Class TypedStringValue

java.lang.Object
  org.springframework.beans.factory.config.TypedStringValue

All Implemented Interfaces:

BeanMetadataElement

public class TypedStringValue
extends 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.

Since:

1.2

Constructor Detail

TypedStringValue

public TypedStringValue(String value)

Create a new TypedStringValue for the given String value.

Parameters:

value - the String value

TypedStringValue

public TypedStringValue(String value,
                        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

TypedStringValue

public TypedStringValue(String value,
                        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(String value)

Set the String value.

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

See Also:

PropertyPlaceholderConfigurer

getValue

public String getValue()

Return the String value.

setTargetType

public void setTargetType(Class targetType)

Set the type to convert to.

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

See Also:

PropertyPlaceholderConfigurer

getTargetType

public Class getTargetType()

Return the type to convert to.

setTargetTypeName

public void setTargetTypeName(String targetTypeName)

Specify the type to convert to.

getTargetTypeName

public String getTargetTypeName()

Return the type to convert to.

hasTargetType

public boolean hasTargetType()

Return whether this typed String value carries a target type .

resolveTargetType

public Class resolveTargetType(ClassLoader classLoader)
                        throws 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:

ClassNotFoundException - if the type cannot be resolved

setSource

public void setSource(Object source)

Set the configuration source Object for this metadata element.

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

getSource

public Object getSource()

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(String specifiedTypeName)

Set the type name as actually specified for this particular value, if any.

getSpecifiedTypeName

public 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.

equals

public boolean equals(Object other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
