ModuleTargetAttribute
is a preview API of the Java platform.
Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.
Models the
ModuleTarget
attribute, which can
appear on classes that represent module descriptors. This is a JDK-specific
attribute, which captures constraints on the target platform.
Delivered as a ClassElement
PREVIEW when
traversing the elements of a ClassModel
PREVIEW.
The specification of the ModuleTarget
attribute is:
TargetPlatform_attribute {
// index to CONSTANT_utf8_info structure in constant pool representing
// the string "ModuleTarget"
u2 attribute_name_index;
u4 attribute_length;
// index to CONSTANT_utf8_info structure with the target platform
u2 target_platform_index;
}
The attribute does not permit multiple instances in a given location. Subsequent occurrence of the attribute takes precedence during the attributed element build or transformation.
