Class TypedStringValue

java.lang.Object
  extended by org.springframework.beans.factory.config.TypedStringValue
All Implemented Interfaces:
BeanMetadataElement

public class TypedStringValue
extends java.lang.Object
implements BeanMetadataElement

Holder for a typed String value. Can be added to bean definitions in order to explicitly specify a target type for a String value, for example for collection elements.

This holder will just store the String value and the target type. The actual conversion will be performed by the bean factory.

1.2

Constructor Detail

TypedStringValue

public TypedStringValue(java.lang.String value)
Create a new TypedStringValue for the given String value.

Parameters:
value - the String value

public TypedStringValue(java.lang.String value,
                        java.lang.Class targetType)
Create a new TypedStringValue for the given String value and target type.

Parameters:
value - the String value
targetType - the type to convert to

public TypedStringValue(java.lang.String value,
                        java.lang.String targetTypeName)
Create a new TypedStringValue for the given String value and target type.

Parameters:
value - the String value
targetTypeName - the type to convert to
Method Detail

setValue

public void setValue(java.lang.String value)
Set the String value.

Only necessary for manipulating a registered value, for example in BeanFactoryPostProcessors.

See Also:
PropertyPlaceholderConfigurer

getValue

public java.lang.String getValue()
Return the String value.


setTargetType

public void setTargetType(java.lang.Class targetType)
Set the type to convert to.

Only necessary for manipulating a registered value, for example in BeanFactoryPostProcessors.

See Also:
PropertyPlaceholderConfigurer

getTargetType

public java.lang.Class getTargetType()
Return the type to convert to.


setTargetTypeName

public void setTargetTypeName(java.lang.String targetTypeName)
Specify the type to convert to.


getTargetTypeName

public java.lang.String getTargetTypeName()
Return the type to convert to.


hasTargetType

public boolean hasTargetType()
Return whether this typed String value carries a target type .


resolveTargetType

public java.lang.Class resolveTargetType(java.lang.ClassLoader classLoader)
                                  throws java.lang.ClassNotFoundException
Determine the type to convert to, resolving it from a specified class name if necessary. Will also reload a specified Class from its name when called with the target type already resolved.

Parameters:
classLoader - the ClassLoader to use for resolving a (potential) class name
Returns:
the resolved type to convert to
Throws:
java.lang.ClassNotFoundException - if the type cannot be resolved

setSource

public void setSource(java.lang.Object source)
Set the configuration source Object for this metadata element.

The exact type of the object will depend on the configuration mechanism used.

Description copied from interface: BeanMetadataElement
Return the configuration source Object for this metadata element (may be null).

Specified by:
getSource in interface BeanMetadataElement

setSpecifiedTypeName

public void setSpecifiedTypeName(java.lang.String specifiedTypeName)

getSpecifiedTypeName

public java.lang.String getSpecifiedTypeName()
Return the type name as actually specified for this particular value, if any.


setDynamic

public void setDynamic()
Mark this value as dynamic, i.e. as containing an expression and hence not being subject to caching.


isDynamic

public boolean isDynamic()
Return whether this value has been marked as dynamic.
