er.extensions.eof
Class ERXKey<T>

java.lang.Object
  er.extensions.eof.ERXKey<T>

Type Parameters:

T - the type of the value of this key

public class ERXKey<T>
extends java.lang.Object

ERXKey provides a rich wrapper around a keypath. When combined with chainable qualifiers, ERXKey provides a starting point for the qualifier chain. As an example:

 <code>
 public class Person extends ERXGenericRecord {
   ...
   public static final ERXKey<Country> country = new ERXKey<Country>(Person.COUNTRY_KEY);
   public static final ERXKey<NSTimestamp> birthDate = new ERXKey<NSTimestamp>(Person.BIRTH_DATE_KEY);
   ...
 }
 
   Country germany = ...;
   NSTimestamp someRandomDate = ...;
   EOQualifier qualifier = Person.country.is(germany).and(Person.birthDate.after(someRandomDate));
 </code>

append

public <U> ERXKey<U> append(java.lang.String key)

Returns a new ERXKey that appends the given key to this keypath. For instance, if this key is "person" and you add "firstName" to it, this will return a new ERXKey "person.firstName". Note: ERXKey has a limitation that it will not return the proper generic type if you attempt to build a keypath extension of an NSArray. For instance, ERXKey<NSArray<Person>>.append(ERXKey<String>) will return ERXKey<String> when, in fact, it should be ERXKey<NSArray<String>>. This is a limitation due to type erasure with generics that we cannot currently resolve this problem.

Type Parameters:

U - the type of the next key

Parameters:

key - the key to append to this keypath

Returns:

the new appended key

dot

public <U> ERXKey<U> dot(java.lang.String key)

Calls append(key)

Type Parameters:

U - the key type

key - the key to append to this keypath

Returns:

the new appended key

append

public <U> ERXKey<U> append(ERXKey<U> key)

Returns a new ERXKey that appends the given key to this keypath. For instance, if this key is "person" and you add "firstName" to it, this will return a new ERXKey "person.firstName". Note: ERXKey has a limitation that it will not return the proper generic type if you attempt to build a keypath extension of an NSArray. For instance, ERXKey<NSArray<Person>>.append(ERXKey<String>) will return ERXKey<String> when, in fact, it should be ERXKey<NSArray<String>>. This is a limitation due to type erasure with generics that we cannot currently resolve this problem.

Type Parameters:

U - the type of the next key

Parameters:

key - the key to append to this keypath

Returns:

the new appended key

dot

public <U> ERXKey<U> dot(ERXKey<U> key)

the new appended key

appendAsArray

public <U> ERXKey<com.webobjects.foundation.NSArray<U>> appendAsArray(ERXKey<U> key)

Returns a new ERXKey that appends the given key to this keypath. For instance, if this key is "person" and you add "firstName" to it, this will return a new ERXKey "person.firstName".

 <code>
                ERXKey<String> k = new ERXKey<String>("foo");
                ERXKey<NSArray<String>> a = new ERXKey<NSArray<String>>("foos");
                k = k.append(k);
                a = a.append(k);
                a = k.appendAsArray(k);
                k = k.appendAsArray(k);
                a = k.appendAsArray(a);
                a = a.appendAsArray(k);
                a = a.appendAsArray(a);
 </code>
 

Type Parameters:

U - the type of the next key in the array

Parameters:

key - the key to append to this keypath

Returns:

the new appended key

dotArray

public <U> ERXKey<com.webobjects.foundation.NSArray<U>> dotArray(ERXKey<U> key)

Calls appendAsArray(key).

Type Parameters:

U - the type

Parameters:

key - the key to append to this keypath

Returns:

the new append to this keypath

valueInObject

public T valueInObject(java.lang.Object obj)

Returns the value of this keypath on the given object. Note: If you ERXKey representation a keypath through an NSArray, this method will result in a ClassCastException. See the 'Note' on .append(..) for further explanation.

Parameters:

obj - the target object to apply this keypath on

Returns:

the value of the keypath on the target object

rawValueInObject

public java.lang.Object rawValueInObject(java.lang.Object obj)

Returns the value of this keypath on the given object.

Parameters:

obj - the target object to apply this keypath on

Returns:

the value of the keypath on the target object

Parameters:

value - the value to set

obj - the object to set the value on

prefix

public com.webobjects.eocontrol.EOQualifier prefix(com.webobjects.eocontrol.EOQualifier qualifier)

Prefixes the keys in the given qualifier with this key. For example, if you have a qualifier on Company of name = 'mDT' and you want to find Person eo's whose companies match that qualifier, you need to prefix all the keys in the qualifier to be "company.whatever" (to go through the company relationship on Person) -- so in the example you would need company.name = 'mDT'. Prefix provides a mechanism to do that. Person.COMPANY.prefix(ERXQ.is("name", "mDT")) is equivalent to ERXQ.is("company.name", "mDT")

Parameters:

qualifier - the qualifier to prefix

Returns:

a qualifier with all of its keys prefixed with this key

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
