumn column,
 List<QueryParameter> parameters)

Creates an instance of a ColumnCondition record class.

Parameters:

type - the value for the type record component

operator - the value for the operator record component

column - the value for the column record component

parameters - the value for the parameters record component

Method Details

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

the value of the column record component

parameters
