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.

  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`

### 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`
