Class TypedStringValue
java.lang.Object
org.springframework.beans.factory.config.TypedStringValue
- All Implemented Interfaces:
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.

hasTargetType
public boolean hasTargetType()Return whether this typed String value carries a target type. -
resolveTargetType
@Nullable public Class<?> resolveTargetType(@Nullable 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

for this metadata element.The exact type of the object will depend on the configuration mechanism used.
-
getSource

for this metadata element (may benull
).- Specified by:
getSource
in interfaceBeanMetadataElement

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. -
