oracle.jbo.domain
Class Raw

java.lang.Object
oracle.sql.RAW
oracle.jbo.domain.Raw

All Implemented Interfaces:

java.io.Serializable

public class Raw

extends RAW

implements java.io.Serializable

This class provides a lightweight wrapper for oracle.sql.Raw, the Java representation of the RAW database type. This wrapper allows an instance of the oracle.sql.Raw to be used as an immutable Domain object.

The intent of many of the methods in this class is to wrap the corresponding method in the oracle.sql class such that it returns an instance of an oracle.jbo.domain.* object.

Raw objects consist of data (a byte array) and a Domain type code.

The oracle.jbo.domain.Raw class is the Java representation of the underlying database type that you must use if you want to exploit the domain feature of Business Components for Java.

Since:

JDeveloper 3.0

Constructor Detail

Raw

public Raw()

Creates a default Raw Domain object.

This constructor does not create a null object. To create a null object, use the oracle.jbo.domain.NullValue object to indicate null.

Raw

public Raw(Raw value)
    throws java.sql.SQLException

Creates a Raw object identical to an existing Raw object.

Parameters:

value - a Raw Domain object.

Throws:

java.sql.SQLException - never.

Raw

public Raw(byte[] value)

Internal: Applications should not invoke this constructor.

Creates a Raw Domain object from the given byte array.

Parameters:

value - a value returned by a previous call to getBytes() on an SQL object compatable with Raw.

Raw

public Raw(java.lang.String value)
    throws java.sql.SQLException

Creates a Raw Domain object from a Java String.

Parameters:

value - a textual representation of a Raw object.

Throws:

SQLException - if the representation is invalid.

java.sql.SQLException

Raw

public Raw(java.lang.Object value)
    throws java.sql.SQLException

Creates a Raw Domain object from a Java Object.

The Object must be an instance of byte[], which becomes the body of the Raw object, or an instance of String, which is first converted into a byte array.

Parameters:

value - an arbitrary Object.

Throws:

java.sql.SQLException - if the object is not an instance of byte[] or String.

Method Detail

getCustomDatumFactory

public static CustomDatumFactory getCustomDatumFactory()

Internal: Applications should not invoke this method.

Initializes the Raw Domain. This method is invoked when Business Components for Java is initialized.

Returns:

the CustomDatumFactory for the Raw Domain.

toDatum

public Datum toDatum(oracle.jdbc.driver.OracleConnection conn)
              throws java.sql.SQLException

Internal: Applications should not invoke this method.

Converts this Raw Domain object back into an SQL RAW object.

Returns:

A Datum containing RAW object.

Throws:

SQLException - Never.

java.sql.SQLException

getValue

public byte[] getValue()

Return a byte[] object with this domain's value. This method may be used to access the value for this domain in EL-expressions.

getData

public java.lang.Object getData()

Internal: Applications should not invoke this method. Converts this to a JDBC object.

Returns:

the internal byte array of this as a JBDC object.

setContext

public void setContext(DomainOwnerInterface owner,
                       Transaction trans,
                       java.lang.Object ctx)

Internal: Applications should not invoke this method.

toString

public java.lang.String toString()

For testing purposes only: converts this to a character string.

equals

public boolean equals(java.lang.Object other)

Tests this for equality with another object.

The argument is converted to a Raw object, if necessary.

Parameters:

other - an arbitrary Object.

Returns:

true if conversion was successful and the converted argument is identical to this.

hashCode

public int hashCode()

Computes a hash code for this.

Returns:

the hash code of this.

getXMLDomainFactory

public static XMLDomainFactory getXMLDomainFactory(java.lang.Class attrClass)

Internal: Applications should not use this method.
