Class BaseNonStreamValue

java.lang.Object
  org.exoplatform.services.jcr.rmi.api.value.BaseNonStreamValue

All Implemented Interfaces:

java.io.Serializable, javax.jcr.Value, ExtendedValue, StatefulValue

Direct Known Subclasses:

BinaryValue, BooleanValue, DateValue, DoubleValue, LongValue, NameValue, PathValue, PermissionValue, ReferenceValue, StringValue

public abstract class BaseNonStreamValue
extends java.lang.Object
implements StatefulValue

The BaseNonStreamValue class implements the basic committed value state for non-stream values as a part of the State design pattern (Gof) used by this package.

This class implements all methods of the rmi.api.value.StatefullValue except getString and getType interface by always throwing an appropriate exception. Extensions of this class should overwrite methods as appropriate except for the getStream() which must throw an IllegalStateException for this line of committed non-stream states.

Specified by:

setOrderNumber in interface ExtendedValue

getStream

public java.io.InputStream getStream()
                              throws java.lang.IllegalStateException

Always throws IllegalStateException because only non-stream getters are available from this implementation.

This method is declared final to mark that this line of implementations does not provide access to InputStreams.

Specified by:

getStream in interface javax.jcr.Value

Returns:

nothing

Throws:

java.lang.IllegalStateException - as defined above.

getBoolean

public boolean getBoolean()
                   throws javax.jcr.ValueFormatException

Always throws a ValueFormatException. Implementations should overwrite if conversion to boolean is supported.

Specified by:

getBoolean in interface javax.jcr.Value

Returns:

nothing

Throws:

javax.jcr.ValueFormatException - If the value cannot be converted to a boolean.

getDate

public java.util.Calendar getDate()
                           throws javax.jcr.ValueFormatException

Always throws a ValueFormatException. Implementations should overwrite if conversion to Calender is supported.

Specified by:

getDate in interface javax.jcr.Value

Returns:

nothing

Throws:

javax.jcr.ValueFormatException - If the value cannot be converted to a Calendar instance.

getDouble

public double getDouble()
                 throws javax.jcr.ValueFormatException

Always throws a ValueFormatException. Implementations should overwrite if conversion to double is supported.

Specified by:

getDouble in interface javax.jcr.Value

nothing

Throws:

javax.jcr.ValueFormatException - If the value cannot be converted to a double.

getLong

public long getLong()
             throws javax.jcr.ValueFormatException

Always throws a ValueFormatException. Implementations should overwrite if conversion to long is supported.

Specified by:

getLong in interface javax.jcr.Value

Returns:

nothing

Throws:

javax.jcr.ValueFormatException - If the value cannot be converted to a long.

getValueFormatException

protected javax.jcr.ValueFormatException getValueFormatException(java.lang.String destType)

Returns a ValueFormatException with a message indicating what kind of type conversion is not supported.

Parameters:

destType - The name of the value type to which this value cannot be converted.

Returns:

nothing
