Constructor Detail

Target

public Target(java.lang.Object value)

Creates target over the value. Injection will be done into the value, hence the name and the types are irrelevant. Used for action itself and action non-annotated arguments.

Target

public Target(java.lang.Object value,
              java.lang.Class type)

Target

public Target(java.lang.Class type)

Creates target over a type with given name. Injection is actually a type conversion from input content to the given type. Used for annotated arguments.

Method Detail

getType

public java.lang.Class getType()

Returns targets type, if specified.

resolveType()

resolveType

public java.lang.Class resolveType()

Resolves target type: either using provided type or type of the value.

getValue

public java.lang.Object getValue()

Returns target value, if specified.

setValue

public void setValue(java.lang.Object value)

Sets target value.

readValue

public java.lang.Object readValue(java.lang.String propertyName)

Reads value from the target. If something goes wrong, exception is thrown. We assume that outjection is controlled by developer and that each reading of a value must be successful operation.

readTargetProperty

public java.lang.Object readTargetProperty(ScopeData.Out out)

Reads target property.

writeValue

public void writeValue(java.lang.String propertyName,
                       java.lang.Object propertyValue,
                       boolean silent)

Writes value to this target. Depending on a flag, setting the value can be completely silent, when no exception is thrown and with top performances. Otherwise, an exception is thrown on a failure.

createValueInstance

protected void createValueInstance()

Creates new instance of a type and stores it in the value.
