Class Type

A Java field or method type. This class can be used to make it easier to manipulate type and method descriptors.

🏭 Constructors

constructor

new Type(sort: number, buf: null | string, off: number, len: number): Type

Constructs a reference type.

Parameters

• sort: number the sort of the reference type to be constructed.
• buf: null | string a buffer containing the descriptor of the previous type.
• off: number the offset of this descriptor in the previous buffer.
• len: number the length of this descriptor.

Return Type

• Type
