Method Detail

ofValue

public static Target ofValue(java.lang.Object value,
                             ScopeData scopeData)

Creates a common target over a value, with known scope data.

ofMethodParam

public static Target ofMethodParam(MethodParam methodParam,
                                   java.lang.Object object)

Creates a common target over a method param.

ofMethodParam

public static Target ofMethodParam(MethodParam methodParam,
                                   java.util.function.Function<java.lang.Class,java.lang.Object> valueInstanceCreator)

type

public java.lang.Class type()

Returns targets type, if specified.

resolveType()

resolveType

public java.lang.Class resolveType()

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

value

public java.lang.Object value()

Returns target value, if specified.

scopeData

public ScopeData scopeData()

Returns associated scope data.

readValue

public java.lang.Object readValue(InjectionPoint injectionPoint)

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 a successful operation.

readValue

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

writeValue

public void writeValue(InjectionPoint injectionPoint,
                       java.lang.Object propertyValue,
                       boolean silent)

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

writeValue

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