Class EOSQLQualifier

java.lang.Object
  com.webobjects.eocontrol.EOQualifier
      com.webobjects.eoaccess.EOSQLQualifier

All Implemented Interfaces:

EOQualifierEvaluation, EOQualifierSQLGeneration, EOSQLExpression.SQLValue, Serializable

Deprecated. The class EOSQLQualifier is deprecated. Use EOAdaptorChannel.evaluateExpression() or EOFetchSpecification.setHints() instead.

public class EOSQLQualifier

extends EOQualifier

implements EOQualifierSQLGeneration, EOSQLExpression.SQLValue

EOSQLQualifier contains unstructured text that can be transformed into a SQL expression. EOSQLQualifier is provided for backwards compatibility with EOF 1.x products and to provide a way that programmers can create SQL expressions with any arbitrary SQL. In general, programmers should use EOQualifier whenever possible and use EOSQLQualifier only in cases that absolutely require it.

An EOSQLQualifier holds qualifications expressed in the target query language and rooted in a single EOEntity. EOSQLQualifier formats differ from EOQualifier formats. EOSQLQualifier formats are not parsed, they are simply scanned for keys and format characters. EOSQLQualifiers should only be used when one wants to use a query available in the database query language that cannot be expressed using the EOQualifier formats.

EOSQLQualifiers cannot be applied to objects in memory. See EOQualifierConcepts for more information.

Constructor Detail

EOSQLQualifier

public EOSQLQualifier(EOEntity entity,
                      String qualifierFormat,
                      Object[] arguments)

Deprecated.

Creates an EOSQLQualifier

Parameters:

entity - an EOEntity

qualifierFormat - a format String

arguments - an array of Objects to substitute into qualifierFormat

Method Detail

addQualifierKeysToSet

public void addQualifierKeysToSet(NSMutableSet qualKeys)

Deprecated.

Description copied from class: EOQualifier

Adds the receiver's qualifier keys to qualifierKeys. The subclasses in the EOControl framework do this by traversing the tree of qualifiers. Node qualifiers (such as EOAndQualifier) recursively invoke this method until they reach a leaf qualifier (such as EOKeyValueQualifier) which adds its key to the set.

Subclasses of EOQualifier must implement this method.

Specified by:

addQualifierKeysToSet in class EOQualifier

Parameters:

qualKeys - The mutable array of qualifier keys

clone

public Object clone()

Deprecated.

Description copied from class: EOQualifier

Returns an exact replica of the receiver.

Overrides:

clone in class EOQualifier

Returns:

The exact replica of the receiver.

conjoinWithQualifier

public void conjoinWithQualifier(EOSQLQualifier qualifier)

Deprecated.

disjoinWithQualifier

public void disjoinWithQualifier(EOSQLQualifier qualifier)

Deprecated.

encodeIntoPropertyList

public void encodeIntoPropertyList(NSMutableDictionary result)

Deprecated.

isEmpty

public boolean isEmpty()

Deprecated.

Returns true if the qualifier is empty, false otherwise.

Returns:

boolean true if the qualifier is empty

negate

public void negate()

Deprecated.

qualifierMigratedFromEntityRelationshipPath

public EOQualifier qualifierMigratedFromEntityRelationshipPath(EOEntity entity,
                                                               String relationshipPath)

Deprecated.

Description copied from interface: EOQualifierSQLGeneration

Creates a new EOQualifier by moving the qualifier from the source entity to the destination of the relationship path. All of the keys are migrated across the specified relationshipPath.

Specified by:

qualifierMigratedFromEntityRelationshipPath in interface EOQualifierSQLGeneration

Parameters:

entity - the source entity

relationshipPath - the migration relationship path

Returns:

the migrated EOQualifier

qualifierWithBindings

public EOQualifier qualifierWithBindings(NSDictionary bindings,
                                         boolean requiresAll)

Deprecated.

Description copied from class: EOQualifier

Returns a new qualifier substituting all variables with values found in bindings. If requiresAll is true, any variable not found in bindings throws an exception. If requiresAll is false, missing variable values cause the qualifier node to be pruned from the tree.

Specified by:

qualifierWithBindings in class EOQualifier

Parameters:

bindings - bindings dictionary

requiresAll - Value indicating if all the criteria are required

Returns:

new qualifier substituting all variables with values in bindings

schemaBasedQualifierWithRootEntity

public EOQualifier schemaBasedQualifierWithRootEntity(EOEntity entity)

Deprecated.

Description copied from interface: EOQualifierSQLGeneration

Returns an equivalent EOQualifier with object references replaced by foreign key references.

Specified by:

schemaBasedQualifierWithRootEntity in interface EOQualifierSQLGeneration

Parameters:

entity - the source entity

Returns:

the equivalent EOQualifier

setUsesDistinct

public void setUsesDistinct(boolean bool)

Deprecated.

sqlStringForSQLExpression

public String sqlStringForSQLExpression(EOSQLExpression sqlExpression)

Deprecated.

Description copied from interface: EOQualifierSQLGeneration

Returns the SQL text that is represented by the EOSQLExpression object.

Specified by:

sqlStringForSQLExpression in interface EOQualifierSQLGeneration

Parameters:

sqlExpression - the EOSQLExpression object to be converted into text

Returns:

the String equivalent

toString

public String toString()

Deprecated.

usesDistinct

public boolean usesDistinct()

Deprecated.

validateKeysWithRootClassDescription

public void validateKeysWithRootClassDescription(EOClassDescription classDesc)

Deprecated.

Description copied from class: EOQualifier

Ensures that the receiver contains keys and key paths that belong to or originate from classDescription. This method raises an exception if an unknown key is found, otherwise it returns null to indicate that the keys contained by the qualifier are valid.

Specified by:

validateKeysWithRootClassDescription in class EOQualifier

Parameters:

classDesc - The EOClassDescription to be checked with the receiver

valueForSQLExpression

public String valueForSQLExpression(EOSQLExpression context)

Deprecated.

Conformance to EOSQLExpression.SQLValue.

Specified by:

valueForSQLExpression in interface EOSQLExpression.SQLValue

Parameters:

context - specify SQL expression

Returns:

a String to be used to represent the receiver in an SQL statement
